This book was mentioned by a few people (abbarr and kernix I recall) and was a great read.

The Strange Last Voyage of Donald Crowhurst.

If you can't find the paperback, there's an excellent documentary currently (10/25/12) available on Netflix called Deep Water (2006) that parallels the book amazingly well. It's loaded with archive video footage, interviews, and pictures. The book has a lot more of Crowhurst's writing, but Deep Water is definitely very well done.

It ends with footage of Crowhurst's trimaran Teignmouth Electron sitting in ruins on Cayman Brac. Even if you've read the book, I'd still recommend watching the documentary.
