In general, one aspect disclosed features an in-davit run kit for a lifeboat, the kit comprising: a water container comprising a first connector; a hose configured to connect with the first connector; and a second connector configured to connect to the hose, wherein the second connector is in fluid communication with a water cooling system of the lifeboat; wherein the in-davit run kit allows a water pump of the lifeboat to draw water from the water container into the water cooling system of the lifeboat.

The patent discloses a multihull watercraft with a unique hull configuration providing numerous benefits. Passenger cabins are enclosed within a separate upper hull, which allows the accommodation space and the float hulls to be independently optimized. The new configuration also provides reduced windage, and creates additional deck space for easier boarding, recreational use, and safer access to shore craft.

A nautical vessel docking and storage system attaches to a nautical structure. A system includes a cradle having support elements that include lower portions, proximate and distal side portions, and proximate and distal side abutments; a vessel securing element; a hinge for each proximate side portion; and a puller for transitioning the cradle between docking and storage positions.

A retractable davit assembly includes a davit arm that retracts into a davit arm channel formed within the internal volume of a deck of the superstructure of a yacht or other vessel. An outer end of the davit arm includes a fairing matching a profile of the surrounding outer edge of the deck, such that that davit arm is concealed when retracted.

A portable gantry crane formed of composite members includes a composite material I-beam. Two or more support members are formed of a composite material and each support member supports the I-beam when the portable gantry crane is in an upright position. Two or more end housings are included, each end housing enclosing a top end of one of the two or more support members and coupled thereto using adhesive. A plurality of latch structures are coupled with the I-beam, each latch structure including a latch, and each end housing having a latch receiver, each latch in combination with a latch receiver allowing one of the latch structures to be releasably fixedly coupled with an end housing. In implementations a plurality of latch structures are coupled with the I-beam, each latch structure having a latch structure enclosure and each latch structure enclosure at least partially enclosing one of the end housings.

A lifeboat launch control system. The lifeboat launch control system has a wheel trunk that runs along the side of a ship. An axle box is vertically movable in the wheel trunk. The axle box has a pair of wheels on opposing sides of a bar. A shaft is removably inserted into the bar. The shaft is removable from the bar by a handle. When the shaft is removed from the bar, the lifeboat is released from the ship.
