The powered retractable ship ladder replaces the current technology of manually-lowered ship ladders. The powered ladder includes powered extension and retraction, with the added capability of being able to lift a user during ladder retraction. The ladder is formed from a collection of links. The links only permit the ladder to bend in one direction, thus keeping the extended ladder against the side of the ship, rather than swinging toward and away from the ship.
