Dont you just hate building model boats?
Paint hardly dry on the last one, and here I go again! %% %%
Ulstein, the builders and Bourbon wouldnt let me have a linesplan, so I designed the hull myself.
Thank you to those who let me have some pics and information - you know who you are.
Anyway, here are the frames pasted onto plywood ready fro cutting out.
Ian

Here is a screen grab of what I hope it will turn out like.
Ian
-
i think i need some lessons in how to use delfship (is that what its called?) from yourself.
Its looking good. :-))
-
Got most of the frames cut and ready for mounting now, some pics:
Ian

Ian,
Looking good! O0
You would thing that the builders and the owners would be very happy that you thought that much of their vessel that you wanted to build a model of it. Now one reason that they did not want to give you a set of line drawings is that they may not exist as they are not needed to build it any more. They probably have a set of frame planes and some cross sections, the drawings that they need to build a ship are vastly different from the drawings that we need to build a model from. It used to be that the line plan was developed to prove the hull design, but that is now done with a cad package so the line drawing is not needed any more than a half model or a Admiralty model which were built to show what the ship was going to look like.

Looks great so far, very distinctive. What's her length/displacement?
-
length 1.2m and displacement will be approx 12kg.

Hi Ian & everyone.
I am new to this forum.I am also building a vsl with the X-Bow design, as my second scratch build attempt. I've taken the plans of Edda Fran and incorporated the X-Bow. I am not an experienced builder in any way, actualy the only other build that I've done so far is a simple 18"x7" River Towboat.
I've embark in this ambitious build cos I wanted something challenging to keep me occupied. So far it looks ok, I think. :}
So guys let me know what you think and any advice or comments.

Another excellent build,
How big is yours 3ns?
-
3ns,
That looks a good start to the build.
Forgive me if you already intend to do this, but I recommend cutting the centres out of the frames like I have - it gives you more space for access and fitting gizmo's. Same for the nose part of the keel - you will need the access I think.
Ian

Hi Martin.
Tks, she's 120cm x 25cm x 40cm.
I've used 5mm thickness Styrofoam covered with 1/16 balsa on both sides. I'll eventually seal these with finifshing resins.
I am leaning towards 2 units of Graupner Schottel Drive Unit I for propulsion and Graupner Bow Thruster. I'll try and have some scale fittings in her make look as scale as possible. Will have some working lights.
Hi Ian,
Tks for your advice. I will be doing the same, I've left it that way cos I am still working out things. I am thinking of getting some one to make a fiberglass hull out of this. But first need to check on how big a hole it'll put in my pocket. I tried cutting out the Portside & Starboardside frames, but as usual did some mistakes in the calculations. Now need to wait a bit longer to get that done cos my loving dog had a field day with my specs.
I just had an idea to have this baby pull my Gas Hydro. I am not too sure if that would be a good idea but thought it would be cool if she could do it. I think I will not be able to have a Tow Bar on the after without a Ballast system. But I am not familler with such systems or their setups. So I am still thinking about this.
Btw, I like the way you did the drawing and will be looking for ideas and inspiration through your build.
Once again. tks and have a nice weekend guys.

Now one reason that they did not want to give you a set of line drawings is that they may not exist as they are not needed to build it any more. They probably have a set of frame planes and some cross sections, the drawings that they need to build a ship are vastly different from the drawings that we need to build a model from.
That's one of the inept reasons I have heard <:(
For owners and shipyards modelbuilders are not a party.
They can't earn money with us, we only cost money. A more probable course is that there are a lot of new developments on the hulls.
Designing and developing new hull forms is a costly business, and giving away drawings to someone you don't know could be risky.
Who knows you are not somebody of a competitive shipyard?
So if they give away hullplans, it could became easier (cheaper) for other shipsyard to build the same ships without high development costs.
-
Just a little update:
After posting the last pics, something was niggling me that wasnt right - it turned out that I had cut the frames to one scale and the keel to a different scale DOH!!!
Anyway, I am now close to getting back to where I was , pics will come soon.
-
Hello
Humm nice works !
We can predict that soon there will be some Xbow on table of exhibition and sailing on ponds !
This one is my Xbow

(http://nsa07.casimages.com/img/2009/07/14/090714110837645776.jpg) (http://www.casimages.com)
She's 1.8m and around 60kg when full load.
A+ Xtian
-
Hi A+ Xtian ...looks good :-))....in both photographs I see a feint horizontal black line on the length of hull...is this the proposed waterline?
Did you have additional ballast in one picture?...... as the draft appears different...... O0...... Derek
-
Hi xtian29
Very nice :-)) :-)) What material did you use?
-
Hello
Yes the black line is the waterline and there is more ballast on the first picture.
The hull is in GRP and I've made a master with wood and foam.
Then there is three hull with different length for two friends and me - We don't want to reproduce a real ship and prefer free lance but looks like ones ! The largest (around 2 meter) will be a like Island Constructor with derrick and helo deck. The medium one (1.85 meter) will be an Anchor Handling Tug Supply close to the Bourbon Orca. the shorter one (1.78 m) is mine and also will be an AHTS but not like the Bourbon Orca (ROV capacity - regular props ....)

The X1 (larger hull) and the mould
(http://nsa08.casimages.com/img/2009/07/15/090715105335803731.jpg) (http://www.casimages.com)
The X1 (larger) and the X2 (medium) the middle part (without form like a cylinder is removed)
(http://nsa08.casimages.com/img/2009/07/15/090715110223624738.jpg) (http://www.casimages.com)
Inside the mould prior the X2 construction - in fact there is two serarate parts moulded and then both part are "welded" later.
As the keel and aft part are different from ship to ship, each modeler built his own

Hi everyone.
This is how far I've managed to reach, still a very looong way to go :(( .
Feel that the Bow frames are not in place, they don't seem to give the correct curve than I've seen on the build photos. will have work on them.

Hello
It looks good on the top hull zone but there is something wrong underwater no ?

Hi xtian.
Yes, there are some issues there that I need to workout. Still not too sure thou.
I just tried to see how it'll look. Any advice?
Tks
3ns
-
Hello
I think that you should install intermediate frames following the shape used by Boatmadman. And you have to also use longer pieces of wood to follow the curve.

Finally got my keel sorted out, and started with the planking;
-
Had a good day planking today. The hull shape is quite easy fro planking, just need to torture the planks at the bow and stern so far.
I have also fitted some doublers at some places along the keel to give the planks more surface to stick to, mainly at the upward sweep of the bow and at the stern where the keel rises.
Ian
-
Man That's Looking Awesome, Can't Wait To See It Finished Bud %%
-
Hi...planking can be a great adventure & source of enjoyment...& I see you are going by some of the cardinal rules.......one point to consider.... ok2
Keep progressing evenly [from both directions] toward the 'turn of the bilge'.... here is the more difficult change of directions which can be achieved by 'blocking in'.....with solid material & shaping later
Keep up the great work & keep us posted with more snaps
Oh...BTW...what is the planking material & what glue do you use............ :-)) Derek
-
Derek,
I am actually planking in 3 directions! 2 directions towards the turn of the keel, and one from the line of the main deck towards the superstructure deck.
The wood is cedar, cut from stairway supports, cost I think £20 for 4 lengths, and this is the third boat from that wood. :-))
I use this glue:
http://www.bostik.co.uk/diy/product/evo-stik/resin-w-weatherproof-exterior-wood-adhesive
Ian
-
Derek,
Your comment about cardinal rules - I was wondering what you refer to?
I plank and build in a way that I have developed and works for me.
Ian
-
Hi Ian You are doing a great job.I found these on the net might be of use to you.
John
-
Could you post the setup you use when resawing the cedar into planks? It might help those of us who want to mill our own planking in the future. O0
-
The cedar was originally in 100mm square by 1m long pieces.
I asked the woodyard to cut the pieces into 10mm thick planks, giving me 36 planks at 100x10x1000mm and 4 small offcuts.
I then used my bandsaw to cut these planks into 2mm x 10mm x 1000mm planks. So, with mistakes and wastage I got about 180 planks at 2x10x100mm.
Ian
-
Ian says.....
Your comment about cardinal rules - I was wondering what you refer to?
1) start with one plank at deck level.......
2) one plank to one side then....install a mirror reverse to the other
3) then one plank butted into the keel plate
4) progress evenly toward the turn of bilge
5) be logical as each hull design is different
These may sound simple O0 but many forget..... >>:-(... Derek
-
A few more planks fitted and the profile of the bow is starting to emerge.
Ian
-
More progress on the planking. You can see the planks working round from the keel have now met at the bow with the planks coming down from the deck. I alternate the required taper where they meet at the bow between the upper and lower planks.
It looks a mess at the moment, but mine always do at this stage :}
Ian
-
Looking good Ian, should be ready for the water in a fortnight at the speed you go :-)) Oh is that ladder in the first pic to enable you to gain access to the work bench {-)
Alan
-
Ladder? Thats my 12 inch rule :-)) :-))
-
Right then, I have now almost closed the hull, just a couple of stealers to fit in the turn of the bilges. Still a couple of rows to fit to get to the bridge deck level.
I have also cut and glued balsa into the stern ready for shaping, the bow will get the same approach.
ian
-
Looking great Ian :-)) ...the next cardinal rule is..........
Add glass fiber cloth & epoxy resin to the full internal hull surfaces between each frame x as many coats as you feel is necessry for the required strength
NB...this is prior to any external hull sanding
In OZ we have a 50 mm wide woven glass cloth that is self adhesive on one side only........works well in positioning & holding the cloth prior to the epoxy resin during the model hull building etc....Derek
-
Derek,
I can understand where you are coming from about glassing inside before external sanding. Its not an approach I have used before, I usually sand and glass externally before taking off the building jig and glassing inside.
I will give this some thought, as this hull is very different to any other I have done before, it may well be the way to go.
Thanks
Ian
-
Ian..... {-)...I suppose there must be 127 %% Cardinal rules with planking <*<........
The stresses induced into the hull when planking should be minimal if Cardinal rules 3 to 12 inclusive are applied.....so I also understand your build/planking philosophy....Derek :-)
-
A little progress report, I won the first round battle with Col. Orbital Sander and his 120 grit troops, the pics are below.
But now, I am working at the bow where the hull meets the deck. The bit above the deck - sprayrail? is a nightmare, its a compund curve. The pics show the plywood template I had to develop to get somewhere near.
Ian
-
In case y'all thought I had abandoned this project, I haven't!
Been a bit busy with other stuff, including that delftship tutorial - all takes modelling time away <*<
Anyway, had some progress, but its just sanding, filling, sanding, filling....... so I wont bore you with pics.
When the hull is somewhere near it will have to come off the building board so I can locate the position of the main deck to allow work on scuppers, ports, anchor hatches etc
Ian
-
After a session of filling sanding filling sanding...... we have this!
Springer parked alongside to give an idea of the size.
Ian
-
Looks lovely! I want one!
Such a pace you're working at too. I do that sometimes, then have big lulls where nothing happens :(
Alex
-
Hello
Very nice job.
What about your Springer : where are the forward and aft side ?
A+ Xtian
-
Spent today shaping the stern and cutting holes for the scuppers and accomodation windows.
-
Hi Ian
Hi Xtian
and all other friends of the NOSES
Until now I thought I am the first and only man on the moon...
But what I can see here... :-)) :-))
RESPECT!
Let me introduce my project:
Building is an AX102, one of the smallest BOWS in the fleet of noses (1,55m in 1/50 scale)
Start was in autumn 07 and now project grows on.
Your problems with drawings of UL are well known, this Model is a scratchbuild too.
Maybe we can complete some information here?
Ok, I'll try to upload some pics - empirically it did not work the first time...
greets
Pete
-
As I feared...
Here are some hosted pics on my own webspace
not actual state...

Pete

Your project is coming along very nicely, very impressive :-)) How does it handle on the water with the shaped nose???
Voyager
-
Very nice Peter.
What running gear do you have in her?
Also, I would be interested to hear how you have fitted the cargo deck, allowing for access to the running gear.
And, have you got removeable superstructure? If so, any chance of some pics of how you did it?
Ian
-
Hi
It runs well ;-)
Heavy wheather isn't testet at yet, but it runs well on normal ambient conditions.
There is less swell than with conventionel hull of my ABEILLE.
It looks not as sensational as the typical "dent" at midship of normal hulls, but at same speed. There are only ~3 smaller waves, probably a better degree of efficiency?
In fact, we should scale down the characteristics of water in 1/50 to get a realistic effect of the nose...
The hull is powered by 2x35W (effective power) Bühler engines at 75mm Raboesch props.
That will suffice to a upper scale speed but only less reserves to pull sth.
Be aware of the Gr...ner Voith-Schneider (as i mentioned to read above?). I've seen a Bow (about ~25kg) here in Germany with this propulsion, but it didn't run well. <:(
Pete
-in the meantime-
Oh...
Hello Ian
lets see...
-runinng gear is descibed above, that's what you mean?
-cargo deck is a "dummy". It's only a 0,5mm GFR with a under-contruction and wooden sheeting. I can lift it off complete, sealing of inner life is a level down.
- I can lift off the bridge (seldom used), and can pull out the rear wall of superstructure like a drawer (?)
let's see if I can find some pics (and to wangle this d.mn javascript upload....)
Pete
-
Ok, same story ...
If someone can help me out?
I'm using firefox (with noscript), but all restrictions are switched of.
A new window poped up, "browse files", and some secs the file is uploaded to öhh.. -nirwana?
(and what the h.ll is "hotgirls4..." ???)
anyway, no pictures here... <*<
Aft deck without the dummy and visible sealing (a kind of tupper ;-)
(http://home.arcor.de/hummelbrumm/gast/offshore/DSC_1324.jpg)
Dummy deck
(http://home.arcor.de/hummelbrumm/gast/offshore/1746.jpg)
The main engines, between 2 pumps to supply the rear thrusters
(http://home.arcor.de/hummelbrumm/gast/offshore/1332.jpg)
Sorry, can't find some pics of the opened superstructure actually.
The main winch and all parts on aft deck remain on its places. Crucifix ist devided, and I can pull out deck 1+2 with crane, FRB, secondary winch and all parts added on the rearplane of superstructure.
It's a little bit tricky, but: That's modeling ;-)
Pete
-
Lovely work Pete....and those containers on the deck look superb, very nice indeedy!!!!
I'll be watching this one closely, can't wait to see the detailing and the painting to come :-)
-
Hi Peter.
I thought I recognised your boat . I have been following your build on a different web site. Most impressed.
John

THX!
John, you're right ;-)
But i wouldn't bump this thread of Ian with my pictures....
Pete
-
Got a bit bored building the hull, so I decided to start on the bridge deck and superstructure.
The bridge looks too small, but I have checked the dimensions about a dozen times and they are right - will look better when its finished - I hope!
Ian
-
Hi Ian
you asked about the openings..
The "drawer" ...
and the remaining hole
-
Peter,
Thanks, thats a good way of gaining access, I was thinking along th e lines of lifting the bulkhead vertically, but your idea is better - more room for fingers! :-))
Ian
-
spent today on the bridge structure, think I threw away as many pieces as I fitted, devils job getting all the angles cut right!
Ian
-
WOW!
Bridge is a fiddly (?) work to do, but it looks fine, well done!
Dimensions seems to be correct- my own bridge is a bit oversized, I forgot the socket and added it later. Therefore my bridge looks ~8mm higher.
Is there any supporting/stiffening structure inside the ABS plates?
(If you want to lift off the bridge later, it would be essential)
CU
Pete
-
Fiddly describes it just fine!
There are no supporting structure yet, but there will be, probably in the form of control desks around the structure,and floors.
Ian
-
Ian,
Looking great as usual. :-))
Peter,
Nice of you to lend a hand. It's always
good to see how others have assembled things.
Aimee
-
Hi Umi :-)
Didn't you sleep sometimes?
Is there a forum around the world you are NOT involved?
I might have known it... ;-)
Did you see what Ive done to your floodlights?
(in the photoalbum, near at the end)
It's the best solution at yet. 3 sunny-white SMT LEDs + resistor are inserted from the rear side.
Tey are very flashy at ~15mA!
For the first version I forgot to paint the reflector in silver, and now you can see a "black hole" when switched of.
But that's no problem, actually there is no application to use for, and for the next time I know how to do.
CU
Pete
PS:
I've managed to go to Heemskerk next weekend, and meet the guys of SMG Ijmond and probably some of the IOS.
Shure, this will become a fine meeting :-)
-
No progress to report folks - been working stupid hours and will be till the end of the month, hopefully I will be able to re start then.
Ian
-
Ian
Im not one to read so im afraid i havent read all on here.
ut im so impressed with all the pics, she is stunning
What a challenge and hours you must have put in
Great job :-))
-
Back to it at last :-))
Spent all day today building wheelhouse control desks - not much to show for a days work, but they were fiddly, and I had no detail plans, just outlines, so just made 'em up as I went along.
Ian
-
Ian,
Wonderful work - compared to my progess on less detailed work on the wheelhouse of my Anglian Sovereign, you have been working at light speed. All power to your elbow.
Doug
-
Wow... Nice work...
Now about lighting... %%
-
Thats the sort of thing I am working towards, Umi, how did you do it?
Ian
-
Thats the sort of thing I am working towards, Umi, how did you do it?
Ian
Worked them up using renshape.... Styrene would work also(left).
I then made a mold and clear cast them with the LED inside.
:-)
-
Went out to the garage this morning to look at yesterdays work and discovered I had made one of the control desks wrong handed - made it for the port side, should have been starboard doh!
So, remade that, then went on to some more indoor furniture, then some external fittings and started the mast.
Bear in mind its all dry fitted at the moment, hopefully it will look better when painted and stuck properly.
Ian
-
Looking good Ian, :-)) my, you do like models with lots of windows in them :}
Looking forward to helping you launch it, be another launching trolley I suppose , hope this one doesn't float like the last one %%
Oh, hope you are going to make cushions for those seats in the bridge ;)
Alan
-
Launching will be a while off, Alan, time for you to build your muscles :-))
Cushions for seats? This is a working ship, not a liner, blooming crew should just be thankful for seats!
Ian
(working on a sinking launch trolley when I have a mo!)
-
Very nice, I feel like taking seat in one of those chairs and head for the horizon! Again an interesting subject and very nicely built.
Hama.
-
Great work Ian!
I'd never had a thought about buildiing the inside of the wheelhouse.
But when I see this ... :o
Go on!
Pete
-
Can anyone help me by identifying what colour these lights should be? And under what sequences they should be lit.
The pic is of the Bourbon Orca, and shows the forward face of the mast,
Thanks
Ian
-
I am pretty sure the six outside lamps are the Red/White/Red limited
manueverablity lamps... then the three white at the center top, under the radar, and low...
:-)
-
About your casts Umi, where abouts in the monitor have you put the led when you cast it? and how do you support whilst pouring?
-
At last, I have got back to the Orca, but, alas, it will be shortlived - xmas and all that!
Anyway, I have been installing control desk lighting using fibre optics - i think its worked out ok.
The pics are just a little blurred, and 2 a little dark, but I hope you get the idea.
The last pic shows the workings - 3 led's each with a foil tube, fibres stuck in the end and all stuck with cyno - as suggested by another mayhemmer, sorry cant remember who.
Ian
-
Excellent, we now have an expert on fibre optics.
Can see how you fix them at the power source Ian, how do you fix them at the other end. Do the fibres protrude slightly on the instrument board ?
Where do you obtain the fibre optics, is it the Component Shop ?
-
Very nice Ian, and just in time for Christmas, you will not have to buy a tree now :-))
Pleased that the fibre optic expert is in our club :-))
Alan
-
Expert? me? I think not!
Cant remember offhand where they came from, they are a sample kit, I will find out and let you all know.
At the desk end, simply drill a hole to suit the fibre, thread through and a touch of superglue about 2 - 3 mm from the fibre end, pull through until the end is flush with the desk and allow to set - simples!
Ian
-
Here is the website I got the fibre optics from:
http://www.lite-tec.co.uk/index.htm
it was a sample pack, but I cant seem to see it on the site now.
An alternative would be to buy a cheap fibre optic lamp or xmas tree and cut off the fibres to use - scissors do the job ok.
Ian
-
Hi
sample pack is here:

Pete
-
Well, its been some time since the last update, not a great deal done, but what has been done was fiddly.
Here we have pictures of the structure above the bridge, along with the mast. All 7 lamps on the mast work - LED's. I used alarm cable for the wiring and just managed to run it all inside some plastic square.
Next job will be railings around the bridge top, radar domes and ariels.
Ian
-
Looks great, It maybe slow progress, but it's nice to see
an update to your progress. :-))
Sure you don't need some tiny radars? %)
-
Hi
there's only slow progress here in south germany
( some new chain rollers and starting with the anchor winch )
But there is a big footstep for the community of BOW builders ;)
One of the leading german ship model magazines publishes an article about a BOW in its actual peridiodical:
http://www.vth.de/zeitschriften/modellwerft.html (http://www.vth.de/zeitschriften/modellwerft.html)
(Sorry, this link only works next 4 weeks, it directs only to the actual magazine)
Think you know this NOSE %)

This thread is a real eye -opener. very impressive :-))
-
Here is another supplier of Fibre Optics.
Its aimed at model rail modellers but applies just as well to marine use.
www.branor.co.uk/products.htm
This chap also has a Youtube video showing how to do the lighting. Even how to make model strip lights.
Find it here:- http://www.youtube.com/watch?v=6VM3dmutMWw
Looks very interesting.
Cheers

Anyone got any suggestions for how to make the radar domes as shown in this pic?
Ian

What picture Ian ? {:-{

Would it be possible to do something like John bluebird did on his whaleback's turrets. {:-{

What about deodorant aerosol/roll-on tops/lids?
-
Been scanning around for those, swmbo must be hiding them >>:-(
Moulding as in Bluebirds thread is an option if all else fails.
Ian
-
Give the kids some of those children eggs with chocolate in the shape of an egg.
The surprise inside it is hidden in a plastic bin, and that plastic bin is perfectly suiteable for this radome's.
I hope they also are available in England, but here in Holland they sure are for sale.
Greetings Josse
-
Give the kids chocolate - no way, I'll eat it myself :-))
Thats worth looking into, thanks.

Anyone got any suggestions for how to make the radar domes as shown in this pic?
Ian
How about the plastic tubes cigars sometimes come in. They have a rounded top like the domes.

I used some tube end caps, but sorry, in meantime distributor is down.
For small ones, you can can also use the caps of menthol-sticks (to inhale and stick into nose)

21 mm, 15mm and 8.5 mm diameters
Ian

Depending where you live don't forget about the toys that you get from the kids bubble gum machine that have small toys in those little plastic containers. One side of them would also make a great dome as well. I have also used some ping pong balls as well.

hi
you can get the domes from here http://www.marinetic.de/index.php?cat=1765 but i dont know if it would be a bit far away from you!?
keep up the good work with your model
regards
me3
-
Thanks for that me3, they look good, but at 13 euro for a 15mm dia one - think I will persevere with my own.
Anyway, I found a couple of cedar mothballs just the right diameter, 2 coats of sanding sealer, chamfered the inside of a bit of plastic pipe, stuck em together, chucked a bit of filler at them, sanded and painted, and voila....
-
Then I moved onto the rudders, just for a change, started with a brass plate, soldered to a brass rod, cut a groove in 2 pieces of balsa and glued them to the spade, sanded a profile on the rudder and glued a bit of thin ply on the top and bottom of the rudder, and voila...
These will be covered with thin glass cloth and epoxy at some time in the future...
-
I have also progressed the superstructure a bit.
Took lots of time to clean up the superstructure, adding filler and sanding off.
Cut out a deck piece and fitted the control room deck in a cutout, then had to make lots of fiddly adjustments to get the outer piece to fit on it.
-
Hi
Your bridge looks great! :-)) :-)) :-))
And a good solution for the radar domes!
Pete
-
Hello,
Whooooooooo! Great job!!! :-))
Kénavo, Philippe!
-
If I may, another technique for producing ovoid domes.
You take an egg that you cut the mini disc drill. You resins inside, then you add any base that you paste. A few chews to join. After painting, the effect is guaranteed.
Advantage, following the animal, you have several egg sizes. It'll just go to the corner grocer provided with your Caliper to find the egg that has the proper diameter. Beware the grocer may take you for a fool ... %% {:-{
Kénavo, Philippe!
-
Great idea Philippe, and you get breakfast out of it as well :-))
-
I have been working on the driveline at the moment.
These will use 50mm MMM nozzles, and home made shafts and bushes.
Pictures show, in order, the slot for the mounting drilled ready for cutting and opening up the slots.
Next shows a wooden wedge I made to sit between the hull and mounting to align the nozzle properly, then with the mounting dry fitted in the hull.
Then we have a side and end view of the nozzle and shaft dry fitted. You will see I use a plastic disc in the nozzle to align it all.
Then we move on to the prop shaft components. The bushes are made from leaded bronze, the tube is brass.
I haven't finished the 'P' brackets yet, as I need to get the props in place to determine the angles I need to fit the bracket.
Finally we have the tube with oiling tube fitted. To do this, I silver soldered a 25mm length of tube to the prop tube, then drilled a hole in the main tube and cleaned it all out. I used a 25mm length because it allowed me to get a drill down to drill the prop tube. I then slid a longer piece of tube over the first length and soldered it in place. At this point, I used a lower temp solder so as not to melt the first soldered joint.
This tube length was cut to bring the end above the water line. Finally, I turned a small aluminium plug to push fit in the oiler tube just.

Today I have been fiddling with the drivelines, the pics show how I set up the shafts parallel. Everything is loose fitted at the moment while the wooden wedges between the hull and korts dry.
Ian
-
hi thanks i have downloaded it and i am going to try and get my head around useing it
-
Today, I made two motor/shaft alignment tools. In the past I did alignment my eye and short ruler. This time I thought I would be a little more technical about it. The tool is simply a length of brass, drilled each end for a push fit on prop shaft and motor shaft.
The next job will be to glue in place the shaft tubes.
Ian

Spent some time today on the main deck and winch deck.
The pics show what I have done. Whilst in the process of doing this, I discovered a mistake in the build. The pic with the arrows shows a space between decks that would suit only vertically challenged people!
So, what to modify? Add a plank above and raise the deck levels? Or remove a plank along the main deck. After measuring all round again, decided that the best (only) option really was to remove a plank along each side of the main deck. This took some time, as I also had to lower all the frames to suit. Anyway, got it done and you can see the difference in the following pic.
Ian
Doh! managed to load one pic twice!
-
Got back to it today, and realised that the main deck wasnt the correct width, so, out with the saw and cut off some of the frame edges.
The first and second pic show after modification. But, I then realised that the sides above the main deck carry through under the next deck Doh!
So, out came the saw again, you can see in pic 3 the mods I made.
Pics 4 and 5 show the area within the bow, with a couple of platforms in place for batteries and electronics etc.
Ian[code][/code]
-
Before going any further with the decks, I thought I should make the winches, the thinking being that decks are easier to modify at a later date if required than winches.
Anyway, here are pics of progress so far.
Ian
-
Very nice Ian

Your making a great job of her Ian those winches really look the business

I didn't think the main deck was too narrow...
I did think that the side passages alone the deck were too wide though... :P
Looking good Ian... :-))
-
And back to the Orca after steam engine time!
Anyway, I have fitted the 'p' brackets, mounted the motors and put in the rudder tubes - all routine stuff, so I wont put in pics of those.
I have been wondering how to get access to the motors and shafts etc through the main deck, eventually, I came to the idea of using re seal-able food boxes recessed slightly below the deck, and fit a removable deck over the top.
The pics show the progress:

Hello.
After reading your building report I am surprised about your solution to create a watertight deck.
I new another modeller with the same solution.
But I will give you my solution.
I made all decks of plexy glass, perfect to saw,and glue.
In this deck I made a hatch.
This hatch you can tape complete watertight with isolation tape.
Above this plexy deck is the falch deck this is made of 1,8 mm print plate.
At the print I glued the wooden deck.
If there are any troubles under need you only take of the falch deck and you can see trough the plexy deck all what happen under need.
It´s simple to made and very use full.
Please look at the photos.
gr Leen, (model Maersk Master)
-
Hi Leen,
What did you build your finish deck on.
It looks very thin, but also very rigid.
Aimee
-
Leen,
Nice solution, have to admit I hadnt thought of that.
Ian
-
Hi,
Realy good job!!!! ok2
Nice and clean construction, i like it... :-)) :-))
Kénavo, Philippe!
-
Hi Aimee
The falsch deck is made of printplate 1,8 mm.
Print plate is very hard en get good shape.
That's importand because the wooden planks are glued at this print plate.
Till now I works perfect.
The plexy deck and hatch construction is copied many times.
It's to simple explane, but it works perfect.
Do You get the time to meed us again in Guterloh?
gr leen
-
Dont you just hate building model boats?
Paint hardly dry on the last one, and here I go again! %% %%
Ulstein, the builders and Bourbon wouldnt let me have a linesplan, so I designed the hull myself.
Thank you to those who let me have some pics and information - you know who you are.
Anyway, here are the frames pasted onto plywood ready fro cutting out.

Hello Ian,
these resealable boxes are famouse for not taking any glue. How do you get the hatches watertight if you can't take any glue?

Dear possible would you send to me the plan of the vessel Bourbon Orca?
Looked at several sites and so far not succeeded. I hope you send me. Thanks.
-
I dont have a set of plans in the conventional sense, I designed this hull in Delftship, and then worked on the fittings from photographs taken from the web and the Bourbon website.
An update on the build, I have now been able to restart this project and have epoxied the inside of the hull, and started construction of the handling crane, pics will follow soon.
Ian

Careful Boatmad...that looks like a Chinese full size tug shipyard O0 {-) {-) {-) {-) >>:-( <*<

I would like to suggest to the admin that this post is worthy of the 'masterclass section' a very diffident model, high in detail very nicely done looking forward to the finished product. :-))
-
I second that :-))
-
The consideration for inclusion in the Masterclass Section is when the model is completed, not during the build.
Bob
-
Hopefully,once finished it is assessed for Master Class ,as this is quite a build. Very informative as well as great craftsmanship.
-
I say there ship mate that is a great idle with the containers I wish I have thought of that with my Aziz build may go back and see I can refit my Aziz with the same type of containers like. Because I still get some water into the boat I do believe it comes from the hatch..

Some progress to report at last:
Been working on the main deck crane, the main components are etched brass, the rest styrene.
Still a bit of work to do before it gets anymore paint.

Wow, Where did you get the brass etchings?
Did you lay those out and etch them yourself? They look great!

I am hoping to restart the Orca build very soon, but at the moment my right hand is heavily bandaged after an accident (modelling related) which makes things a little difficult.
Watch this space!

Change of subject slightly but still based on the X-bow design (don't want to highjack this thread).
I will be heading up to the Ulstein yard in July to take over our companies new vessel, Oceanic Sirius. Built for seismic exploration, she is the SX120 hull and will be the sister ship of the Oceanic Vega that was delivered in July 2010. A touch bigger than the B. Orca at 106m long and 28m wide.
My company is involved in the seismic exploration side of the equation whille the marine management will be undertaken by Eidesvik.
There are plenty of information and pictures of her sister ship (Oceanic Vega) on the internet if you are interested.
Cheers

Hi Ian
Fantastic build which I am following with interest.
As a complete newbie to model boat building (I'm about half way through my first project, a PT boat) I am keen to know what the material is that you have used in the construction of your Bridge. Looks to be reasonably easy to work with and gives a good finish. I'm assuming it's some sort of plastic and would appreciate your advice.
Regards
Kevin
-
Looks like plasticard or styrene as its also known.
Available as standard in pretty much all model shops. You can also source bigger sheets online in a range of colours!
All mated together using plasticweld.
Dan
-
Hi,
Dan is right its styrene sheet, easy to work with and gives a good finish. One thing I have found is that you need to wash styrene with warm soapy water and allow to dry before painting, as it can sometimes collect a bit of a static electric charge.
Update on progress, I have given the hull 2 coats of epoxy and am now ready for the next opportunity to wet/dry it prior to painting.

I suspect he's made it on CAD and had it etched.

Oh, it was absolutly brilliant (Btw. I'm the one with the blue cap and X-Bow shirt). Unfortunately I had to cease the building of my "nose" <:(. It is almost impossible for one person to transport such a big and heavy model (1,35m length, 0,31m beam and appx. 30kg of weight). Most of all I'm depended on public transport. >>:-( >>:-(
Guess I have to reorientate about the scale. Building a 1/100 little nose sounds good to me.
Meanwhile I'm thinking about selling the vessel.
I will see what I will do.
May the night be with you.

Meanwhile i got used to the thought of ceasing the work on my Beluga. I'm really looking forward to a new start. Especially I had learned a lot during the construction work. I'm sure, some mistakes i won't do again. Too bad, it was one of the first German X-Bow Models. Petes was the first. My model was No. 3.

After having a check of the hull pictures I realised there were a few bits missing on the hull, the rope guides at the bow >>:-(
So, out with the drill and piercing saw and here we have the result on the stbd side, port side yet to be done.
Ian
-
Some more work on windows and ports today. I made plastic liners to fit inside the windows and portholes in order to get a better finish than I would get with end grain wood.
I have also fitted all 4 rope guides for the bow, and the anchor stowage.
-
Before going any further with the hull prep and painting I thought maybe I should sort out the stern of this thing.
So, here are some pics of today's progress, its slow, but I have had to make up each part to fit. Hopefully, when the two sterns columns are on I should be able to make up some sort of rolled edge to go between them - thats the plan anyway.
Ian
-
looks good from here..
-
Where or how do you learn to build something like this. im a new member to this forum and ive read lots of these build blogs and the craftmanship is second to none in most of them. Ive only built a couple of speed boats because its the easiest hull to make in my oppinion but i cant even comprehend where to even start on this kind of building magnitude. :o %% <:( Are you peole real ship builders or something?
-
Mike,
I learnt as I went on. Started out with a Billings kit - Bankert, which is the only kit I ever did. Then tried a planing hull (MTB Brave Borderer) and after that various types of model - yachts, fishing schooner, riva, etc.
You have started off well with speedboats, its a great way to develop the skills needed for more ambitious projects. When you decide to try something different, you will be surprised how much you already know. If you want to try something a bit more ambitious I would suggest you try a plank on frame hull next, maybe a fishing boat - the hull form is relatively straightforward, particularly if you choose one with a transom.
"Are you people real ship builders or something?" - not necessarily, although I think many of the blokes have a marine background, which does help in understanding what is right.
Ian
-
i use to have a nikko rc boat when i was a kid but that was really a toy. now im 25 i want to get into model boating cos its something i allways wanted to do. i couldnt afford to buy a kit so i started building them. Started off with some small 23 cm models put an rc in from a toy car. Ive just finished my large scale one using proper rc stuff. I got a long way to go yet but i feel if i am going to go down this type of boat building path then ill have to get a kit. i prefer building them to sailing them tbh.

Here we have some more done on the stern. The bulk of the structure is balsa block, with ply skin. The rounded edges are a length of 25mm plastic tube found in the spares bin, cut in half and profiled to required angles.
Almost ready for a coat of primer now.

Graupner was supposed to release a 1:100 scale version, but it has been "delayed".
There used to be a photo... http://shop.graupner.de/webuerp/servlet/AI?ARTN=2165
:((
-
ok so if I am going to build one of these how to I draw the frames if all I have is some pictures to go on? I have never scratch built from a drawing like this but think I can roll with it if I can just get the dimensions of the boat and a idea of how to draw up the frame and keel.
-
Hi,
I only have my own delftship files for the model. I couldnt get anything from Bourbon or Ulstein (builders).
As I havent yet put mine in the water, I am reluctant to let anyone else have copies as I dont know yet how stable it will be.
I think HO scale will come out at about 1m long - a nice manageable size. However, I think you will find making some of the fittings at that size challenging, I know I have and mine is bigger than that.
You might want to think about this a little, cos I have built several scratch built boats - in fact, only ever built one kit, and the Orca has been the most difficult hull to build. There are some tight and compound curves on it that are challenging to say the least.
Ian

Next progress report.
I have added a little detail to the bridge deck and painted it.
Next job will be to fit the nav lights then move to the winch deck for detailing.
Ian
-
Looking like a proper boat now Ian, very nice
-
Nice to see you're keeping up the standard of excellence!
Mike

Today I have been working on the rescue boat.
I designed it in freeship and printed off the developed plates. The first pic shows the plates cut out and ready to transfer onto plastic.
The rest of the pics show the build stages as I add the planks.
I only use one station along with the transom due to the size of the thing - it was fiddly!
Anyway - this is where its up to now.
Ian
-
Hi,
Spent some time on the winch deck this week, the pics show most of the componentsexcept the crane, in position, but not yet fixed.
Ian
-
in ONE word...MAGNIFICENT !!!
-
Sure is,
Puts my 'fumblings' to shame...
Dan :embarrassed:
-
Looks great Ian, I think that puts me a full two boats behind.
%)
-
Genius, absolute genius.
I have been "off" boats for about two years (personal reasons), and just lately I have been contemplating getting back into them and thought "I had better have a look on this forum again".
Then I read this (from the beginning), and I am almost put off from starting again!! (Seriously, I am starting again).
Your attention to detail, your patience and perseverance is incredible and a credit to you.
Thanks for helping stir my interest again Ian.
Many thanks for sharing.
Kind regards,
Ron.
-
sorry. off topic here but its good to see you back on board ron :-))
-
Well, its been a while, but here we are again.
Been working on the electrics, both the power plant and the lighting.
All the electronics are action stuff, lighting a mixture of led and gow's. As you can see, its a right old rats nest of wires,and, for such a big boat, there isnt that much room in the for'd end!
Ian
-
Ian
Neatly bundled wiring looks good but in my experience, it's very difficult to see which wire goes where when things go wrong!
The "night" pictures look fantastic - well done!
Mike
-
Hi Ian
Lightning looks great!
And don't worry:
Electrics of a big model always ends in a "rats nest", I can tell....
Be shure, to keep general view and draw a small block diagram, eg.
Peter
-
Rats in your boat Ian, don't worry I'll bring some rat bait on Sunday :-))
Alan
-
Although I havent posted for a week or two, I have been sorting out little bits and bobs that needed fettling.
I have also made the auxiliary cranes that run along tracks either side of the main deck, along with the side structure the cranes run on.
-
It would be so nice to make those cranes run.... (http://yoursmiles.org/msmile/think/m1721.gif)
-
Progress inches ever forward......
Almost all the components are now stuck down onto the winch deck, and, the first of the graphics applied to the hull. No, its not on backwards, the other side is ok!
Need to order some more names, I ordered the wrong size first time..doh!
Ian
-
Looking excellent Ian, as usual.
Do you know what you are going to build next ? (http://i124.photobucket.com/albums/p8/DickyD_photos/Smileys/thinking1.gif)
-
Next build? Blimey, wanna finish this one first, its taken forever!
Having said that, I am working on something, but it's staying under wraps for the moment as I am still developing the design.
Ian
-
Sorry Ian, was just wondering what you could build next that could be more unusual than your recent boats. (http://i124.photobucket.com/albums/p8/DickyD_photos/Smileys/thinking1.gif)
-
I think I will be hard pushed to come up with something more unusual, however, the project under development is a little unusual and differs from the norm.
Ian
-
This type of hull might be a challenge

Hello
There is plan available in France for this kind of boats.
Xtian
-
Do you have a link please Xitian?
Dave
-
I have to ask French modelers intrerrested with this kind of boats (I'm tugman) this plans are sold by the SNSM (Société Nationale de Sauvetage en Mer) the "French RNLI"
I will come back soon with more informations.
Xtian
-
I have the special issue about SNSM of the French model magazine MRB with a low def of the drawing
it look like that :
(http://nsa27.casimages.com/img/2011/12/16/111216011320121909.jpg) (http://www.casimages.com)
The boat is SNS 142 La Teignouse I've googlelized a little bit and found this
an example of building in model forum
http://modelismenavalradioc.nouvellestar6.com/t4300-sns-142-la-teignouse

Still I have to found the way to order the drawings !
Xtian
-
That was quick Xitian :-))
Dave
-
Took the plunge - literally, today and chucked Orca into the external test tank.
She floats and is stable - what a relief! %%
She has 7kg lead ballast in her, plus a 12v 4a lead acid battery.
Sitting just a fraction high maybe, but there are no fittings on her at the time of the test, so, she should be about right !
Ian
-
Looking good now Ian :-)) You had better make a start on tyhat launching trolly :}
Alan
-
Launching trolley is well on the way, will post pics soon when I am sure its ok.
Meantime Alan, get working on your arm muscles - this is a heavy beastie!
-
Hi Ian
Looking really good. :-))
Now you have her wet I was just wondering about something general to models not to yours in particular.
I see you have the battery and some lead in her - I'll assume it is all as low down as possible too. If all the
weight is very low and I suppose it is often centralised too - I can see that gives maximum stability, but will
a model not look a bit rigid too? righting itself too quickly. I don't think I have said that very clearly. I just
happened to be looking at some fore and aft ballast tanks on the old Peralta ferry hence the line of thought
arising. What do you think? Do you ever move weight about?
Regards Dave
-
Here we have the trolley, complete with nose pad!
The more observant amongst you will note its angled, there are reasons:
1: so I know which is the front
2: so it wont fall off the back
3: the water at my club has a launching ramp and the idea is that the boat will enter the water stern first more or less on an even keel.
Regarding ballast, yes its all as low as possible, but not all centralised, there are some lumps of lead that go over towards the sides, evenly about the centre line. Three reasons:
1: couldn't get it all on the centreline
2: seems the right thing to do
3: real ships don't have all the ballast on the centreline, so I guess it must be ok.
Ian
-
I hadn't realised just how big she is - seeing her on the trolley - Wow :}
Dave
-
Hooray,
The hulls been wet. Keep on it Ian. 8)
I mocked up a hull at small scale to check frames.
I worry about the larger size. %)
-
That looks the business Umi - keep at it. :-))
-
Hello Umi
The L and M looks strange for the bottom part ...
Xtian
-
Might be just the angle on the frames.
-
Hi Umi
I'm happy to see this ;-)
But Xtian is right...
Maybe you have to "fill up" the L and M to get a clear stringer line between Bow and middle part.
@Ian
Have you ever thought about some air-filled wheels instead of theese small hard rubber wheels?
It is much easier to run with big wheels, even on bad lanes or grassland.
(and its more gentle to the model...)
Peter
-
Peter,
Yes, air tyres have been a consideration, but, at the moment its not a problem. I can park within 50m of the lake and its all tarmac. However, I may swap at some time cos you are right they are easier on the model even on good surfaces.
Also, they float! The frame is v light - aluminium.
Ian
-
Ian
I don't know if it would work or not maybe you can fill a portion of the tires with water. This would help some weight into the tires to help them not to float when putting the transport frame into the water. To puit the water in you would need to remove the valve from the stem put in some water and then fill with air.
Duane
-
Hmm...
That's right, they are floating....
That has never been a problem to me, cause my home club has no slipping ramp.
My trolley was buildt as a wodden toolbox. No chance to slip it into the water....

Hello
Peter this trolley looks to be the one for your "Petite Abeille" as there is the french AEM racing stripes :D
Umi you have just to wait 2 months and then the opportunity to check the hull lines of Bourbon Orca with this one http://shop.graupner.de/webuerp/servlet/AI?ARTN=2165
About the trolley. I have some heavy models with two boats around 50 kg and one 100 kg, I wil search a picture of it. I have air tyres on it (far better than hard ones) then I add 4 kg with lead block on the trolley to compensate as the wheel try to float. I was thinking to add water in the tyres but that means they are heavy for the rest of the time %%
Xtian
-
Xtian,
How do you transfer your heavier models from car to trolley and back? Or, do you put the whole lot in the car together and if so, how?
Ian
-
Hi Xtian
You'r right. Trolley was buildt for the ABEILLE ok2
But forget the hull of Gr...
The ORCA is online just ~1 jear, but nothing happens.
Umi is on the right way, to build herself hull
Peter
-
I'm sorry I have no pics of my trolley with ship on it. All the time when I'm using it I'm no more available to take pictures !!!
Tomorrow I will take some pics specialy
I use my trolley to move the models from car to exibition or to the pound and sometime to launch and recovery when there is a launch ramp. I have to unload the boat from car to the trolley.
But even my heavy ice breaker is easy movable by only one person when unloaded of course. Inside the hull just at the gravity centre I fixed a steel handle. If she's 100 kg when loaded - the hull alone is 20kg. If I want I can move it alone from the car to my trolley - Of course it's not for kids. The superstructure is removed, also the battery (car battery easy to handle) and ballast (lead block)
It is the same for my old supply and my X-bow (actually laid up as I'm working on other project) both of them are 50kg when loaded but around 15 kg when empty. With an handle at the gravity center - when the main deck is removed they are easy to move. For both of them even when there is no launch ramp I can launch them alone (I prefer when a second person is available :D) Then when afloat I'm loading the battery, the ballast, the after deck and the superstructure
For the fun : At home I've my own pound and an electrical lift able to remove the loaded boats - then there is a rail on celling and I'm able to off load the boat on a "working place trolley" like a bench with wheel !
My 2 meters long 100kg ice breaker on the launch lift
(http://nsa21.casimages.com/img/2012/01/14/120114075540196052.jpg) (http://www.casimages.com)
Then the "old" supply 1,86 meters 50 kg
(http://nsa21.casimages.com/img/2012/01/14/120114075801514546.jpg) (http://www.casimages.com)
The picture of the x-bow on Reply #13 of this topic was taken at the same place (outdoor side of the place)
Tomorrow I'will show you my trolley, very simple and efficient.
Xtian
-
I was just about to post, that Xtian just hangs his ships out his study window... LoL
8)
I have seen the GR release date come go, and now change. They removed the photo a few months back.
I would prefer to build my own hull any way. Plus the 1:50 hull has the opportunity to serve as an antrieb test bed for
another builder. It is one of the reasons my Xbow has been pushed forward in my build schedule.
-
Once again we inch a little closer to completion.
I have fitted all the winch deck fittings except the rescue launch - designed but yet to be made, and wound rope onto the winches.
The main deck has some wood lining on it now, but not yet varnished.
Also done, is an anchor, a couple of buoy anchors, some stud link chain and ordinary chain and fitted the rails for the auxiliary cranes to sit on.
Ian
-
looking great
-
Well folks, thats it, finito, complete etc!!!!!
Its been a long build, at times both frustrating and rewarding. There have been times when it nearly had a premature launch - across the workshop in frustration.
All that I need to do now is work out how the heck I am going to get it in the car :-)
When the weather improves and the ice goes and I figure out transport issues I'll get some 'on the water' pics to post.
Thanks to all of you who offered help and advice - you know who you are - and encouragement along the way.
Ian
-
Looking good!
Frustrating that the water is frozen isn't it?
I'm having the same problem too at the moment, and that while I live in an area where there mostly isn't anything like frozen water or snow, but since about a week ago the water here froze too, and there is also snow.
Greetings Josse
-
Ian
She looks magnificent! Well done. Like you, cannot wait to see her on the water.
Mike
-
Excellent Ian, really nice and up to your usual high standard.
The maiden voyage should be interesting, dont forget the photos.
Only one problem now, what are you going to do next.
I think you have always had a build on the go since you joined the forum so you cant stop now, think of your fans(http://i124.photobucket.com/albums/p8/DickyD_photos/Smileys/tumb.gif)
-
Looks good Ian, Im ready to give a hand at the launch as soon as the ice goes. :-))
Alan
-
, thats it, finito, complete etc!!!!!
Humm...?
You may be the first modeller who says: END! ;)
(For eg. I can see a emtpy davitd on left side... ; :P )
But the guys are rigth: She's great! :-)) :-)) :-))
Long work to go, but result it's worth!
Thumbs up!
And tell us about your secret new projects ;-)
Peter
-
Great Build Ian. :-))
Something still seems odd at the stern ramp, I don't know if it is too short, or it's angle, but
I certainly can't quibble about a finished model ready to launch.

Aimee
-
Thanks for the comments guys and Umi.
> Dickyd - I have a plane to finish now, while I work out the details of the next boat.
> Peter - you are right, they never really end. As for the empty davit, I have a design of a fast rescue boat under way which I hope to get vac formed at sometime soon.
As for the secret project, I could tell you, but I would have to kill you, so, I guess its just wait and see.
Dont get your hopes up though, its not in the same league as the Orca, but I think it will be interesting.
> Umi. I struggled quite a bit with the stern ramp, I made the mistake of leaving the design of that until I had built the hull, which limited what I could do with it and still stay within the overall scale dimensions. So, really its a bit of a compromise, but, I think it looks ok and that's really all I am bothered about.
:P to rivet counters.
Ian
-
Don't kill me !!!
(every modeller should have secret projects ;-)
rivet counters?
LOL !
We call them the same in german!
greets
Peter
-
Wonderful model and workmanship.
-
Very nice indeed Ian. :-))
-
Beautiful Ian...............I remember you coming down to my house for a chat, and telling me you'd had no luck with the builders, obtaining plans for the boat........................
you didn't need them.....it's a fantastic build, and I hope you have as much fun sailing her as you did building.
will you be bringing her to Blackpool in October...she'd be a show stopper.
neil.
-
Coming down to your place was a pleasure Neil, though I have to admit you managed to scare me off making a mold and fg hulls! I decided to stay with what I know - wood!
As for the Blackpool show, I'll have to wait until nearer the time to see if its possible.
Again, thanks for the comments fella's.
Ian
-

I'm sorry about that Ian. didn't realise that.
my apologies....she does look beautiful though.

-
Neil,
No need to apologise, I know my limitations - I think!
Ian
-
Orca had her maiden voyage today - at last.
It was a perfect day for it and she behaved brilliantly. The trim needs a little attention, but its not far out.
She is hugely overpowered but thats not a problem - better looking at it than for it! The pics with a bow wave are at a little over half throttle.
The wake pattern is interesting at scale speed, its almost flat as it runs down the hull.
Overall, I am well happy!
(excuse the picture quality - I am no photographer)
Ian
-
Hello
:-)) Very nice but ... where is the Champagne bottle to celebrate this first sailing ?
The pictures are good ! What about running backward, not too much water on the deck because of the roller configuration ? I've seen that on the real ship many time this twin roller system was in up position when the ship is manoeuvring
Xtian
-
That last picture is better than good - it's even got a seagull just as if on cue. :}
Dave
-
Dave,
You have no idea how long I waited for that seagull %)
Xtian, running backwards is ok as long as its slow. The champagne was drunk well before the pics were taken - hence them not being straight!
Ian
-
what a fantastic build Ian , and what fantastic pictures you would think she was the real thing looking at the photo's well done
-
Fantastic Ian ! The end of your model is nearly close, Do you think it was a hard construction ? and in a near futur, will you publish your plan for model boat maker in a magazine?
Encore Bravo .
-
very nice Ian - congratulations!
-
She looks magnificent. Well done Ian!
Mike
-
Another nice one Ian, how are you going to top that ? (http://i124.photobucket.com/albums/p8/DickyD_photos/Smileys/drinking25.gif)
-
Thanks fore the comments fella's.
DD - good question, what next. I have a little project under development at the moment, nowhere near as ambitious as the Orca, but its something new that I am not aware of being done before.
Gonna keep it under wraps for now until I can get a prototype in the water for testing, watch this space.
Ian
-
Fantastic Ian ! The end of your model is nearly close, Do you think it was a hard construction ? and in a near futur, will you publish your plan for model boat maker in a magazine?
Encore Bravo .
This was the hardest build I have attempted so far and the one that came nearest to getting a hammer through it in frustration. Having said that, it has also been the most satisfying for me, particularly after the maiden voyage which proved my hull design was ok - that was a relief after all that work!
I have no inclination at the moment to release a set of free plans.
Ian
-
Very impressive presence on the water. Well done on a great build. :-))
ken
-
Great model and great pictures! Do you think you will test her in some waves?? Would be interesting to see if she handles like the big ones with her design bow.
Thanks for showing, can't wait for your next build.
Hama
-
hi there Ian
As the Cornish say a proper job lad it looks really swell on the waster and worth all the effort you have put into it. One of the good things about putting a build like this on Mayhem is that you can have a look right back to page 1 and where it all begins and read your first postings :-)) {-) {-)
and just look at it now :-)) :-))
aye
john
-
That looks super on the corporation pond Ian. Very well done indeed. I hope to see it in the flesh one day.....I suppose it'd be more likely if we turned up more often :embarrassed:
-
Excellent build Ian she really looks impressive on the water. :-)) :-))
-
Hi Ian
I must say your boat has turned out very very nice. Great job
john
-
Fantastic! has a really grand and dominant look about it.
Congrats on a great build of a very difficult model, I don my hat to you Ian,
Regards, Tony.
-
I am very surprised that no one has produced a commercial hull for this type of vessel yet, I think there would be a lot of interest.
-
Hello
It's a project with Graupner since many months but always postponed, now its for June 2012. Not sure but it looks to be a small 1/100 {:-{
http://shop.graupner.de/webuerp/servlet/AI?ARTN=2165
Xtian
-
I think it will be a RTR from Graupner Xtian. I think I would prefer to buy just the hull and scratch build the rest. :-)) :-))
-
I can now reveal that there will be a fibre glass hull commercially available within the next couple of weeks. I have been working with a partner for a few months to bring this out, it has been produced from my drawings, the plug was cnc machined to ensure proper reproduction. The scale is 1:72 so it will be the same size as mine.
The intention is to launch (get it?..launch??) the hull and possibly a bridge structure at the Nationals show in Leicester, but that is to be confirmed in the next couple of days.
I have been waiting for the maiden voyage to confirm hull performance before going public on this.
Ian
-
I will certainly be interested in a hull Ian.
Put my name on the first one off the production line. :-))

Hi Guys
I read somewhere recently, and I think on a Bourbon Orca thread, somebody wanting a better view of the capsized Bourbon Dolphin.
The link has some footage towards the end (2min 15secs>) that is closer than the coast guards released picture (at least it's better than the one I saw)
Dave

Hi Dave,
the ill-fated BOURBON DOLPHIN, which after the release of the findings of the Norwegian commission report (http://www.regjeringen.no/pages/2061386/PDFS/NOU200820080008000EN_PDFS.pdf) investigating the tragic loss of ship and eight lives, must have left a noticeable dent in the reputation of the operators Bourbon as well as the builders Ulstein,
in fact wasn't of the X-Bow type but a pretty conventional AHTS design, as her builders were strangely eager to stress before the investigation commission, what can only be perceived as an exculpatory anti-advertising statement.
However, her builders obviously must have planned to deliver an X-Bow version based on the same particulars and hull lines of the A102 BOURBON DOLPHIN, which they branded as Ulstein AX102 type.
Yet, as far as I know, an AX102 has never been commissioned.
I made a wild guess at both versions' hull lines (as can be seen in this posting (http://www.rc-modellbau-schiffe.de/wbb2/thread.php?postid=272972#post272972)) on the grounds of above mentioned and highly interesting report which contains besides other technical reference a GA drawing, albeit of poor picture quality.
I suspect that the stern of my lines isn't quite correct though.
For once the flare angle of the stations/frames at the stern must be much steeper and exhibit an s-shape almost forming a concave (from below) tunnel-like trough.
Second, the skeg is probably too narrow since it must provide sufficient space to engulf the stern thrusters.
That's why I am also very keen on seeing dry-dock photos of the sterns of the typical Ulstein AHTS designs.
So if someone could provide them or knew a link where to find some I would be very grateful.
I too have planned to get my hands on the hull lines of BOURBON ORCA (i.e. the AX104, successor of the never built AX102) sooner or later which I will post in my thread when done.
-
Oops, sorry, I almost forgot to mention what a superb model Ian has built from scratch. :-))
It looks absolutely stunning on the photos he has released of its first lake trial.
I envy him for this achievement.
-
Hello Deadwood
I do not agree with your conclusion about dent in the reputation of Bourbon Norway as well as Ulstein. One of the main reason of this accident is the choose from the rig master of a non adapted ship for the job. Normaly the larger and powerful AHTS should be at the end of the line and smaller help as chaser. Here with the Highland Valour it was the opposite, then the Dolphin had the unfortunate quality to be the best manned at that time and the Rig Towmaster choose her as leader. Anyway there is some strange things with the Dolphin as so many power and big winch for such a small vessel.
About the AX102 versus A102, there is no real connection between this two types excepted the number 102. You can see AX102 is only 140 tons bollard pull instead of 200 tonnes for A102 as opposite of deadweight 2800 tons for AX and only 2500 for A102 In fact the ratio of the A102 is quite crazy but the one of the AX is ok.
Then as you can see the first Xbow was an AHTS but no mor built since that time. In fact AHTS don't need this hull. The Xbow hull is needed for pure supplies and of course seismic and construction vessels.
Then Bourbon Orca is a testbed for Ulstein Xbow, Odim and azimuthal props, and then she was paid not only by Bourbon. From this experience it's appeared that Odim Safe Anchor Handling System (twin roller) is mostly a viewed as gadget and the azimuthal props is not adapted for the job as too much power lost.
The Bourbon Orca will certainely stay alone of this kind.
When you said AX104 is a successor for the AX102, it's not thrue. It's just another ship more adapted for the job with regular propulsion and stern roller, even so, the xbow hull is not a real need for operator.
I've seen your hull version, it still work to do on the bow or like Peter, when your hull will be finish you will need lot of sculptural work with putty to be closer to the shape. Don't forget that a modern hull must be made with developable surfaces then even on the rounded xbow you can visualise that the surface is formed by moving a straight line in space this is in fact a multifocused conic surface. This not the case on your drawing but in fact Deftship is not adapted for this kind of work.

Hi Xtian
many thanks for your profound reply to my indeed weakly founded posting regarding my remarks to the BOURBON DOLPHIN (BM) capsizing incident.
In defence of my probably mostly misguided conclusions I can only say that they are based on my layman's interpretation of the Norwegian Inquiry Commission's report that I referred to above by URL and that I have to admit only have found time to read superficially so far, bereft of any expert knowledge from professional experience in matters of Offshore shipping and operations, left alone of any knowledge about the standard procedures and best practices of so called rig move procedures (RPM) or mooring anchor handling of these deep-water semi-submersible structures in particular.
Hey, I'm not in that offshore business and earn my living as a humble Unix/Linux sysadmin with no affiliation to the shipping/shipbuilding industry whatsoever, and some 300 kms inland away from the shores and possible areas of any maritime activities overhere in Germany.
But as I found out meanwhile by coming past the "Ships and Oil" website, even the panel of members of said commission who I would assume to had been recruited from the maritime industry and with a long standing background expertise in that field designated in their CVs, are from a different point of view (interest) doubted to have assembled sufficient anchor-handling expertise to satisfy the needs to pass a justified verdict.
...
The Royal Commission report extended to 208 pages without appendices, and was hampered by a lack of anchor-handling expertise amongst the Commission members.

As for my DS drawings, I am too aware myself of their deficiencies.
And it is not at all surprising to me that they may lack any developable multifocused conic surfaces.
But I ask you in all due respect, what kind of experience and ideas are we exchanging in this forum after all?
Are we supposed to construct and build real ships from our plans that amongst many other requirements they must meet are required to be produced in the most economic and effective fashion?
In my humble opinion I believe that the main requirement for a scale or semi-scale scratch boat modeller is to come visually as close as possible to the scaled down original vessel.
I can imagine only very few people being able to spot non developable surfaces on a model boat.
Besides the non fit for real ship construction under economic constraints hull lines that DS (or more rightly I as a mediocre user of DS) is able to produce, I dare to even claim that the meassured deviations from the designers' original lines plans if one made a model of both and towed them in comparison in a towing tank wouldn't be that significant in the end.
One also has to acknowledge that the models in the scales we model boaters usually prefer are immensely overpowered in relation to their originals due to the so called scale effects resulting from not correctly scaled down viscous effects.
So we need not fear unlike real world shipyards any penalties from their contractors should we miss a contracted max speed during sea trials.
Finally, if I take a look at some of the distributed model boat plans (e.g. that of PACIFIC BUCCANEER from the UK model plans service) which sometimes look as if drawn by hand (without the aid of rulers and templates/curves/spline) with a thick felt or marker pen, I must conclude that freely usable programmes such as DS are a huge boon to the scratch model boater who lacks any copies of lines plans which is often the case of very modern vessels such as those of the offshore fleets, and that they at least produce comparable results.
What years ago had cost days or even weeks of work, i.e. lofting hull lines by hand, is thanks to DS and similar software a matter of a few hours which could be even done by the "road worrior" on a laptop while under way.
However, I do miss the possibility in DS to insert standard graphical primitives such as circles, ellipses, parabolas etc.
That's why my bilge radii don't look that convincing when viewing the midship section.
But as said, on the model that should be hardly conspicuous.
Furthermore, are we commonly applying the plank on frame (POF) method where it is inevitable to do a fair amount of sanding and filling.
I assume an activity that we all loathe.
Btw, today I posted another DS exercise on an AHTS hull (http://www.rc-modellbau-schiffe.de/wbb2/thread.php?postid=274273#post274273), though this may have relatively little in common with the original vessel.
Have a nice Good Friday and Happy Easter

Hello Ralph
It's nice to see that some people far from sea and shipping industries thanks to computers enjoy and are able to manage a hull form for scale model building. Here in France there is a man very involved in the production of modeller drawings, not AHTS or OSV but big yachts !
I'm naval architect from school, my grand father was also naval architect and I learned hull form drawing with him when I was young (paper and pencil and eraser ! ) I'm not here to give my CV but from many sides I'm very close to navy, tugs and offshore shipping industries.
About model, the most important is the pleasure and the satisfaction of the modeller himself then if I said some thinks about your xbow drawing it's just to help. It's hapen some time that the modeller don't care about the real ship detail and just want an "inspired" model some other are able to put a hull in the fire place because of a small wrong detail... Of course most modellers are more or less between. In fact on a forum like here it's not easy to know who's on the other side of the screen.
As you can see on reply #13 of this post, I've made a Xbow hull for friends, I have some compagny drawing for Bourbon Orca but my hull is not fully simlar as my friends was interesting with construction vessel. Anyway the hull form with multifocused conic surface is respected.
I've also made one hull for me ... just in case ... in the future ... Actualy I'm on other projects and my Xbow hull is in the granary.
I fully agree with you when talking about modeller drawing which sometimes look as if drawn by hand with a thick felt or marker pen {-)
Happy Easter to you A+ Xtian

Hello Xtian,
It had escaped my notice that you already had built a mould for an X-Bow model because I joined this thread quite late, almost at its fade out phase.
So I had to scroll back to mentioned posting #13.
I am deeply impressed. :embarrassed:
Your work looks very professional indeed, far beyond my scope of abilities and facilities.
It looks to me almost as if you were working in a ship model basin.
On the photo where you presumably watered your hull first time it looks to me as if this was done in a trim basin of such a test facility.
I know that towing tanks
(well, the few that remained in business, as CFD is catching up and ship building in the western industrial nations nearly driven at the edge of extinction)
employ professional boat builders that produce their test scale models,
of course because of mentioned viscous scale effects at much larger scales than us mere mortal modellers, viz. the largest scale towing tanks' cross section and depth allows, often models of some 7-8 m in length.
My personal model boater's horizon is pretty much restricted by my limited abilities, comprising craftsman's skills, capacity of my model yard, poor and frugal furnishing with tools and machines, and last but by far not least, my desolate, almost precarious financial situation.
And, not to mention of course, by a this hobby violently disapproving spouse who is haunted by her cleaning compulsion and hysteria/phobia for dust and dirt. <:(
May I ask you what software you are using for hull lofting?
You may probably know, is there any such software available that can be run on a Linux computer?
I haven't found such so far, apart from FreeShip/DELFTship which though compiled for the M$Windows OS can be run rock stable under the WINE emulator,

The great thing about Mayhem is that everybody who actually takes part brings something to the table.
Thanks lads.

I can now reveal that there will be a fibre glass hull commercially available within the next couple of weeks. I have been working with a partner for a few months to bring this out, it has been produced from my drawings, the plug was cnc machined to ensure proper reproduction. The scale is 1:72 so it will be the same size as mine.
I have been waiting for the maiden voyage to confirm hull performance before going public on this.
Ian
Cat is out the bag now ...
Guys, the hull will be available from Clyde Model Boats .... other manufaturers / traders have made me aware that you have been trying to find the source.
We did have a small version of a Clyde X Bow at the Mobile Marine Sow in November last year and will have the 'full size version at the Mobile Marine Show in May (19th ) this year.
It Is My hope that we will be able to sell the Clyde X Bow at the National's Show in April this year.
Just to get you interested i will share a pic of the trial cnc plug with you...
Regards
Kim

and I'd like the second O0
I think you're going to need a bigger notepad Ian
Regards Dave
Then I'll take the third!

The plug looks great Kim, I think you will have quite a lot of interest.

I will be taking the Orca to the Nationals show on Saturday, so, if you are there, come and say hi.
She will be on the Clyde model boats stand.

And very nice it was to see it in the flesh Ian - a lovely job.
pity I just missed seeing it in the pool.

Here is a link to a video clip taken yesterday.
Grossly overpowered, but thats good.
She spins in her own length with the aid of a P94.
You can hear the rather noisy bowthruster at about 37 seconds in.

Hello to all.
I put a bit of time to look at the post.
It is a very beautiful Director, and the navigation is superb.
There are you he news of the commercialization of the fibreglass hull,
and may be a photo plate kit cut metal parts to make the detaillage.
Of v ur future construction online I will be among others to follow him.
Bonjour a tous.
J'ai mis un peu de temps pour regarder le post.
C'est une trés belle réalisation,et la navigation est superbe.
Il y a t'il des nouvelles de la commerçialisation de la coque en fibre de verre,
et peut etre un kit de planche en photo découpe des piéces métalique pour faire du détaillage.
Dés v otre futur construction mise en ligne je serai parmi d'autres pour le suivre.
