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 sailboat is described having a boat hull (1), two flow profiles (2, 3) protruding laterally from the boat hull (1), and at least one underwater hydrofoil (16). To be able to achieve high travel velocities while maintaining the stability of the sailboat and balanced control behavior, it is proposed that the flow profiles (2, 3) protrude outward in a V shape from the boat hull and each have an aerodynamic stabilizer forming an aerodynamic aileron (4, 5), and/or the at least one underwater hydrofoil (16) is provided with a hydrodynamic stabilizer forming a hydrodynamic aileron.

A structure for stabilizing a barrel on a pontoon vessel includes a deck structure. First And second hull frame members are affixed to the deck structure and extend therealong. In spaced relationship to each other. A first and second conduit extends along a respective hull frame member; the first conduit being spaced from the second conduit by a distance to receive a portion of a barrel therebetween and each conduit contacting the barrel above a barrel central line. A strap having a first end anchored near the first conduit, and tracing a path from the anchor beneath, and in contact with, the barrel disposed between the first conduit in the second conduit, along the second conduit, and returning to the first conduit by tracing a path from the second conduit to the first conduit beneath and in contact with the barrel. The strap having a second end anchored near the first conduit.

An offshore platform lifting device for lifting operations at sea after sailed to a certain position of a sea surface includes an upper deck, a plurality of upright columns, a rail seat, a base disposed on the rail seat, two davit arms, two first winches, and two second winches. The upper deck has a lower pontoon. The upright columns are connected between to the upper deck and the lower pontoon. Each upright column is provided with a support leg that is longitudinally inserted through the upright column, thereby positioning the offshore platform lifting device on the seabed through the upright columns. The two davit arms are disposed the base and drives the base to move laterally through a pushing device. The two second winches each have a second cable passing through the two davit arms. A hook is disposed at a distal end of the second cable.
