Could possibly float boat

[kwik]

its probebly stuff called blue core.... its a high density foam sometimes used in RC planes....

would be good to see, are you going to work out how much you need? or are you just gunna through it all together and see what happens?

[PedeBasher]

Well I am going to work out roughly how much I will need going across and then work my way up. The side of the hull will probably be pretty high and dense.

I am going to be looking at boat hull designs tonight to figure out what I want to shape it after and what would work best for me. Probably either a vee hull like on my jet ski or a catamaran. Both will offer tons of stablility.

id flat bottom it with a front curve just like a jon boat. will make it less tippy and help boyancy

[PedeBasher]

I think I will but also give it a small vee slope to make it a little more controllable.

So far it looks like my dimensions are going to be 8' by 4' and a half. Id love to add a cab to it, and possibly a small storage cabin underneath. I will also have a rudder and possibly have it hooked up to a steering wheel.

are you goign to somehow seal the foam? i guess i just dont understand how dense this stuff is....do you tink itll push in with the weight of people on it?

[PedeBasher]

Yeah the foam will be sealed. I might even go ahead and put a layer of fiberglass epoxy resin on it.

It shouldnt push in. The deck should be pretty thick by the time I am done. I will have a lot of foam built up in the hull.

What kind of adhesive are you going to use?

For the deck and possibly the outside, you might want to consider skining it to aleviate potential damage from beach rocks, shoes, etc. Maybe some plywood for the deck, some kind of laminate for the outside (I guess the fiberglass would work there). Once you skin foam, its dang tough.
