A system for deploying and recovering an autonomous underwater device (AUD) using a surface carrier ship, includes, in addition to the carrier ship, a subaquatic vehicle (SV) guided by a connection wire connected to the carrier ship, the SV able to be positioned in a storage configuration wherein the SV is fixedly but removably joined to the carrier ship in a storage zone, or in a configuration for use, in which the SV, separated from the carrier ship, is in the water and at a distance from the carrier ship while remaining connected by the connection wire, the SV including propulsion, guiding and stabilizing systems and a station for receiving the AUD allowing it to be removably attached to the SV, the receiving station and the AUD including a complementary automated docking unit allowing the AUD to automatically dock with the receiving station during recovery and attach itself thereto.

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.

This invention provides improvements in the efficiency of a sailing vessel through the use of flaps, hydrofoils, or members on the keel of a sailing vessel. One or more are positioned at the top, or root of the keel of the vessel, which primarily generate a force in the windward direction to provide a counter-leeward drift force. One or more are located at the bottom, or tip of the keel of the vessel, which primarily generate a force in the leeward direction to provide a counter-heeling moment. Among other benefits, operation of these flaps, hydrofoils, or members during sailing increases the vessel's efficiency, in particular its velocity made good. Further, since they are mounted on one appendage, sailing vessels of a rudder and keel design can be equipped with counter leeward-drift and counter-heeling attributes without the need for additional appendages.

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.
