How Does It Work?

When heading on some angle into the wind, sailors face the longstanding seafarer's dilemma of how close to the wind to sail.
Do you pinch close to the wind to shorten your distance, even with a loss in speed? 
Or head off the wind to pick up speed (but increasing distance to travel)?

You might think that modern electronics would have provided a solution for this long-standing navigation problem. 
But even if you spend $1000 or more on a GPS or chartplotter from any manufacturer,
as soon as you start tacking upwind the ETA may blank out as if you are off-course.

Fortunately, The Sailing GPS provides a solution.

Whether you are racing, long-distance cruising or pond sailing on a Sunday afternoon,
you can see the optimal tacking route at a glance.

Just enter the directions of the wind and your destination with two buttons and the optimal tacking angles are displayed.
Enter your boat length, distance to destination and wind speed, and we can now calculate your Tacking Time to Destination (tm)
as well as the distances on each tacking leg.

Even experienced sailors have a difficult time picking the optimal sailing angle, especially when you are not heading directly upwind.
The Sailing GPS provides a simple solution for this longstanding problem.
