A system for collection of rainwater in the open ocean may include: (a) one or more ocean-going vessels, wherein each ocean-going vessel is configured for collection and storage of rainwater, wherein each ocean-going vessel is configured to drift with surface ocean currents in order to navigate to one or more delivery locations, wherein each delivery location is on or near to a land mass; and (b) one or more delivery stations located at the one or more delivery locations, wherein each delivery station is configured to receive stored rainwater from one or more of the ocean-going vessels.

A ship is configured to obtain propelling force by driving a designed propeller with a main engine. A vertical tunnel is formed at a bow portion to pass through a ship bottom. A lateral tunnel is formed in communication with the vertical tunnel. An additional propeller device has an additional propeller and a driving unit for the propeller. The additional propeller device is configured such that the additional propeller can turn around a vertical center line of the vertical tunnel. The additional propeller is configured to be capable of vertically movable from below the ship bottom to a height position of the lateral tunnel. When the additional propeller is at the height position of the lateral tunnel, the additional propeller is configured to follow the lateral tunnel.

A watercraft and method of assembling thereof. The watercraft including a hull and a deck supported by the hull. The deck has an upper surface with support members connected to the deck. An interchangeable module rests on the upper surface of the deck. The interchangeable module has at least one of a seat and a storage compartment. The watercraft includes a mating member disposed on the interchangeable module and removably engages the support member.

The present disclosure relates to a ship, and in a ship including a cargo area for storing cargo, a forecastle area provided fore of the cargo area, and an aft area provided aft of the cargo area, the forecastle area includes a fore deck dividing an interior and an exterior of a hull, and a cabin is provided on an upper part of the fore deck, wherein the cabin has a flat cross-section with a width that decreases forward toward a bow.

A personal watercraft is provided that comprises a hull, a deck, a saddle seat, and a handlebar. The deck is provided to an upper portion of the hull. The saddle seat is supported by the deck and positioned in a center of the personal watercraft. The handlebar is disposed in the center of the personal watercraft and above the deck in front of the saddle seat. The deck includes a first lateral storage recess and a first storage hatch configured to be opened to expose the first lateral storage recess and closed to cover the first lateral storage recess. The first lateral storage recess has a front end disposed in front of a rear edge of the saddle seat and a rear end disposed adjacent a rear end of the hull. The first storage hatch has a planar surface forming a portion of an upper surface of the deck.
