Closed Cell Foam is great for custom outfitting your kayak to fit certain needs. Whether it is making a custom transducer pad, carving new hip pads for your sit inside kayak, adding more flotation to your kayak, or for re-enforcing the deck of your kayak to be able to take a heavier load, the Closed Cell Foam can do it all.
First I want to apologize for the duplicate previous posts - my internet is so slow I couldn't tell the first one was sent. Today I completed installing the foam blocks into my stitch n glue canoe. It went pretty well but took a couple days while I waited for glue to cure. I used Weldwood latext contact cement on the blocks I attached to the inner sides of the canoe. For under the seats, I added a wooden frame that was screwed to the seat crossbar and glued with Gorilla Glue. The Gorilla glue also took to the foam and is holding it in place. The wood frame is intended to make sure the foam can't escape. I glued 1 inch foam on the top of the seat for floatation and comfort. I think I'll order 2 more blocks of the 2 inch thick foam to add to the bow - that should put about 450 pounds of buoyancy into the canoe and I can feel better when I get on a big lake. Its not the prettiest but I'm all for safety. I'll post photos of the install on this blog.
I bought several blocks of this foam to add safety buoyancy to a home built stitch & glue canoe. ACK could not give me a buoyancy rating for the product so I conducted my own test. I'll try to include a drawing - should have done a photo. The 2x12x24 inch block would float a little over 30 pounds in the water. I'm really impressed. I hope to attach the foam using contact cement and some strapping. The blocks I have should support about 390 pounds. I have been looking for a product like this for the canoe for a couple years. I'm very pleased w ACK's service and willingness to ship US Mail - the only affordable option where I live in bush Alaska. I am considering replacing the failing urethane floatation in my 18 foot power boat too - but need more research. Since I haven't got the foam installed yet my rating is based on the great service, good price and making available what appears to be the ideal product for my needs. Since its polyethylene I am hoping for good durability.
