A total of 112 coastal tankers, known as Y boats, were built for the U.S. Army by 8 small shipbuilders, notably Odenbach Shipbuilding, in Rochester NY. All were of steel and were either 162 or 182 feet in length. After the war many were transferred to overseas owners and many became bunkering barges, both in the U.S. and overseas, but large numbers are unaccounted for. If anyone knows of the whereabouts or final fate of a Y boat that's not already reported below, please e-mail me at tim@coltoncompany.com
