A ladder system through which a ladder is retained on a deck of a watercraft by a track arrangement and positioned at a first location in an opening for an enclosure where the ladder is substantially vertical to the side of the watercraft to permit ingress/egress of a person between a body of water and the deck. The ladder is connected to a rail of the track arrangement by a first and second hinges that permits the ladder to be rotated from the vertical position along the side of the watercraft to a position inside of the enclosure. The ladder may thereafter be moved from the opening to a location adjacent the gate and behind the enclosure to conceal and stow the ladder such that the exterior surface of the watercraft along the enclosure is substantially uniform from stem to stern.
