Kevin O'Neill has a very nice wiki, called Wikiproa, wherein he has a group of proa enthusiasts and builders publishing the fruits of their building labors and commenting on the results (and the process). It's fun. There are accounts of the building processes and performance of the boats as well. Very relaxed and conversational. Many to Gary Dierking designs, and some indigenous archaic reference material. Highly recommended. For home build proa lovers, a feast.
