The Art and Science of Sails
by Whidden, Tom & Michael Levitt
2nd ed. A guide to modern sail technology from the top brass at North Sails. Whidden, who has been Dennis Conner’s tactician in several America’s Cup campaigns, has completely revised the previous edition to cover new cloths, new technology, and new practices. The book explains the theories behind making a boat move, how sails and their structure and composition can affect boat speed, and many other factors that make a boat go fast…or not.
