Any time something brings people with different experiences,backgrounds and opinions, there will be a discussion. Now as far as the foam in this boat, after looking and discussing it with twisted, we're going to start pouring foam above the deck. Up in the front of the bow in front of the pedal. In the back corners, and the seat box will be filled. The stringer will prob be full and sealed. Its perfectly sealed so I think its safe to fill. Were only trying to use as much of a 2 gal kit as poss. There is a small area under the forward deck and maybe the area just behind that section. If we're out or almost out of foam, it won't get any more. Gonna drill holes in all the corners of the little bulk heads just in case we don't fill under the deck. It'll still be sealed but at least water can drain if any ever gets in.
