If you're interested in learning more about solo sailing voyages, the new non-fiction book "Sailing Alone: A Surprising History of Isolation and Survival at Sea" by Richard King is fascinating.
Another recommendation: Racundra's First Cruise by Arthur Ransome.
Also, John Guzzwell circumnavigated his self built 20 footer named Trekka from 1955 to 1959 and wrote a great book about it.
