Abstract
The invention relates to a foldout stern-lowering means (1) which constitutes an integral part of the watercraft (38) and has at least three sectors (A, B, C) which can be walked on and optionally three further sectors (D, E, F) which can be walked on, with three different foldout modes: gangway, stairs and tender, with a safety means on the lifting means (18) in order always to return the stern-lowering means (1) into the starting position, and a safety means by means of an emergency lifting means (31) for people, and also to compensate for the additional weight of a stern-lowering means (1) by means of buoyancy means (39, 39a) and to increase the comfort while underway and before anchoring, assisted by slosh plates (40).
