A gate system for a pontoon boat is provided. The gate system may comprise a gate, a guide, and a guide interface member.

Sun heats dark continents more than reflective oceans. Air moves onshore from high pressure to low. Creating wind: powering weather and storms—“hurricane-in-a-box-on-water” principles producing electricity in a marine vessel, providing Green Technology for Marine Transportation. Captured and recovered heat, offset by loss of heat, creates differential pressure conditions across multiple rotary engines. Night and day, a working fluid moves from high pressure to low; powering alternators, batteries, domestics, and in-hull electric drive trains, in a unique, lightweight exoskeleton dome shell design vessel. Disclosed vessel design advantages include: high energy collection and living space to vessel length ratio; high strength to weight ratio; high carrying capacity, downwind sailing while producing electricity; modular fabrication and shipping; and sustained hull speed in a vessel harvesting energy from the environment. The longer the vessel: the more it carries: the greater the hull speed: the faster it goes.

Apparatus and methods for recovering watercraft. A ramp is movable relative to a stationary carrying apparatus between a recovering position and a parked position. The ramp includes a frame and a deformable body, which is fastened to the frame. When the ramp is in the recovering position, the deformable body points toward the watercraft to be recovered and is located at least partially above the water surface. The watercraft travels onto the ramp and deforms the deformable body from above. The watercraft is pulled out of the water and moved onto the carrying apparatus.

A powered water vessel includes a unitary section of the bow that is pivotably rotatable about a horizontal axis thereby permitting a closed-bow configuration and an opened-bow configuration. The closed-bow configuration is generally amenable to regular boat operations, while the opened-bow configuration is generally amenable to loading and unloading passengers, vehicles and/or cargo. A folding ramp assembly is extendable through the open-bowed configuration for loading and unloading, with track extensions providing additional extension distance.

A marine vessel door system implemented within or on a marine vessel gunwale, wherein the door can be easily opened to allow easy loading or unloading of passengers and cargo and closed in order to prevent passengers and cargo from entering or exiting the vessel. The marine vessel door system includes a door body and a door-moving mechanism which translates the door body frontward and rearward aligned to the marine vessel gunwale. The door-moving mechanism can include an articulated parallelogram attached to a fixed structure of the marine vessel and carrying the door body such that the door body translates forward and rearward jointly with a movable part of the articulated parallelogram.

A system for the recovery of a surface marine craft by a carrier ship includes a lifting device with which the carrier ship is intended to be equipped and which includes a lifting unit of the davit type, equipped with a lifting cable including, at one end, a connection interface, a pole bearing a guide cable, an anchor connected to one end of the guide cable, the connection interface for the lifting cable being coupled removably to the anchor, and a hauling cable. The system also includes a receiving device with which the marine craft is intended to be equipped, the receiving device including a forward module.

The present invention relates to a submerged-floating type water house. The house comprises: a first lower side part and a second lower side part formed symmetrically with respect to each other; a first upper side part and a second upper side part formed symmetrically and extending from the first lower side part and the second lower side part; and a front part and a rear part formed in front of and in back of the first lower side part and second lower side part and the first upper side part and second upper side part, thereby forming a rhombic-shaped body and floating in water.
