The invention relates to a device for recovering a vessel (N) at sea from a surface station, the recovery device comprising: - a cradle (B) with negative buoyancy for supporting the vessel (N), - a lifting device (LEV) comprising an upper frame (CS) and a hanger assembly (11, 12, 13, 14, 15, 16) connecting the cradle (B) to the upper frame (CS), the lengths of the hangers being variable so as to allow the cradle to be hoisted and lowered (B), a guide float (F) capable of having a predetermined positive buoyancy, the guide float (F) being interposed between the cradle (B) and the upper frame (CS) so that the cradle (B) is intended to support the guide float (F) during the hoisting of the cradle (B), the guide float (F) being connected to the cradle (B) and configured to guide the vessel (N) moving at the surface of the water with a displacement speed, comprising a positive component along an x-axis, linked to the upper frame (CS), to a front portion of the guide float (F) when the guide float (F) has the predetermined positive buoyancy, the guide float (F) being in connection with three degrees of freedom in rotation with the cradle (B).
