Floatation compartments

[erbinsky]

Hi all ; I'm building a 16' stitch and glue canoe . The plans I'm following show the floatation compartments being airtight sealed by a bulkhead and the deck. A fine idea if you can be sure it's 100% waterproof. I'm not sure my building skills can garauntee that. Would floatation foam give a similiar amount of displacement? I've never used it before , how does it work and how much would I need? Thanks...Jeff

Our pour in place foam is closed cell so will not absorb water even if you do get a leak, it will displace about 60 lb. per cubic foot. A 2 quart kit will produce about 2 cubic ft. so 120 lbs. of flotation. Just mix 1:1 and pour. It is best to leave the top off your flotation compartment, mix and pour about ½ quart, it will take about 20 minutes to fully expand. If you need more just add to the top, trim even with a bread knife and put the top on.
