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 moveable component assembly includes a seat assembly, a track system, and a locking mechanism that secures the seat assembly in position. The track system is coupled at least indirectly to the seat assembly and guides the seat assembly along a path between a first and second position. The seat assembly is secured in the second position when the seat assembly is disposed away from the deck's walking surface, thereby resulting in the components of the track system being frictionally coupled. A floor panel includes a locking mechanism and a series of alignment surfaces that guide the floor panel into position, which is secured by the locking mechanism.

The present disclosure provides an inexpensive rain-guard device for shipping, that can cope with large vessels. The rain-guard device for shipping has a rail 19, which is disposed on a sliding hatch cover 11, an on-board chute 22, which is provided on the rail 19 in a travelable manner, covers part of a hatch opening 13, and, furthermore, supplies cargo from a shiploader 1 into a hold 7, and a lid member 23, which covers another part of the hatch opening 13, and the lid member 23 is disposed both in front and in rear in the traveling direction of the on-board chute 22, and, furthermore, configured to expand and contract as the on-board chute 22 travels.

A sliding roof panel assembly for covering a roof opening of a marine craft is disclosed. The sliding roof panel assembly comprises a slide guide for attachment along one side of the roof opening, a roof panel which is slidably moveable between an open and lifted position and a closed and lowered position, the roof opening being covered by the roof panel in the closed and lowered position, and a slide assembly guided for travel along the slide guide and supporting the roof panel. The slide guide has a slide track and a guide rail, the slide track and the guide rail each extending along the slide guide, the guide rail having a forward depressed portion and a rearward raised portion. The slide assembly comprises a drive slide driveably moveable along the slide track of the slide guide, a guide rail follower supported by and moveable along the guide rail, the guide rail follower supporting the roof panel, and a first lever, linking the drive slide and the roof panel via respective rotatable links. In use, the roof panel is slidably moveable from the open and lifted position to the closed and lowered position by driving the drive slide forward in the slide track to move the guide rail follower forward along the rearward raised portion of the guide rail until the guide rail follower reaches the forward depressed portion of the guide rail. The guide rail follower travels downwardly along the forward depressed portion of the guide rail relative to the drive slide by the weight of the roof panel and rotation of the first lever, the roof panel following the movement of the guide rail follower downwardly towards the closed and lowered position.

A slide system includes a component assembly, a track system, a floor panel, and a below-deck cavity. The track system is coupled at least indirectly to the component assembly for guiding movement of the component assembly along a path. The floor panel includes an upper surface. The below-deck cavity is disposed below the floor panel. The component assembly is located substantially above the floor panel. The track system is located within the below deck cavity and below the upper surface.
