An apparatus and methods according to the present invention provides a human powered catamaran-styled watercraft and methods of configuring and operating the watercraft. The watercraft generally comprises at least one hull in communication with a folding collapsible frame, wherein in the frame comprises a center rack pivotally joining hulls of hull sets to provide for common pivoting of the hulls during articulation of the watercraft, thereby the hulls and frame are in further communication through a at least one pivot pad which provides for slidable pivoting of the hulls during articulation of the watercraft. A method of folding and reversibly extending the watercraft to provide for optimized storage is provided. A method of operation of the watercraft to provide for articulation of the watercraft is provided.

A method to rapidly form a reconfigurable multihull multiplatform floating vessel includes installing a plurality of pin connectors on a plurality of longitudinal hulls, installing a plurality of joints on the plurality of longitudinal hulls, positioning the plurality of longitudinal hulls with the plurality of pin connectors and the plurality of joints proximate each other, mounting a first moveable planar platform having a first end and a second end with the first moveable planar platform mounted a preset distance above a load line of the first longitudinal hull, mounting a second moveable planar platform having a first end and a second end, forming a platform void extending between pairs of moveable planar platforms to provide increased safety for equipment and personnel on the moveable planar platform by preventing impact together of longitudinal hulls, and forming a hull void extending between pairs of longitudinal hulls.

A catamaran oil production apparatus is disclosed for producing oil in a marine environment. The apparatus includes first and second vessels that are spaced apart during use. A first frame spans between the vessels. A second frame spans between the vessels. The frames are spaced apart and connected to the vessels in a configuration that spaces the vessels apart. The first frame connects to the first vessel with a universal joint and to the second vessel with a hinged connection. The second frame connects to the second vessel with a universal joint and to the first vessel with a hinged or pinned connection. At least one of the frames supports an oil production platform. One or more risers or riser pipes extends from the seabed (e.g., at a wellhead) to the production platform (or platforms). In one embodiment, the production apparatus includes crew quarters.

A watercraft comprising: a first section; a second section; and a connecting element joining the first section to the second section, wherein the connecting element has a first unextended state and a second extended state, and wherein the connecting element can be moved between the first and second states to alter the relative positions of the first and second sections.

A catamaran (100) which has a center tunnel (102), the opposite sides (105a, 105b) of which form asymmetrical pontoons (106a, 106b), which are mirror images of each other, and which pontoons (106a, 106b) have buoyancy, which has been adapted so that when the catamaran (100) moves in water, the center tunnel (102) functions as a combined water and air tunnel. When the catamaran (100) is stationary in water, the ceiling (108) of the center tunnel (102) is in water. The ceiling (108) of the center tunnel further curves in a cylindrically convex manner downwards when going from the bow (116) to the direction of the stern (118) only after an essentially horizontal portion (401) of a distance (d), which essentially horizontal portion (401) is located between the pontoons (106a, 106b).

There is provided a renewable power generation farm for fishing work, the farm comprising: a plurality of mutually connected floating ships, wherein each ship is configured to generate an energy using solar and wind power, wherein each ship comprises: a main elongate floating structure; a wind-based energy generation device secured to the main elongate floating structure; a transverse beam extending perpendicularly to a longitudinal direction of the main structure; a longitudinal beam extending in a parallel manner to the longitudinal direction of the main structure; connection beams connecting both opposing ends of the transverse beam and both opposing ends of the longitudinal beam respectively; auxiliary pillars vertically extending through the both ends of the transverse beam and the longitudinal beam respectively; solar-based energy generation devices disposed at top ends of the auxiliary pillars respectively; and auxiliary elongate floating structures disposed at bottom ends of the auxiliary pillars passing through the ends of the transverse beam.

A multihull multiplatform floating vessel with a plurality of longitudinal hulls, a plurality of pin connectors; each pin connector providing one axis motion, a plurality of joints, each joint providing two axis motion, wherein the first joint is mounted on one hull the second joint is mounted on a second hull and wherein one group of pin connectors is mounted on one hull and a second group of pin connectors is mounted on the second hull. A first moveable planar platform is connected to the hulls and a second moveable planar platform is connected to the hulls by the pin connectors and joints, the platforms spaced apart from each other forming a platform void between pairs of platforms, and a hull void between pairs of hulls increasing safety onboard and decreasing motion of the moveable planar platforms as mounted to the longitudinal hulls.

Two watercraft are connected together using a hinge system. A knuckle in one watercraft is placed in a corresponding space therefore in a second watercraft. Similarly, a buttress in the second watercraft is placed in a corresponding space in the first watercraft. An axle is placed within the buttresses as well as within the knuckle to attach the hinge device to attach the two watercraft together. This axle is also attached to a rear transom and to a forward bow connector. A second axle adds further rigidity to the system as it attached through a first watercraft passageway to both the transom and to the bow connector.
