Abstract: A mooring buoy includes a first floating body, a second body slidingly connected to the first and normally submerged, a mooring line connected to the second body by a connector housed in a seat in the first body and movable between a retracted position and a protruding position, enabling fixing the mooring line. The buoy further includes at least one chamber, in one or both of the first and second bodies, a fluid circuit admitting fluid into and out of the chamber, and a control unit connected to the fluid circuit. The control unit controls the fluid circuit to vary the amount of the fluid in the chamber, causing a variation of the immersion depth of the first body with respect to the second body or vice versa and, consequently, movement of the connecting element between the retracted and protruding positions.
