During World War II, the U.S. Navy swiftly expanded to include an array of vessels, from smaller yachts and fishing boats bought early in the war for patrol work to fast, modern commercial ships built to haul troops and supplies. After the Allied victory, this diverse fleet became unnecessary and the Navy sold many of its vessels. This comprehensive catalog documents the Navy ships and boats sold after the war and registered under the American flag for commercial or recreational purposes. Focusing on those vessels with names or clearly identifiable hull numbers and crew accommodations, it chronicles each craft’s prewar ownership, wartime history, and postwar fate. The product of painstaking detective work in a wide-range of primary sources, this meticulous directory highlights an unexplored but illuminating aspect of U.S. maritime history.
