Choose your polar diagram
In WinGPS 5 Voyager more than 4000 polar diagrams are available. Choose one of these polar diagrams, download the latest GRIB files and plot your desired route. WinGPS 5 Voyager will help you by optimizing your route.
For even better results you can connect an anemometer to your laptop and use the actual wind within the polar diagram. Recording your own polar diagram is also possible with the help of an anemometer. Great when the polar diagram for your ship isn't available!
What is a polar diagram? This is a table with all the optimal sailing speeds of a specific ship at certain courses and wind speeds. While sailing you can immediately check if you reached the optimal speed, or if you need to trim your sail a little bit.
Wind, currents, waves and water heights
Wind, current, waves and water heights all have an influence on your ships' speed. To sail against the current or hit on short high waves is not desirable during a nice sailing trip. By downloading the GRIB files you can see the forecasts for wind, currents, waves and water heights for the next few days. WinGPS 5 Voyager can help you plot an optimized route with the downloaded GRIB files.
