Apparatus for a door for a boat's companionway hatch. The door includes a frame, a door, a drive mechanism, and a receiver. The drive mechanism moves the door between an open and closed position to selectively allow and block access to a bulkhead opening in the companionway. In the open position, the edge of the door is substantially parallel with the companionway sidewall. In the closed position the edge of the door engages the receiver and the edge is substantially parallel with the sidewall to which the receiver is attached. The drive mechanism includes a pair of struts that are driven by an actuator to move with a scissors-like motion. One end of each strut is fixed in position. The opposite end of each strut has a roller that moves within a slot, with one slot in the door and the other slot in the frame.

A retractable boat center console enclosure device is disclosed that can be installed on an open center console of a boat. The retractable boat center console enclosure device comprises a body component that is configured in a plurality of sections which act to cover the center console of the boat. A double wall component is positioned in the port and starboard sides with a motorized track so that the body component could rise up over the gunnels of the sides to contour to the boat. The retractable sides then meet in the center of the hull approximately six feet in height to snap together.

Provided is a door which has a first sash, at least a second sash slidable along rails, and at least one automatic fastening device for automatically fastening the at least one second sash to the first sash when the at least one second sash reaches an engagement position with an abutment part of the first sash. A control system moves the rails relative to frame cross-pieces between a forward position in which the rails are engageable with the at least one second sash, and a retracted position in which the rails are non-interfering with the at least one second sash, allowing a sash pack formed by the first sash and the at least one second sash fastened to the first sash to rotate about a vertical axis.

A sliding cover assembly for a vehicle, in particular a waterborne vehicle, the sliding cover assembly having a cover element displaceable between a closed position, in which a roof opening is closed, and an open position, in which the roof opening is at least partially open, and a displacement mechanism for the cover element, the displacement mechanism having a slider on either side of a longitudinal center plane of the cover element, each slider being guided in a sliding manner in a respective guide rail attached to the roof, and a raising lever connected to the cover element being hinged to each slider. The sliders each have a slider body and a control element which is mounted on the slider body in such a manner that it can rotate about an axis of rotation and to which the respective raising lever is hinged eccentrically relative to the axis of rotation.

A marine vessel has a hull with a bow, a stern, starboard and port sides, a deck on the hull, and a console located on the deck between the starboard side and the port side and between the bow and the stern. The console has a helm for the marine vessel and a console windshield which shields the helm from wind. A cover extends over the helm. An auxiliary windshield is coupled to the cover, the auxiliary windshield being movable into and between a stowed position in which the auxiliary windshield is stowed in the cover and a deployed position in which the auxiliary windshield extends downwardly from the cover into a gap between the console and one of the starboard side and the port side.

A material-actuated door includes a door housing including a flexible material; and one or more least one Shape Memory Alloy (SMA) actuators embedded in the door housing. Each SMA actuator is elastically biased in a first actuator physical state and is configured to transition into a second actuator physical state in response to receiving electrical current. The material-actuated door is transitioned into a first door position in response to disconnecting the electrical current to the at least one SMA actuator, and is transitioned into a second door position in response to delivering the electrical current to the at least one SMA actuator.
