Tips from Mr. Mancebo:
I like the ease of using fiberglass. But I have also heard horror stories of people becoming sensitized. Before working with epoxy, download the System three's book http://www.systemthree.com/reslibrary/literature/The_Epoxy_Book.pdf and actually read it.
1. Use Nitrile gloves and wear a double pair. Keep gloves that aren't trashed in bucket and use them as the outer pair.
2. I have a garage attached to the house and did not want to fumigate the rest of the family. Mr. Mancebo recommended System Three General Purpose Epoxy. Most nights I do wear a respirator, but on nights that I don't, the order is barely detectable.
3. Use chip brushes to apply epoxy and work the fiberglass tape. Cut the top third off the brush. I tried it both ways and cutting the tip significantly improved spreading the epoxy.

Mancebo's Design
The neat thing about the PDR sail boats is they are relatively simple to build. Mr. Mancebo's design uses 1/4" plywood and the stitch and glue ( http://en.wikipedia.org/wiki/Stitch_and_glue ) method. The sides are buoyancy tanks making the boat unsinkable. The four side panels are exactly the same which allowed me to make one pattern and then trace the succeeding panels. The mast, rudder, and centerboard are all made from cedar. I'll hit Mr. Mancebo up for a write up on his design, once he makes them available.
