ABSTRACT:
An automatically retractable step assembly for watercraft rotatably mounts to a fixed step assembly fixed to the craft, a movable sliding chassis mounted on tracks, or a manually retractable step. The automatically retractable step assembly can also rotatably mount to another automatically retractable step assembly. The automatically retractable step assembly is preferably formed by a U-shaped member with outward projections that rotatably fit over mating projections from a supporting element. The U-shaped member is biased by torsion springs to rotate with respect to the supporting elements towards a position in which the retractable step assembly will be stored and away from the water. The retractable step assembly, during use, is rotatable against the bias and towards or into the water by pulling or stepping on the retractable step.
