A watch app to support the yacht racing tactician.
Any bugs or questions, please use the "Contact Developer" at the right or below or our FaceBook page https://www.facebook.com/RaceQs-Watch-App-Beta-1686063161677280.
This app assists you with the two fundamental questions of sailboat racing: "When to tack?" and "Which heading to steer?" plus an intuitive, accurate and customised countdown timer.
We have distilled years of high-level yacht racing experience, software development and on-water testing to create a set of algorithms that analyse your boat's track and presents the results in a clear and intuitive user experience on your wrist. 
"When to tack" is dependent on your course, wind shifts and lay lines.
"Which heading" is dependent on your course, mark location, wind and current.

Fenix 5 users: There's a Garmin glitch that is causing menu headings to read "English". It was been analysed as a bug in F/W update 15.10 in mid December and we're awaiting a fix. Sorry about that.
Vivoactive-3 users: There's currently a glitch in the Garmin release process that means you'll need to use Garmin Express on your computer to update the firmware on your watch to 7.2 .
