Mike, I don't know if this will help out or not, but I like the stuff.....polyurethane glue is waterproof, sandable, paintable and has the additional property of expanding to fill imperfections. Because it expands, however, it will leave small bubble dimples in the exposed service of the glue, which may be filled with anything from putty to paint. I mention this solely to keep you from expecting a "too slick" surface on the glue itself. I honestly think if you give it a shot on a sample project, you will be impressed. It runs into the smallest of imperfections, so that must be kept in mind when applying. It's not perfect for every job, but it is ideal for many.

How much of the length of the boat have you decided to remove? I ask because I'm concerned about the bow rise. I would think it possibly disastrous to catch the point of the bow on a rock, due to the weight distribution being too far forward. (Probably something you have already taken into consideration.)

Good Fun to You!
