Well I've blown it I have found two more voids one right on the transom. These are full of epoxy but the areas of coarse grain are still there so it must go right through the veneer. Overall this side of the hull is fair still a couple of low spots but they are quite small. So I am going to use West System Micro balloons as a filler to final fair the hull.
I am disappointed but I made compromises early on mainly due to cost, time and inexperience that I am paying for now. Well I'll know next time. The one good point is I won't have so much varnishing to do though I wood still like to have a clear finish on the decks and interior.
I'll know for the next one I build.
Still no luck finding a trailer.
