High Quality Content by WIKIPEDIA articles! Generally Schnellboot or S-boot ("fast boat"), is the designation for Motor Torpedo Boats of the German Navy since 1932. In particular it applies to that type of Boat that saw service during World War II. The Schnellboot was then called an E-boat by the Allies; it is commonly held that the "E" stood for "Enemy", but it is possible that it stood for "Eilboot" ("hurry boat"). The S-boot was much larger than the American PT boat and the British Motor Torpedo Boat (MTB). The S-boot was better suited to the open sea and had substantially longer range (approximately 700 nautical miles), which resulted in the Royal Navy developing many later versions of MTBs, using the Fairmile 'D' hull design.
