Hauling system involving a captive sail and a flying mooring line

A captive wing traction system (1) comprising;

• a traction wing (5) to generate a traction force because of the effect of the wind and is deployed and folded relative to a base platform (3) that is provided with a stowage mast (4), the traction wing (5) having a leading edge (16) and a trailing edge (17),
• a trajectory control flying device (7) attached to the traction wing (5) by fixed suspension lines (6) and mobile suspension lines (6b), the trajectory control flying device (7) controls the mobile suspension lines (6b);
• a traction line (8) connecting the trajectory control flying device (7) to the base platform (3);
• a guide line (9) that connects the leading edge (16) of the traction wing (5) to the trajectory control flying device (7);
• a stowage line (10) one end of which is connected to the base platform (3) and that is connected in a sliding manner to the guide line (9) by a slider (15) fixed onto the stowage line (10) and with a pivoting sliding connection to the guide line (9);
• a deflector element (13) that is attached to the stowage mast (4) and through which the stowage line (10) is routed between its first end and its connection to the guide line (9).
