I bought a Wood Duck 12 recently and am at the point where I need to fillet the top to hull. My question is this: since it is nearly impossible to fillet and glass the deck hull seam all the way to the bow and stern, would pourable foam be sufficient to hold the bow and stern to the hull? I bought this product from the company in San Diego that sells this stuff to the boat industry for flotation. The instructions indicate that it is basically structural foam which has good compression numbers and surprisingly good tensile strength - on the order of 20 psi. I was going to add this flotation anyway, but was wondering about sealing and "gluing" the last couple feet at the bow. Thanks for your input.
