The transom and bow deck section undersides were fiberglassed with 1.5 oz chopped strand mat. The middle ply had some problems that needed to be fixed first.
The bottom sides are waterproofed very well.
I got together a few scraps of 1708 biaxial fiberglass and glassed in the tip of the stringer to the right (starboard). I am totally out of 1708 at this point!
The weather has been great so far. Maybe a little too good. Because of the heat and dehydration I've had to start taking a day off after working on the Batboat to recover. Now I know why all those guys at the iboats forums drink a lot of beer! lol!
