Zusammenfassung:	A watercraft may include a crane for lifting loads. The crane may include a tower and a boom that is rotatble with respect to the tower. The tower may be positioned inside the outer contour of the watercraft so as to minimize the profile of the watercraft on radar. The watercraft may include a superstructure within which the tower may be disposed. The superstructure may include planar outer walls that are obtuse relative to a horizontal plane. A rotary bearing may be utilized to connect the boom to the tower and permit the boom to rotate relative to the tower. Further, when the boom is in a rest position, a lower edge of the boom may be positioned 10 cm or less above the crane deck.
