I never knew either until I was motivated to check it out after your post.Hand built wood boats of any type are cool. I built a wooden stitch and glue kayak. There is a gentleman that lives near me and told the story of building a 44' catamaran by himself. He said he sailed away with 2500 bucks. After 5 years of sailing around the world, living on remote islands and other unique locations, he returned home. I thought the story seemed a little far fetched, but he has an album of newspaper articles, photos and other documents from around the world as proof. Neat story.
