Jibing

In the second generation Wiebel rig, the way in which the boat changes tack has been improved. The boat is designed to jibe. During the jibe, the boom swings over the bow over an angle of more than 270 degrees.

 In the second generation Wiebel rig, the way in which the boat changes tack has been improved. The boat is designed to jibe. During the jibe, the boom swings over the bow over an angle of more than 270 degrees. At the same time the mastfoot travels from left to right or vice versa along the curved rail at the forward edge of the frame. The mastfoot is operated by winch. 

This makes it possible to keep the gap underneath the sail minimal during sailing. This in turn results in the socalled "endplating" effect, preventing leakage under the sail and increasing the pressure in the sail, resulting in the ultimate sail. Hence the optimal position of the sail as it is known from windsurfing, i.e. with very little or no gap underneath the sail, is always reached.
