ships to be poor sea boats; they were bow-heavy when fully equipped and very "wet" as high as the bridge. This problem was mitigated to some extent by replacement of the straight stem with an "Atlantic bow" to both Gneisenau and Scharnhorst in January and August 1939 respectively; use of the "A" turret remained restricted in heavy seas. The ships' stern was also frequently "wet", they were very slow entering a turn, and always required assistance from tugboats in shallow waters. With the rudder hard over, the ships lost over 50% speed and heeled over more than 10°. During trials, the ships heeled as much as 13° at hard rudder.Scharnhorst and Gneisenau had a crew of between 56 and 60 officers and 1,613 to 1,780 enlisted men. The crew was augmented by another 10 officers and 61 men when serving as a squadron flagship. They carried a number of smaller watercraft, including two picket boats, two launches, two barges, two pinnaces, two cutters, two yawls, and two dinghies. Propulsion Initially, diesel propulsion was planned for these ships, as had been used for the three Panzerschiffe. It was decided to use superheated steam propulsion, as the required total output for the desired speed was three times that of the Panzerschiffe. In the case of triple-screw ships, this would have meant more than twice the horsepower per shaft of the Panzerschiffe, and in the case of a quadruple-screw ship, this would have amounted to more than 40,000 horsepower per shaft. This requirement was beyond the diesel technology then available, and devising engines that could meet this demand would take an unforeseeable amount of time. Since high-pressure superheated steam had already proved successful, it was considered the most suitable choice for high power machinery.Scharnhorst was powered by three Brown, Boveri, & Co geared steam turbines, while Gneisenau was equipped with three Germania geared turbines. The turbines drove three-bladed screws that were in diameter. Steam was provided to the turbines by 12 Wagner ultra-high-pressure oil-fired water-tube boilers, which produced pressures up to and temperatures up to . The engines were rated at at 265 revolutions per minute (rpm), and on trials produced up to at 280 rpm. When steaming in reverse, the engines were rated for . The ships had a designed speed of ; on trials both vessels beat their designed speeds—Scharnhorst hit and Gneisenau made . The ships carried of fuel oil
