ABSTRACT:
A ladder device for a boat has a mount unit and a separate 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 out of the water. The step in the use position extends aft of the platform and permits a person to climb out of the water and onto the platform without the step making any appreciable movement relative to the boat during such climb. The mount unit has a pair of U-shaped members formed of a section of tubing with first and second ends and a transverse flange is fixed to each first end by which the members may be attached to the upper surface of the platform. The step unit has two parallel S-shaped tubular side sections, each including a long central portion from which upper and lower end portions extend integrally and substantially normally. A step is fixed at its ends to the lower end portions holding the side sections spaced apart from each other. The step unit is pinned to the mount unit for movement of the step unit between the use position and the storage position. Several multistep embodiments are disclosed.
