''PT-796'' is a 78-foot PT boat built by Higgins Industries of New Orleans in 1945. It was designated a National Historic Landmark in 1986 as one of a very few surviving PT boats, which were built in large numbers during World War II. She is part of the collection of the PT Boat Museum, which itself is part of the Battleship Cove museum in Fall River, Massachusetts.〔 ==Design== ''PT-796'' was laid down on 3 May 1945, launched on 23 June, and completed after the end of the war on 26 October. The last of her type to be constructed, she was nicknamed ''Tail Ender''. The hull was constructed of two layers of planking. Unlike earlier PT boats, where the layers were laid diagonally, the outer layer of ''PT-796''s hull is laid longitudinally, a change to the design believed to have been made to Higgins boats sometime in late 1944. Also, instead of two layers of mahogany, the inner layer is spruce. The two layers are held together by copper rivets and bronze screws, with a sheet of canvas impregnated with marine glue between them. The boat's full-load displacement is . She is in length, with a beam of , and a draft of . Her three 12-cylinder Packard V-12 engines each drove a single shaft, giving the boat a top speed of .

She was also fitted with two Mark 50 rocket launchers, and a smoke generator at the stern.〔(【引用サイトリンク】title=PT-796 )〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Motor Torpedo Boat PT 796」の詳細全文を読む スポンサード リンク
