A hoist system and a method for lifting and lowering an object such as a boat include a support structure, a support member supported by the support structure and a hoisting assembly. The hoisting assembly includes an attachment assembly and a set of at least three flexible members operably coupled to the support member and the attachment assembly to retract and extend the attachment assembly vertically relative to a reference axis. The hoisting assembly is supported by the support structure and configured with the support member so as to space apart the flexible members from each other, and wherein each flexible member defines an oblique angle with the reference axis parallel to the vertical reference axis.

A system for the recovery of a surface marine craft by a carrier ship includes a lifting device with which the carrier ship is intended to be equipped and which includes a lifting unit of the davit type, equipped with a lifting cable including, at one end, a connection interface, a pole bearing a guide cable, an anchor connected to one end of the guide cable, the connection interface for the lifting cable being coupled removably to the anchor, and a hauling cable. The system also includes a receiving device with which the marine craft is intended to be equipped, the receiving device including a forward module.

A lifeboat launch control system. The lifeboat launch control system has a wheel trunk that runs along the side of a ship. An axle box is vertically movable in the wheel trunk. The axle box has a pair of wheels on opposing sides of a bar. A shaft is removably inserted into the bar. The shaft is removable from the bar by a handle. When the shaft is removed from the bar, the lifeboat is released from the ship.

Disclosed is a measurement system for aquatic environments, including a surface vessel and a submersible device, the submersible device including a hull, propulsion, guide, and sensors for taking measurements. The submersible device can either be launched from the vessel in order to then maneuver underwater independently of the vessel during a remote deployment phase, or be stored in a vessel during a non-deployment phase, the vessel including at least one hull and propulsion and guide, the at least one hull of the vessel including a submerged portion located below a waterline. The submerged portion of the at least one hull of the vessel includes a recess designed to receive at least an upper portion of the hull of the submersible device when the latter is stored in the vessel, the recess being arranged entirely below the waterline so that the submersible device remains completely submerged during storage.
