An entertainment barge includes at least two pontoons, a first deck having a front, rear, right side and left side, is attached to both pontoons. A second deck is disposed above and substantially parallel to the first deck. At least two retractable spuds are attached to the deck and are adapted to be lowered into the water to secure the barge in a fixed position.

A combination recreation vehicle and houseboat having an upper enclosure assembly and a lower floating chassis assembly with a floor system portion, wherein the upper and lower assemblies are movable between a retracted condition and an extended condition independently of each other.

A privacy enclosure separate from the vessel hold and having at least one entranceway accessible from outside the hold of the vessel.

A privacy enclosure separate from the vessel hold and having at least one entranceway accessible from outside the hold of the vessel.

A method of creating a pair of cabins comprising: a first cabin; a second cabin; wherein the first cabin and the second cabin are adjacent to each other and are defined by a plurality of outer walls defining a substantially rectangular area containing the first cabin and the second cabin; wherein the first outer wall meets the second outer wall at a ninety (90) degree angle, the second outer wall meets the third outer wall at a ninety (90) degree angle, the third outer wall meets the fourth outer wall at a ninety (90) degree angle, and the fourth outer wall meets the first outer wall at a (90) degree angle; the first cabin and second cabin also sharing a common wall separating the first cabin from the second cabin; and wherein the common wall is operatively connected to an outer wall at an angle other than ninety (90) degrees.

A pleasure craft is provided such as a luxury pleasure craft. The craft eliminates the need for transverse bulkheads in one or more decks inside the hull of the craft, thus improving the aesthetics and usability thereof. The hull of the pleasure craft defines an imaginary or virtual freeboard deck located below the main deck of the craft. A cavity is arranged on one or more decks on both sides of the hull separate from the remaining space of the corresponding deck and delimited on its outer side by the corresponding side wall. The imaginary or virtual freeboard deck is therefore at a height equal to the extension in the vertical direction of the cavities from the floor of the corresponding deck.

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.

A butt joint octagonal frustum type floating production storage and offloading (FPSO) system, wherein a floating body is provided with an upper structural body in an octagonal frustum shape and a lower structural body in a regular octagonal frustum shape; in a combined state, a smaller bottom surface of the upper structural body is fixedly connected with a smaller bottom surface of the lower structural body, to form a junction surface; the axis of the upper structural body and the axis of the lower structural body are positioned on the same straight line; the larger bottom of the upper structural body acts as an upper deck of the floating structure and the larger bottom of the lower structural body acts as a lower plate underwater of the floating structure; the junction surface is a full-load waterplane of the floating structure.
