Your in luck....
If you check the guest forum, the gentleman who wrote the Sail Trim Charts is moderating that forum.If you don't have the sail trim charts, get them (look in the chandlery), they are a great investment.There is a new book with more info on using the sail charts that I have on order and can't wait to get my hands on to read.Look in the store, both are available and if the book increases my ability to set and read the sails half as much as the charts, it's a great deal.Regards.BruceNeon Moon
