Since my hull came out a little thin, I decided on a little more reinforcement than on my last build. I made a piece that was part "football" and part end strip. I have noticed that scratches from grounding happen most often directly under the waterline. The reinforcing strips that go all the way up the stem & stern don't really do anything.
I also took Jay Babina's advice, and put the small piece under the big one. This absolutely works better- no strings or fuzz, it all blends right together.
The glassing seemed to go well, but I had forgotten how much epoxy a double layer will drink up.
The glass did ripple under the double layer. I don't know if it was just because it was double, or because the small piece is underneath. I haven't had this happen since my first build. At least I know what to do about it-grind, scrape, coat, etc.
