Re: Ketch racing - Any good books?
Looked at my pile of books Sail Power is by Wallace Ross. Doesn't have much, few pages on mizzen staysails. Still a good sail trim book. Understanding Rigs and Rigging Richard Henderson has a little also. I sail a cutter and had sloops never a ketch or yawl so you may find other books. Try a search on Google it will probably be a older no longer in print type of book.
