A moonpool work table able to provide an opening to a moonpool including a first set of opposing table doors having opposing vertical faces and moveable between an open position and one or more closed positions, and a second set of opposing table doors moveable between an open position and one or more closed positions in a transverse direction to that of the first set of table doors. In this way, the first and second set of table doors are able to define a box that can more closely and tightly define the area or envelope through which a conduit or the like can pass.

A cover adapted to be reversibly attached over an opening of a storage compartment contained on a personal watercraft. The cover includes a generally planar substrate having formed therein a dry storage chamber and at least one additional feature selected from the group consisting of a cup holder, an equipment rail, a surround tray, an accessory mounting plate, and a magnetic surface.

Provided is a locking apparatus for a damping device of a moonpool, which can automatically lock and unlock an opened state of the damping device of the moonpool. The locking apparatus includes: one or more first locking members installed in a sidewall of the moonpool; one or more second locking members installed in a side of the damping device; and a holding unit separably holding the first locking members and the second locking members when the damping devices are in the opened state.

A simple shelter for flood evacuation that is lightweight and easy to carry, compact in storage, and low in cost includes a substantially cylindrical floating body formed by a plurality of floats stacked in a vertical direction, where vertically adjacent floats are connected to each other; and two partition plates provided on the inner peripheral side of the uppermost and lowermost floats, respectively, of the plurality of floats, the inner peripheral surface of the floating body and the two partition plates form a closed accommodation space for accommodating evacuees by preventing water from entering from the outside, and a door for evacuees to enter and exit the accommodation space is provided in the two partition plates.

A water-tight or air-tight accessible compartment has a removable hatch sealed at the edge with elastically conformable opposing seals, with elongate communication elements extending into the compartment between the opposing seals, seals conforming to the topology formed between the compartment edge and the elongate communication elements.

The present utility model patent application discloses a hermetic hatch applied to boats, capable of opening in two directions according to its installed position on the vessel, providing practicality, safety, and ease of handling. The innovation aims to ensure safety and ergonomics for accessing vessel compartments, both from inside and outside. The hatch provides highly effective hermetic sealing against fluids, while allowing practical bidirectional opening: left-to-right and right-to-left, without compromising the hermetic seal. Field of application: boats, nautical engineering, and safety.
