PT-337 was a PT-103-class motor torpedo boat that was sunk in action during the Pacific Theater of World War II in Hansa Bay, New Guinea, on 7 March 1944.

Three or four more shells dropped near the 337, then one hit the tank compartment, just below the port gun turret, going through the engine room.

While they were away, Ensign Robert Hyde and Quartermaster Second Class (QM2c) Allen Gregory set out to swim to shore.

Most of the men had thought the three had reached the Island, but Watson, who said he saw Bales walking on the beach, is the only one who claimed to have seen any of them ashore.

On the morning of 9 March, the remaining men in the raft saw an overturned Japanese collapsible boat, floating a few yards away.

Cutter waved his arms to signal the plane, and they dropped supplies of water, food, cigarettes and medicine.

The next morning a PBY Catalina, from U.S. Navy Patrol Squadron VP 34, picked up the five survivors and took them to Dreger Harbour.
