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? Since GPS is available, why not just calculate tacking distances? The SailTimer tacking results solved these problems, 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 polars for your individual sailboat's performance in all wind speeds/directions, to provide more precise tacking results. This is the only product that uses your tacking distances to determine your optimal tack headings.
