That book you returned to the library was "The Complete Manual of Catamaran Racing," by Rick White, and it was the first book that explained how to rig, sail and race catamarans (published in 1976). Reg White, no relation, published an earlier book, but it was mostly devoted to the history of catamaran sailing/racing rather than the how-to's.

Jack Sammons wrote a book that came out in 1977, and following that were books by Jake Grubb and Phil Berman.

All of these are still valuable reference books -- and they help to track the history and development of the sport.
