<p>A winding arrangement suitable for sheeting in a sail of a yacht comprises a winch drum (2), a handle (6) for rotating the winch drum, coupling means (30) operable in a first mode to connect a hydraulic pump/motor (15) to the handle to act as a pump driven by the handle, and operable in a second mode to connect the hydraulic pump/motor to the winch drum to act as a motor driving the drum, and control means (40, 41, 61) for changing the coupling means from the first mode to the second mode and vice versa. It is therefore possible, by operating this winding arrangement in the first mode, to rotate the winch drum manually so as to wind in a sail sheet or line attached to the winch drum, and at the same time to drive the pump to charge up a hydraulic accumulator (28) or pass hydraulic fluid to another similar winding arrangement operating in the second mode either directly or through a hydraulic intensifier (33). When the coupling means is operable in the second mode one or more similar winding arrangements may supply hydraulic fluid to the pump/motor either directly or through the hydraulic intensifier (33).</p> |
