One of the best examples of a surviving Higgins boat is "PT-658", one of two 100% authentically restored and operational U.S. Navy PT boats afloat today. Relaunched after hull restoration from 1995 to 2005, it is located at Pier 308, Vigor Shipyard in Portland, Oregon's Swan Island Lagoon. Maintained by an all volunteer group, it is powered by the three Packard V12 5M-2500 gas engines and includes all weapons, electronics, equipment and accessories restored to appear as they did the day the US Navy accepted the boat, 31 July 1945.
