Power Squadron Sailing courses and DC book
The Dennis Connor book, "Learn to Sail" is very good. The texts for the two part US Power Squadron (USPS)Sailing Course, as well as, the course itself are excellent. If you are a beginner, it is not unusual to have an on the water sailboat ride included in the instruction as part of the Power Squadron course (the cost of the course for members is only the texts and materials). For follow up and to expand your knowledge, USPS courses such as "Seamanship" and "Piloting" are also excellent. They are especially valuable for learning those things that you need to know, but that are hard to learn on your own; like how to read a chart and a compass, traditions, rules of the road, etiquette, marlinspike seamanship, etc.
