The exploits of the U.S. Navy's 'Patrol Torpedo' or PT Boat crews became famous during WWII. Known by the Japanese as "devil boats", the little PTs landed big blows on the enemy, sinking numerous ships and supply barges. They also laid mines, carried out intelligence operations, and performed search and rescue operations among other tasks. While the most famous boat of the war was PT-109, commanded by future President John F. Kennedy, PT-73 also gained fame as the star of the TV show McHale's Navy starring Ernest Borgnine. Originally created in 1945 by the Bureau of Ships, "Know Your PT Boat" was intended to educate the crews of motor torpedo boats about all aspects of PT operation and maintenance in the field. Filled with advice drawn from the battle-tested crews of the "mosquito fleet", and featuring hilarious (and sometimes impolite) cartoon illustrations, it's sometimes hard to believe this booklet was an official U.S. Navy publication. This softcover reprint features the original book in its entirety.
