Gentlemen,

Say I want to make sure my boat does not sink even if it's full of
water.

It weighs 4330 pounds. Does that mean I have to add about two cubic
meters of foam somewhere? There isn't enough space for that much.

Or can I somehow take into account the buoyancies of fiberglass, fuel
tank, engine, and all the other stuff? Is there a method to calculate
things like that?

What year and size is your boat? Newer boats already are required to
have floatation. Usually it's expanding foam under the floor and in
the sides. US Composites has a good expanding foam.

Jamestown Distributers also has expanding foam made for boats. So-
Called Great Stuff can absorb water.

I would guess the foam should be "closed cell". Great Stuff apparently
isn't.
