The control system is connected to a traveler on a closed circuit and ensures efficient control and a clean layout for systems such as the mainsail sheet.
Line drivers mount a self tailing sheave which operates in both direction with a textile rippingsystem that is efficient even if the circuit is not under strain and causes no wear in the rope. A clutch pin sets the direction in which the traveler moves, or allows for it to be locked in the required position. The power ratio obtainable with a normal (250 mm) handle is 8 to 1, which is much better than a tackle can offer; moreover, this system has a very limited size and weight.
