The book provides a fascinating insight into the history of sailing explored through a hundred objects that have been pivotal in the development of sailing and saling boats. From the earliest water-borne craft, through magnificent Viking warships, to the technology that powers some of the most sophisticated modern yachts, the book also covers key developments such as keeps, and navigational aids, including the astrolabe, sextant, and compass. Other more apparently esoteric objects from all around the world are also explored, including the importance of citrus fruit in the prevention of scurvy, scrimshaw made from whalebone, and the meaning of sailor's tattoos.
