So...I decided to remove the nub of wood that I initially left in the bow keel. I just didn't sit well with me after all I'm doing to remove all wood from this boat. I did the same as the lower. Several layers of csm, layer of 3610, spraycore, and another layer of 3610. It should be stronger than before. I am also going to leave that area open to make room for ballast underneath instead of on the bow seats.
