Seamanship is usually described as a litany of skills and knowledge of boat handling, navigation, deck work, and systems maintenance. The combined crew should be able to cover all of it. Ideally the boat is in better shape at the end of the trip than the beginning.
Adapted from the foreword to the 4th edition, The Annapolis Book of Seamanship,
“The art of sailing, maneuvering, and preserving a ship or a boat in all positions and under all reasonable circumstances.” This classic definition of “seamanship” has guided the preparation of this book for 30 years through four editions. Much has changed in boats, sails, and electronics, but with the addition of these words, “and some unreasonable circumstances, too,” that definition is as valid and essential today as it was in 1983.
