Funnily enough, I tried to make an RC speedboat Hull in the same way a few years ago. In my case the foam shrank over time, which was disappointing.

Interesting. Do you think it was the water or sunlight that caused them to shrink ?@@Del350K4

@@ScaleMeDown I rather suspect that it was sunlight. If you cut or sand expanding foam, compromising the "skin" that forms when the stuff goes off, it seems to be more vulnerable to UV damage. I think it needs a stout outer layer, as these floats have, and I should have incorporated similar internal stiffeners, too.

Hello! Great design man!! It's possible for you to share the 3d models of the mold? So I can print one to try

Nice, but way too complicated for what it is. Sometime between the late 70s and early 80s I hot-wire cut floats out of foam cores for my RC model airplane at very low cost and in very little time. I did cover them later with glass fiber + epoxy, though. h.

Hot wire cut floats would have also worked well. Need to surface them though = lots of sanding

Great idea and presentation! Since you already have the molds ready... I'd love to see how one outside layer of thin fiberglass would improve the durability and surface finish.

Brilliant idea - and would probably avoid the need for any filler

@@johntreble6049 A hollow fibreglass float will work, but will be prone to filling with water / sinking if a split occurs due to hitting any floating debris or an imperfect landing. From previous moulding experience, will probably end up heavier too if sufficient fibreglass is used to remove the foam infill
