<p>A platform unit (2) is seated on the tail (5) of a hull (1) of a boat and may be lowered by powered actuator means (8) down guides (7) on an incline (6) to descend into the water. This exposes steps (62) in the incline which function with steps (213) in the platform unit (2) to enable a swimmer to climb up out of the water onto the main boat deck.</p> |
