Abstract
A boarding step is disclosed for mounting on a towing ring (9) fixedly disposed on the stem (19) of a pleasure craft, for facilitating the stepping into and out of the craft. The boarding step comprises two carrier arms (1) which at their portions (4) which are urged against the craft and have rubber coatings, and which, at their outer ends, are provided with a horizontal tread platform (2). The tread platform has, on its underface, an adjustment rail (5) with a number of alternative pivotal anchorage points (14) for a support strut (6) which, at its end facing the craft, is provided with a pivotal, U-shaped abutment portion (7) urged against the stem (19) of the craft. The support strut has a number of alternative anchorage points (11) for a bolt (10) which also engages with the ring (9) fixed in the stem and which, on tightening, urges the boarding step to a positionally-fixing frictional engagement with the craft. An adjustable stay (15) extends between the carrier arms and the support strut.
