ABSTRACT:
Platform and ladder combinations for the transom of a boat have a platform unit and a step unit that may be moved between a use position with a step thereof immersed in the water in which the boat floats and a storage position where the step is located above the platform out of the water, which step in the use position extends aft of the platform unit and permits a person to climb out of the water and onto the platform without the step making any appreciable movement during such climb. The platform unit has a pair of tubular members with an inboard portion, a U-shaped outboard portion, a central portion and planking attached to the central portion of each the tubular members holding them spaced apart. The step unit is a tubular member defined by a middle section, two parallel, spaced apart end sections and planking fixed to short legs of the end sections forming a step. The end sections of the step unit are hinged to the tubular members of the platform unit adjacent a corner of its U-shaped outboard portions and the unattached ends of such portions act to limit the descent of the step unit when it is lowered into the use position.
