This edition of The Annapolis Book of Seamanship is an extensive update. Much of the text is new or revised, and there are many new photos. Throughout, the book stresses the skills and attitudes that comprise what the author calls “The Seamanship Ethos.” The first four chapters cover the boat, basic sailing skills, sail trim, and weather, with the first of many “Hands On” sections with their tips. The topics of health (including seasickness) and on board safety follow, with lessons learned from on-water tests and studies of boating accidents. We look closely at the elements of piloting, navigation, and electronics, including Digital Selective Calling, the US Coast Guard’s emergency communication system. Moving on to the arts of traditional seamanship—anchoring, heavy weather, and emergencies—there is much on modern equipment and skills, again based on experience. The book ends with boat maintenance and the traditions that make sailing the beloved pastime it is. Appendixes include best practices for protecting the marine environment and bringing up children under sail.
