For the dinghy sailor the wot-tac will predict the correct start line bias, and the compass courses to be sailed in an Olympic or Trapezoidal type courses.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.
