Adding flotation material under seats

I have an old Ouchita 14" aluminum. The flotation material under the seats is breaking down and blowing out.

Any suggestions on what/how to put under those seats?

Thanks

How about styrofoam blocks? Just a thought. There must be some sort of table that does the math on flotation capability relative to weight of item that must remain afloat.

Styrofoam does not hold up, exposure to weather, sun etc will make it break down and fall apart. Flotation is usually expanding closed cell foam.

Hummm. Okay, how about that spray insulation that expands while it cures? Spray it in the voids under the seats and seal it with a couple coats of marine varnish. Could be kind of messy though. This is an interesting problem.

Re: Adding flotation material under seats

I have used the pink foamboards on the floor, between the ribs. Then, put a piece of heavily varnished plywood on top.
This was done on my 16' jon boat about 20 years ago and is still holding up well.
Always kept the boat covered and dry.
If the floatation material is coming out from the seats, not sure what to do.

I have cut open one of my bench seats, added floattion on the floor and styrofoam blocks on each side of the bench.
left the middle open for storage.

However, do so at your own risk and peril b/c this does affect the vessel's floatation.

Re: Adding flotation material under seats

Spray insulation is open cell, it will absorb water like a sponge. 2 part pour in foam is expensive. I used the pink foam board, closed cell, cheap, and it works. If it is a covered area, you can also use those pool noodles stuffed into crevises. I did alot of research on this before I restored my boat last fall.
