Bourbon Orca
« on: June 09, 2009, 10:01:46 PM »

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,

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?

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

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.

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.

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





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

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

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.

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?

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.

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.... 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
