Found this form from subpirates.com and thought I would share my first scratch target build. I am using the lost foam technique to make a one off of the Dockwise ship Black Marlin.
I plan to have a full functional ship with diving capability, bow thrusters, and anchors.
For my first step I made my foam cutting templates from an enlarged set of loading plans provided by the Dockwise website.
I then set out and cut out my basic blank from insulating foam using my woodlands wire foam cutter.

Oh man Boatman is going all out on his. I am not sure how he got those plans but, I think I emailed every email address Dockwise provided and got nothing. A good portion of mine has been guess work or lots of picture studying.
Well after I shaped the body I went ahead and shaped the bow and the protrusion on the front. Perhaps you gents can tell me what it is I am generally a sub builder.
-
After the bow was shaped and stern smoothed down I mixed up a batch of Plaster and filled in all the holes and pits and tried to get everything as symmetrical as possible.
-
After I got all the plaster sounded down and the boat shaped to where I needed it I coated it in tape in preparation for the fiberglass. I coated the boat in tape because I wil be using Polyester Resin to coat my boat do to its cheapness and availability.
-
After the tape was on I laid the fiberglass. I first laid a straight resin coat then followed that with a light mat then heavy mat coat. I then finished the boat off with two more straight resin coats to fill dips and holes. I am also hoping this will leave me some room for sanding it all to form.
After I was done with the fiberglass I took the boat outside a put it in my kids pool for fun. I now realize I either need lots of weight or I can make this a wet hull boat like one of my submarines.
Now for the bad part. Instead of picking the boat up I left it in the pool and went inside. When I came back out the entire loading deck was bowed upward. I think this is due to the sun heating the air trapped inside the boat causing it to expand. So now my problem is how do I get it to go back down. I dilled a relief hole in the top and set a shet of steel on top and then my welder on top of that and left it in the sun. Its gone down a bit but not all the way.
Any advice on this one guys?
-
hi the bit on the bow is called a bulbous bow. I like your build approach . You got a good shaped hull from no planes. Its a shame when these company's don't give us modelers a few simple plans. So do you intend to make a mould from the foam hull to make a fiber glass hull.

No this will be a one off. Im not putting my workmanship down but I dont think it will be good enough for a production kit. First I must test my technique then I can improve it with a future model. Baby steps if you will.
After I have sanded and shaped the hull how I like it I will cut my access holes for the equipment and scoop out the foam on the inside manually or with a bit of gasoline. Not sure on the gasoline anymore though considering the price!
Any ideas on getting the deck back to shape?
-

-
Fiberglass about 3/8" thick

Hey Nuke,
Thats looking real nice. Sounds like a faster build than mine!
I got info from dockwise, pictures and a small set of lines. They were so small enlarging bigger than A4 lost detail on the hull curves, so i used a pantograph - slow but it seems to have worked. Its not an easy hull to plank!
Here is the email address I used:

I hope to post some progress this week.

My only problem at this point is that the loading deck is warped and I am being told since I layed it up in Poly Resin that I am basically screwed. It may take alot of work to fix it in the end. I was told to start over but......... I dont know about that. I will keep sanding it down which is turning out to be one hell of a project on its own. Maybe I shouldn't have put down so many layers of resin.
Ive seen that german and his website before. TO bad its not more complete with say an email address!
