A truly revolutionary device that is essential for all sailors who race competitively. As well as predicting start line bias it will predict wind angles and, more importantly for windward/ leeward sailors, it will predict whether a gybe set or bear away set is preferred.
It is a simple boat shaped device that does a number of different things to assist the keen racing sailor. The innovative part of the design uses reverse degree markings and because the wot-tac is hand-held it is easy to use and can easily be stored in a jacket pocket, buoyancy aid or simply hung round your neck with the lanyard supplied.
Using the wot-tac is simple:
- First, find the bearing of the true wind direction.
- Second, set the bearing into the dial, which clicks every five degrees; and then,
- Move the pointer arm to the same bearing.
Wot-tac is ready! Use it once you’ll never sail without it.
