Trimmscheibe
Speed is not witchcraft but a consequence of the optimal adjustment of sail and rig. The trim tab provides racing and touring sailors with guidelines for the greatest possible propulsion of their boat.
The complex interaction of wind and wave is taken into account by the special division of the trim tab. The 12 most important trim points for each condition can be read at a glance.
The handling of the trim disc is very simple as only the prevailing wind-wave segmentation has to be set. Then the individual guide values for foresail and mainsail can be read directly on the corresponding courses. 
Designed and tested by professionals.
