A Marine Structure for use in a body of water, having a deck positioned above the water's surface, and a vessel landing stage position at the water surface. A stairway having its upper and hinged to the deck, is normally supported with its lower end in contact with the landing stage. An elevating mechanism depending from the deck is operable to lift the stairway's lower end to a position above the water's surface, adjacent to the deck. The stairway is retained in its raised position by a docking facility, and is secured thereby from damage which could otherwise occur due to strong wind and wave action. An alignment coupling carried on the respective stairway and docking facility allows the two members to be firmly, yet resiliently joined to better resist wind or wave forces.
