Motor boat comprising a support structure and at least one pair of similar foils arranged on each side of the support structure, each of said foils being defined by a wing and its support; the latter being retractable into the lower part of the structure and mounted so as to be slidable relative thereto; said foils being arranged so as to adopt at least two fixed positions, namely an “active” position in which they are deployed in similar positions and a “passive” position in which said supports are retracted into the support structure; characterized in that the boat is adapted such that the deployment of the foils comprises an initial movement of the supports in a substantially horizontal direction away from the vertical median plane of the support structure, followed by a tilting about an axis parallel or substantially parallel to the main axis of the boat.

A watercraft comprises a vehicle payload bay; a sail connected to the payload bay for propelling the watercraft in a foiling mode; and three or more hydrofoils connected to the payload bay. The hydrofoils are configured to provide control of the roll, pitch, and yaw of the watercraft and to elevate the vehicle payload by above a water surface when the watercraft is in the foiling mode. The hydrofoils can also provide control of roll, pitch, yaw, and elevation of the watercraft during the transition from a prone mode to a foiling mode. A mechanical propulsive system can be used for propelling the watercraft at least during transition from the prone mode to the foiling mode. The watercraft may not include a hull such that during the transition from the prone mode to the foiling mode, pitch and roll control are not substantially provided through the actions of gravity and buoyancy.

A posture control system for a hull, and a marine vessel including the posture control system, allows crew members to fish more comfortably and includes a posture control tab attached to a stern of the hull to control a posture of the hull, a driver to drive the posture control tab, and a controller to control the driver. When it is determined that the hull has changed to a fishing mode, the controller causes the driver to raise the posture control tab to a predetermined position.

A boat stabilizer having an upper harness for attachment to a vessel, the upper harness having an assembly control system for controlling attached wing assemblies, each wing assembly having a wing attached to the assembly control system and a wing mount attached to the wing and the assembly control system. The boat stabilizer may be further comprised of a controllable parasail comprising a parasail canopy, a plurality of parasail cords attached the parasail canopy, a parasail mount attached to the upper harness and the parasail cords, a parasail control rudder attached to each parasail cords, and yaw and pitch controllers, both of which are attached to the parasail control rudder. The assembly control system is configured to work in conjunction with the controllable parasail to provide the desired balance of vertical lift and forward propulsion to the attached vessel, while also providing directional control to the attached vessel.

The invention relates to a method for constructing and/or manufacturing a water sports device (2) which has a modular structure comprising a floating body (4). The modules can be connected together via interfaces and are connected during operation. In particular, the invention relates to a method for constructing and/or manufacturing a foilboard or driver propulsion vehicle, wherein a server device is provided, and a program-controlled input interface is provided for user-defined inputs on a terminal (5), in particular a mobile terminal, which is arranged at a distance from the server device in particular. The modules are imaged in a computer program of the server device and/or of the terminal (5), and at least one outer contour of the floating body (4) of the water sports device (2) can be, in particular, freely defined by the user. On the basis of the outer contour of the floating body (4) defined in the program, automated manufacturing information is produced, and the floating body (4) manufactured according to the production information can be combined with another module, in particular multiple other modules, to produce the water sports device (2). The invention also
