You will start with just one book but when you have finished it you will want another. Sail power by Wallace Ross will teach you more than you can absorb about sail trim. It is not a learn to sail book. Likely the books
as used by the sailing schools and clubs would be good. I do not have a copy, the students bring their own and the teaching commmander lets us know what is on the agenda. The Nature of Boats by David Gerr is an excellent all round book about boats but again it is not a learn to sail book.
If you were in my area and keen I would take you out on my boat
. You may find someone like that in your area. But you must be keen. You can not learn it all in a few lessons. If I had a new keen crew that sailed every week throughout the year, I would say that they would learn a lot by the end of the year. From there I would say buy a boat
and good luck.
