A harness device for attaching a towing line (17) to a surfboard (20) has an automatic release mechanism which operates to disconnect the surfboard from the line if the surfboards should turn over or become inclined to the length of the line by more than a predetermined threshold angle. The automatic release mechanism includes an enlarged head (18), for example, spherical or cylindrical, which is lodged into a coupling socket (14) in the underside of the board, the socket having a narrow mouth or lip (15) behind which the head lodges if the inclination of the line to the general plane of the surfboard is sufficiently small, while allowing the head to disengage from the socket if this inclination increases to an angle beyond the threshold inclination. Handles joined to the towing line may also be incorporated into the harness. |
