Bass boat

[Mike Hernandez]

Hey everyone,

 

I need some help. I have a 10ft 2 man bass hunter. Its plastic. Bought it cheap. As expected, I was certain it would take in  a little water. With that being said can anyone help me figure out what I can use to fill the haul with to add buoyancy? I've seen people use foam. Does anyone have success using foams to fill the haul to make sure it floats well? Please and thank you.

I have seen spray foam that expands used to displace water in more than a few instances.  The downside is that it can be expensive.  Make an insulation guy your friend?

US Composites sell two part flotation foam, no mater what you fill it with, nothing is going to make it more buoyant than air, so why not just seal the holes letting water in. 

Two things to consider foam adds weight, 2 to 4 pounds per qubic foot.  Then you have the fun part of getting just the right amount in the cavity.  If you get too much, and that stuffs expands about 10 fold, and it will bust it like a dropped water melon.  If it can bust a fiberglass boat, it definitely will bust that plastic pontoon, and don't think for a second inside that plastic will keep it form expanding, it won't.

Don't waste you money on the Great Stuff that comes in the spray cans, it does not dry if it can't get air and just make an expensive mess.
