ABSTRACT:
A retractable ladder assembly for a watercraft has a rotatably mounted ladder which is attached to the craft by brackets. The ladder is pivotably mounted to the brackets. There is a plate biased to engage and rotatably retract the ladder from a use position to a storage position is also attached to the bracket. The bias is provided by a torsion spring. In one embodiment, the bracket mounts to the top of a rear platform of a boat and in another embodiment the ladder mounts to the underside of the rear platform of the boat. In both embodiments, the ladder may have a telescoping second ladder which retracts, due to gravity, when the torsion spring rotates the ladder assembly to a sufficient amount above the horizontal. There is also a stopper mechanism for each embodiment.
