Subtitled "a primer of sailing" it really is an excellent guide to understand how wind and water affect boats. Aside from basic seamanship, Jan also includes drawings of the primary types of sailboats, so you'll see what makes a schooner a schooner, a cutter a cutter, etc. Jan uses Ants and Peanuts to help clarify vectors. How can you miss out on Ants and Peanuts! It's a favorite how-to-sail by young and the not-so-young folks learning to sail.
