Foam fill the hull ?

[abl1111]

I assumed that the foam technology would incorporate closed cell foam. Is this the case, or is the foam used the 'sponge type' foam that will absorb water ?

Assuming that the foam is closed celled, is foaming a good idea ? I see it as;

The Pros: more solid feeling/sounding hull. More floatation/bouyancy.

The Cons: if you have to get to an area for a repair or other reason where you have foamed - it would be a hell of a job. You would have to really think aherad as to any mods you might want to make i.e. running plumbing or electrical

Be Careful if you have never worked with two part foam. It's extremely expensive and will ruin everything it touches. Like 5200 only 10 times worse. Also it expands in ways you might not want.Use too much and it has the power to split hull deck joints and put nasty buldges in floors where it dosen't have adequate room to travel. You may gain flotation if your sinking but bouyancy is different. Adding foam dosent change the mass of the boat as it sits in the water, therefore your bouyancy is the same as before the foam. Trust me, the stuff is a pain in the butt.
