No more mathematical calculations. Plan your race with certainty. If it´s rough weather and you cannot see the gybe mark, the wot-tac will tell you what to steer. No more getting to the windward mark and following the pack. Using the wot-tac you can be confident of getting the numbers right.

Wot-tac is boat shaped with a compass on the bow and a centrally mounted dial etched with 360º markings. On the top of the etched dial is an arrow that can be used when the wind shifts.
