The live well lid system may comprise a lid, a hinge, a motor, a lift arm, a lid track, and a local foot control. The live well lid system may be a system for covering and uncovering a live well of a boat by pivoting the lid of the live well responsive to input from the local foot control. The live well lid system may be adapted for a user to pivot the lid by operating the local foot control located proximate to the live well without diverting the attention of the user or requiring use of the user's hands. In some embodiments, a remote foot control may be a secondary control located at a remote location on the boat.

An apparatus is disclosed for opening and closing a grain or access door on a barge lid or cover, the grain door having a latch connecting the grain door to the barge lid, the apparatus supportable by an overhead lifting system. The apparatus can include a base which is supportable by the overhead lifting system and a mechanical arm assembly connected to the base, the mechanical arm assembly including a first arm rotatably connected to the base, a second arm connected to the first arm, a latch engagement member connected to the second arm; and an actuator connected between the first arm and the second arm, the actuator operable to move the second arm relative to the first arm to disengage the latch on the grain door from the barge lid via the latch engagement member and swing the grain door from a closed position to an open position.

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 lift assist mechanism is provided for positioning a hatch cover in relation to a corresponding opening in a hatch frame. The assist mechanism includes a torsion bar and a lifting mechanism. The torsion bar has first and second opposite ends. The first end secures to the hatch frame. The second end connects to a bar spur gear. The lifting assembly includes a lift spur gear and a hinge gear. The lift spur gear engages the bar spur gear. The gears convert an acute angle twist of the bar to substantially perpendicular pivot the hatch cover from the hatch frame.

A boat includes a hull provided with a rear stern hatch located in correspondence with an internal stern compartment of the hull and suitable for opening and closing in correspondence with an aperture of the compartment, the hatch having a body with opposed side located in correspondence with side walls of the compartment and a upper edge and a lower edge. The hatch includes an actuator to open and close the compartment arranged inside its own body. The actuator rotatably constraining at least one of the sides of the hatch to the hull. The body being not provided with any further connections of the sides to the hull.
