SAILS AND THE WAY THEY WORK

In this gem of a book, Harvey describes the origins of the different shapes of sail, the way they work, and the practical differences between the various rigs in their handling and perfomance out on the water. Next the explains the principles of sail design, advises on choice of sailcloth, and shows how a basic home computer can be used to plot the panel shapes so that DYA sailmakers can save as much as three-quarters of the cost of small boat sails by making them or recutting old ones.
