U-Boat Crew. The crew numbers aboard a U-boat varied greatly between different U-boat types and the mission it was undertaking. A Type II U-boat comprised of 25 officers and seamen, while a Type VII housed approximately 45. A Type IX had about 50 and Type XXI had a 57 man crew. Sometimes U-boats carried specialist crews on special missions, such as scientists, spies or commandos.
The role of a coxswain in a crew is to: 1  Keep the boat and rowers safe at all times by properly steering the boat (according to the river or regatta rules and safety for the crew). 2  Be in command of the boat at all times. 3  Coach the crew when the coach is not present. 4  Provide motivation and encouragement to the crew.
