Stern ramp launch and recovery system for launching, and recovering, a daughter boat from a stern of a mother ship, the system (1; 101) comprising a main frame, a landing frame for supporting the daughter boat, a first translation guiding structure, a second translation guiding structure, and a translation movement mechanism, wherein the system is configured to be in an operation condition, in which the system is forming a telescopic stern ramp of the mother ship, said telescopic stern ramp having an inclined stern ramp length axis having a descending slope in rearward direction of the mother ship, and in which operation condition: - the first translation guiding structure is attached to the mother ship along the stern, whereby the first translation guiding structure defines said inclined stern ramp length axis, as well as a corresponding stern ramp width axis, of said telescopic stern ramp; - the main frame is held by the mother ship and by the first translation guiding structure in a first reciprocally translatable manner along said inclined stern ramp length axis, said first translatable manner being relative to the stern; - the landing frame is held by the main frame and by the second translation guiding structure in a second reciprocally translatable manner along said inclined stern ramp length axis, said second translatable manner being relative to the main frame; - the translation movement mechanism is configured to effect and to control movements according to said first reciprocally translatable manner and said second reciprocally translatable manner; and - said first reciprocally translatable manner and said second reciprocally translatable manner are allowing the landing frame to reciprocally translate between at least one telescopic retracted position and at least one telescopic extended position, wherein the landing frame in its telescopic extended position is farther descended along said inclined stern ramp length axis than in its telescopic retracted position; characterized in that the system further comprises a rotation guiding structure (6, 51, 62; 106, 51, 162, 107) and a rotation movement mechanism (22; 122), wherein in said operation condition: - the landing frame is held by the main frame and by the rotation guiding structure in a reciprocally pivotable manner relative to the main frame, about a pivot axis being parallel to said stern ramp width axis, between said telescopic extended position of the landing frame and at least one boat landing pivot position in which the landing frame has less inclination as compared to the inclined stern ramp length axis; and - the rotation movement mechanism is configured to effect and to control movements according to said reciprocally pivotable manner. - the first translation guiding structure is attached to the mother ship along the stern, whereby the first translation guiding structure defines said inclined stern ramp length axis, as well as a corresponding stern ramp width axis, of said telescopic stern ramp; - the main frame is held by the mother ship and by the first translation guiding structure in a first reciprocally translatable manner along said inclined stern ramp length axis, said first translatable manner being relative to the stern; - the landing frame is held by the main frame and by the second translation guiding structure in a second reciprocally translatable manner along said inclined stern ramp length axis, said second translatable manner being relative to the main frame; - the translation movement mechanism is configured to effect and to control movements according to said first reciprocally translatable manner and said second reciprocally translatable manner; and - said first reciprocally translatable manner and said second reciprocally translatable manner are allowing the landing frame to reciprocally translate between at least one telescopic retracted position and at least one telescopic extended position, wherein the landing frame in its telescopic extended position is farther descended along said inclined stern ramp length axis than in its telescopic retracted position; - the landing frame is held by the main frame and by the rotation guiding structure in a reciprocally pivotable manner relative to the main frame, about a pivot axis being parallel to said stern ramp width axis, between said telescopic extended position of the landing frame and at least one boat landing pivot position in which the landing frame has less inclination as compared to the inclined stern ramp length axis; and - the rotation movement mechanism is configured to effect and to control movements according to said reciprocally pivotable manner.
