Bobby - here's the layup that I used for the Bracket Tub.
2 layers of 1/2 oz mat
2 layers of 1708
8 layers of alternating 1/2 oz mat and 18 oz roving
All corners were done with 6" wide overlapping 1708 tape.
The bottom/side pieces overlap at the "keel" to there are essentially 16 layers over an inch of glass at the keel.
The tub took about 6 gallons of resin.
The swim platform part took about 2.5 gallons
I'm gonna core the platform, so I'll probably use up another 2 gallons of resin.
The widest part of the bracket was 38" (b/c I had 38" wide 1/2oz mat).
The engine stand would have helped a lot during the layup.
