An easily assembled highly portable watercraft comprising a modular boat system that seats one or more operators and is comprised of four or more pontoons connected to downward-sloping diagonally-placed outrigger beams with attached stiffeners connecting to a bridge-deck. The portable watercraft can be rowed, poled, propelled by fins or propellers, and sailed, for example, by an operator situated on the bridge-deck. The pontoons, outriggers, bridge-deck, and other aspects are easily interchangeable to conform to numerous configurations making a custom watercraft that is tailorable to varying water conditions.

This invention is directed to a column floater with extended cylinder and a ring buoy-group, which comprises an upright buoy at a water surface, an extended cylinder, a positioning system and a topsides. The top of the upright buoy is above the water surface and a moonpool is either set or not in the center of the upright buoy through the top to the bottom. The extended cylinder, connecting to the bottom of the upright buoy and extending downwards, includes two types of fixed and sliding to form a column floater with fixed extended cylinder and a column floater with sliding extended cylinder respectively. The positioning system is one or two combined of mooring system and DP system. The column floater with extended cylinder is a new type floating platform with multi-purpose, combining advantages of the spar platform and the current cylindrical FPSO, high performance, safety and reliability.

A computer-implemented method, computer program product, and computer system may include determining, by a computing device, a first location on a body of water. The first location may be transmitted to a drone buoy. Data may be received from the drone buoy. A second location on the body of water to send to the drone buoy may be determined based upon, at least in part, the data received from the drone buoy.

Provided is a portable foldable aquaplane, comprising a buoyancy device (9), a handle (2), a pedal board (3) and a seat cushion (5), wherein the buoyancy device (9) comprises a head buoyancy component (1) and a body buoyancy component (13); the head buoyancy component (1) is connected to a front end of the body buoyancy component (13) in a foldable manner; the handle (2) is connected to the head buoyancy component (1) via a first telescopic rod (14); and the seat cushion (5) is connected to the body buoyancy component (13) via a second telescopic rod (15). By adjusting the height of the handle (2) and of the seat cushion (5), the aquaplane is not only capable of satisfying the requirements of riding on water in a standing state, but is also capable of satisfying the requirements of riding on water in a sitting state. The foldable structure of the aquaplane makes it easy to carry and store, and same can also provide sports and entertainment for both individuals and multi-players at the same time by means of a connection hook.

There is provided an assembleable boat made of fiber-reinforced plastic (FRP) including a bottom wall assembly; a left side wall assembly; a right side wall assembly; and a front wall assembly. the bottom wall assembly, the back wall assembly, the left side wall assembly, the right wall assembly, and the front wall assembly are mechanically connected to form the assembleable boat; and each of the bottom wall assembly, the left side wall assembly, the right wall assembly, and the front wall assembly is made of FRP.

The present invention discloses a water skateboard apparatus, including a loading component and a number of skateboard bodies that are pushed forward together, where a number of the skateboard bodies are spaced apart, and the loading component is detachably connected to top surfaces of a number of the skateboard bodies. The water skateboard apparatus of the present invention greatly increases the loading space of the water skateboard apparatus by the loading component having a sufficient loading space. The propulsion power of the water skateboard apparatus is greatly improved by providing power through a number of the skateboard bodies. At the same time, the loading component and a number of the skateboard bodies can be installed and disassembled, which is convenient for transportation, maintenance and replacement.

There is provided a folding boat structure for facilitating transportation, the structure comprising: a central structure having a fixed primary hull; outrigging supporting at least one secondary hull structure having a secondary hull to the central structure, wherein: the outrigging is double hinged so as to be user configurable in a deployed configuration and a stowed configuration and wherein: in the deployed configuration, the at least one secondary hull is located laterally adjacent the main hull and downwardly orientated; and in the stowed configuration, the at least one secondary hull is located above the main hull and upwardly orientated.

A tipping bow has at least one articulated connection to a vessel behind and is connected to an anchoring. The tipping bow has a structural member attached to one or more attachment points at the bottom edge of the tipping bow. The anchoring is attached to an anchor attachment positioned behind and lower than the balance point of the tipping bow.

A collapsible watercraft comprises a foldable sheet and is transitionable between a deployable kayak configuration and a stowed configuration by folding or unfolding along predefined fold lines in the foldable sheet. In the kayak configuration, the watercraft is switchable between at least a single-seat configuration and a tandem configuration by installing a desired number of seat and footrest assemblies. At least some of the seat and footrest assemblies are installed in the kayak by strapping seat and/or footrest components to loops nonreleasably attached to removable floorboards of the kayak. The removable floorboards are installed in the kayak using extruded engagement profiles.

A collapsible kayak may include a single-piece hull including a plurality of crease lines along which the hull is foldable. A floorboard lines a midship portion of the hull between a bow portion and a stern portion, and the floorboard includes a base and a pair of outboard walls permanently fixed at distal ends to port and starboard gunwales of the hull. The bow, stem, and midship portions are configured as a tri-fold, such that the bow portion and the stern portion of the kayak are foldable toward each other to overlap the midship portion of the hull when collapsed.
