Whether receiving wireless data from the SailTimer Wind Vane or manually entering wind information, the SailTimer app calculates your optimal tacks andTTD (Tacking Time to Destination). Another amazing advancement with mobile devices.
The Estimated Time of Arrival (ETA) on a standard GPS chartplotter does not take tacking distances into account. But if it doesn’t know how far you are going to travel, how can it calculate your arrival time? The SailTimer app solves this problem. It calculates your exact tacking distances, will continuously update your optimal tacks and TTD as the wind changes.
