The present invention relates to a rotating and sliding boat boarding door mechanism configured to aid the vessel's occupants in their ingress and egress to and from the vessel. More particularly, the present invention provides a rotating and sliding boat boarding door assembly and system that slidingly moves into a recess in the vessel's exterior (e.g., side, transom, and/or gunwale) that has been configured to receive and maintain the boarding door assembly in a position where it is out of sight when fully recessed.

A passenger vessel 10 configured to moor along an improved or unimproved shoreline to load or unload the vessel via the bow includes a hull 20 having a movable, openable bow member 24 configured to be moved between a closed state and an open state which exposes the hull's interior volume and an extendable and steerable ramp assembly 14 including an elongated extendable ramp member 78 configured to be stowed in the hull's interior when the bow member is in the closed state. The ramp member is extendable by being conveyed forwardly through the bow opening to define a distally projecting ramp extension supported and steerable (vertically and laterally) from a pivot or swing mount frame 84 affixed within the hull 20.

An escape apparatus for a vessel includes a support frame that is configured to be installed at the vessel and that defines defining an exit opening, an escape door located at an inner side of the exit opening and configured to open and close the exit opening, where the escape door defines an accommodation space, a floater located in the accommodation space of the escape door and configured to be raised relative to the support frame, and an unlocking device configured to, based on being pushed by the raised floater, release coupling between the escape door and the support frame.

A closing device configured to close an outer shell opening of a surface ship, including several substantially vertically mounted shutter lamellas and a drive device by means of which the shutter lamellas can be actuated such that they move between a closed position and an open position.
