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.

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,

Looking good!

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?

boatmadman · « **Reply #6 on:** June 26, 2009, 07:53:52 PM »

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.

tks n rgds

Another excellent build,
How big is yours 3ns?

boatmadman · « **Reply #9 on:** July 11, 2009, 12:04:52 PM »

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

3ns · « **Reply #10 on:** July 12, 2009, 12:49:07 AM »

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.

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.

xtian29 · « **Reply #13 on:** July 14, 2009, 10:08:55 PM »

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

She's 1.8m and around 60kg when full load.

derekwarner_decoy · « **Reply #14 on:** July 15, 2009, 07:22:06 AM »

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......

...... Derek

3ns · « **Reply #15 on:** July 15, 2009, 07:26:07 AM »

Hi xtian29

Very nice

What material did you use?

xtian29 · « **Reply #16 on:** July 15, 2009, 10:02:37 AM »

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

The X1 (larger) and the X2 (medium) the middle part (without form like a cylinder is removed)

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.

xtian29 · « **Reply #18 on:** July 22, 2009, 02:28:53 PM »

Hello

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

A+ Xtian

3ns · « **Reply #19 on:** July 22, 2009, 02:55:26 PM »

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

xtian29 · « **Reply #20 on:** July 22, 2009, 03:26:37 PM »

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;

boatmadman · « **Reply #22 on:** July 27, 2009, 08:28:04 PM »

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.

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....

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

boatmadman · « **Reply #25 on:** July 28, 2009, 05:43:24 PM »

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:

boatmadman · « **Reply #26 on:** July 28, 2009, 09:37:02 PM »

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.

Hi Ian You are doing a great job.I found these on the net might be of use to you.

ZZ56 · « **Reply #28 on:** July 29, 2009, 02:52:35 AM »

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.

boatmadman · « **Reply #29 on:** July 29, 2009, 08:16:56 PM »

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

derekwarner_decoy · « **Reply #30 on:** July 29, 2009, 09:33:26 PM »

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

but many forget.....

boatmadman · « **Reply #31 on:** July 31, 2009, 12:36:11 PM »

A few more planks fitted and the profile of the bow is starting to emerge.

Ian

boatmadman · « **Reply #32 on:** August 06, 2009, 08:04:06 PM »

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

AlanP · « **Reply #33 on:** August 06, 2009, 08:18:46 PM »

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
