The base frames and rests upon the floatation device. The benches include bench boards attached above and parallel to the floatation device. The tabletop supports are attached between the benches. The tabletop includes top boards. The battery is mounted on the base under the top boards. The motor is mounted at one end with a retractable keel located adjacent to the opposite end.

A foil assembly for a watercraft includes a base assembly, a fin rotatably connected to the base assembly such that the fin can rotate longitudinally, and a slider attachment configured to connect to a fin box of a watercraft wherein the base assembly is configured to be removably disposed within the slider attachment such that the base assembly and the fin can be removed and rotated laterally to a folded position and still be retained by the slider attachment to the fin box.

The invention relates to a floating maritime vessel including at least one hull beneath a deck, the hull extending between a bow and a stern in a longitudinal direction of the vessel, the vessel including, on its lower part, a removable keel and, on its upper part, a conning tower erected above the deck, the keel being able to be descended below the hull and raised back through the hull, the keel including a lower end and an upper end, the upper end of the keel connecting to the hull when the keel is in its lowered position. According to the invention, the conning tower contains a keel-storage space and the keel and the keel-storage space of the conning tower are aligned such that the keel can be raised by upward translation at least partly into the keel-storage space of the conning tower.

Maritime drone (1) comprising a hull (2) provided with an upper face (3) and a lower face (4), a centerboard (5) extending projecting from the lower face (4) of the hull (2) in order to give sailing/navigation stability to the maritime drone (1) and at least one wing sail (6). The wing sail (6) comprises a mast (7) connected to the hull (2) and a wing profile (8) connected to the mast (7) and it is suitable to intercept the wind in order to move the maritime drone (1). The centerboard (5) internally defines a containment volume (9) for the wing sail (6), which is movable between an operative position, in which it extends at least partially above the upper face (3) of the hull (2), and an inoperative position, in which it is at least partially housed in the containment volume (9) of the centerboard (5).

Disclosed is a surface vessel with motorised mechanical propulsion including a fusiform hull and a keel in the bottom part of the hull, the hull having an elongate shape in a longitudinal direction of the vessel, the keel including, at the bottom end of same, a bulb linked to the hull by a linking part of the keel, the maximum width of the linking part being smaller than the maximum width of the bulb, the maximum length of the linking part being smaller than the maximum length of the bulb, the lengths and widths being considered respectively in the longitudinal direction of the vessel and a horizontal transverse direction perpendicular to the longitudinal direction. The hull has a total width to total length ratio of less than 0.2 and a maximum length of less than 20 metres.

Disclosed is a motorised wave-piercing ship with hull with a deck, the ship including a conning tower and, under the hull, a weighted keel, the keel being removable and being able to be placed in a low position and a high or extracted position. According to the invention, the ship can sail as a monohull or as a trimaran, the hull including a device for removable attachment of an anti-roll stabilisation system including an elongated connection arm terminated at its two lateral ends by two floats, the connection arm including an attachment member, the attachment member being configured to be removably attached on the attachment device in order to transform the ship into a trimaran, and the ship is monohull in the absence of the anti-roll stabilisation system.

A submersible vessel having wing and keel assemblies that are extendable for wind-powered surface operation and retractable to reduce drag for submerged operation or to place the vessel in a more compact configuration. A deployment mechanism including an actuator and linkage pivots the wing and keel assemblies-simultaneously between the deployed and retracted configuration. The vessel may have first and second pressure hulls flanking the wing and keel assemblies. A drive mechanism including a motor and a gear train employing pulley-and-cable assemblies rotates either the wing and flap together such that the flap angle relative to the wing is constant, or to change the flap angle relative to the wing with the wing angle of incidence held constant. The invention also provides a retractable wind-powered propulsion apparatus that is mountable to the hull assembly of a submersible or non-submersible vessel.

A sailing yacht (I) comprising a hull (S) and two drift blades (1,1) coupled to said hull (S), each of said drift blades (1,1) being fixed pivoted to said hull (S) in a symmetrical position with respect to the other blade (1, 1) from opposite side with respect to the longitudinal axis (X) of said hull (S) for rotating independently relative to the other blade (1,1) about a rotation axis (Y,Y) not necessarily parallel to said longitudinal axis (X), and around a rotation vertical axis (R, R) so as to modify the angle of incidence with respect to the flow line of the water, with the possibility when sailing of having ballast (Z,Z) positioned in various positions dynamically modified: each ballast (Z, Z) attached to the respective blade (1,1) and separated; both ballasts (Z, Z) attached to one drift blade (1); both ballasts (Z, Z) attached to the other drift blade (1); both ballasts (Z, Z) attached to said two drift blades (1, 1) and joined.
