Sailors, indeed anyone interested in the development of sailing craft, will be for ever indebted to Joseph Needham. Today they will find with ease literature that describes the origins, characteristics, and development of sailing craft in the various regions of the world; the inter-relationships between natural products, and native hull stuctures and forms, sails' fabrics, shapes, and performance. They can learn, too, that the closestowing anchor, the water-tight bulkhead, the balanced rudder (and other features of the modern efficiency-conscious ship constructor) have all been adapted from the millenniaold, so-long-despised by Westerners, Chinese junk, just as has, late in this twentieth century, the stiffened sail of the modern high-performance yacht.
