Boats can include a swim platform with an integrated system of steps that can be selectively deployed and retracted. Such platforms can be attached to a transom of a boat or can be fabricated as an extended portion of the boat's hull. In another embodiment, deployable steps can be integrated with a boat's hull as a side-entry door. In order to reconfigure the step system into a deployed configuration, a linkage is actuated that causes the step system to unfold, forming steps (or a seating configuration) at least partially below the water line. Since the steps can be deployed below the water line, a swimmer can more easily get on board the boat.

A sustainable floating community based on a mass-produced modular, pre-fabricated kit of parts referred to as floating modular units. The floating modular units are designed to allow for various needs while remaining simple to deliver and assemble by hand in remote destinations prone to volatile shifts in water levels and currents. The floating modular units are ready to assemble, can be erected for use on land and bodies of water, are easily collapsible for transport, thereby serving as highly adaptable transportable structures.

A jet boat basically includes a hull, a first jet propulsion unit, a second jet propulsion unit, and a steering unit. The first jet propulsion unit is provided to the hull. The first jet propulsion unit has a first steering deflector with a first propulsion axis. The first steering deflector is movable with respect to the hull. The second jet propulsion unit is provided to the hull. The second jet propulsion unit has a second steering deflector with a second propulsion axis. The second steering deflector is movable with respect to the hull. The steering unit is operatively coupled to the first and second jet propulsion units. The first and second steering deflectors are oriented such that the first and second propulsion axes are non-parallel to a longitudinal center axis of the hull while the steering unit is in a straight steering position.

A system for controlling passenger services includes a sensor that generates a signal representative of the at least one of the position of the seat, the presence of passenger in the seat, the position of the at least one hand of the passenger, the configuration of the at least one hand of the passenger and the direction of movement of the at least one hand of the passenger. A first light source, an air supply, and a window shade are disposed at a predetermined locations with respect to the seat. A controller, connected to the sensor, generates a control signal that controls at least one parameter associated with at least one of light generated by the first light source, air supplied by the air supply and a degree of openness of the window shade.

The invention encompasses fire-escape models of off-shore rigs with emphasis on a Detachable Island Rig (DIR) instantly unlocked upon a rig-fire, from a permanent under-water basement, saving property and personnel. The devised water-seal of its basement's in-situ fire-escape entry, not destroyed upon a rig-fire, serves as an exceptional model (named Sumathi Paturu in-situ Model, after its inventor) for an in-site fire-escape with a similar water-seal for jack-up rigs without a basement. An off-site modular is an unlimited air-source for all fire-escape units. A spray-room with converging spray-walks, or spray-tracks with track-drives or a simpler means of spray-drives are safe evacuation accessories workable even with minimal expendable cost and space. In the foregoing, vital needs like safe evacuation, food, and fresh air are devised as affirmed provisions, whereas the wheeled life-boats and lift-boats are let out boarded or un-boarded, upon a click of a remote control, with no collision injury.

An outboard motor boat is provided with a hull, a deck, at least one outboard motor and a bulwark. The hull includes a rear portion. The deck is provided on the hull. The at least one outboard motor is mounted to the rear portion of the hull. The bulwark is provided on the deck. The deck includes an aft deck in the rear of the deck. The aft deck includes a first part disposed forward of the outboard motor and a second part extending rearward with respect to the first part in a fore-to-aft direction. The first part is at least partially disposed in a non-overlapping location with respect to the outboard motor and the bulwark as viewed from a side view of the outboard motor boat. The second part extends along a lateral portion of the outboard motor.
