The body part 10, 11 has a ladder portion 2 and a supporting portion 3, by means of which the ladder portion 2 in its bow ladder position may be supported against the stem of the boat, said ladder portion 2 and supporting portion 3 being coupled together by means of joints 19 by means of which the ladder portion 2 and the supporting portion 3 may be swung approximately 180 degrees relative to each other, such that they rest onto each other in line relative to each other, as continuations of each other. The supporting and gangway part 3 comprises a first walking plane 21, to which a second walking plane 20 can be swung or displaced to the walking plane 20 of the ladder portion 2 as a continuation of the supporting and gangway part 3. <IMAGE>
