SailTimer: Optimal Tacks and TTD®

Sailboats often tack to their destination, which affects the distance and travel time.  The SailTimer™ tacking calculations were developed beginning in 2005 because GPS chartplotters didn't know how far your tacking route would be.  But if they didn't know that distance, how could they calculate the ETA correctly?  The SailTimer tacking results solved this problem, and set a new standard.

The SailTimer app provides an instant display of your optimal tacking route, distance and Tacking Time to Destination (TTD ®). It can also learn polar plots for your individual sailboat's performance in all wind speeds and directions, to provide more precise tacking results.  A live overlay is also now available in the app of crowdsourced wind & race maps.
