Boatspeed really does make you a tactical genius. Lawrie Smith and Andrew Preece are two of the fastest sailors in the business, what makes them so fast? We asked them, and their answers form the text of this book. They identify the key elements of boat speed, explain the theory of each - so you understand what you're trying to do - then show you how to use your new knowledge to sail blisteringly fast. You'll find, like them, that it's more fun at the front of the fleet.
