DataHub Automatic Polar Generation

To take advantage of this great feature in the Offshore App, first, you need the following:

  1. A DataHub connected to your NMEA 2000 instrumentation system outputting Apparent Wind Speed, Apparent Wind Angle, Speed over Ground and Course over Ground.

  2. GPS Tracking must be enabled on your DataHub. AI Polar data is uploaded with GPS tracking position reports being sent.

  3. Then you need to enable AI Polars in the DataHub.

  4. Set up your boat's base polar and select to use AI Polars in the Forecast Website > Sail Routing > Routing Preferences.

To learn how to set up and enable AI Polars in your PredictWind Forecast account, please review AI Polars - DataHub Automatic Polar Generation.

Setting Up DataHub Polars in the Offshore App

When you have set your Sail Routing Preferences in the Forecast Website to use DataHub polars, the Offshore App will automatically sync these settings the next time it is opened with a high-speed Internet connection, e.g. Cellular, Starlink or high-speed Wi-Fi.

Important Note - Iridium GO! and GO exec: If you're offshore already and want to run a weather route in the Offshore App using the Iridium GO! or GO exec as the Download Method, you must manually change the Boat Polar.

Syncing DataHub Polars with the Offshore App

To check if the Offshore App is using DataHub Polars, or to change it:

  1. Open the Offshore App.

  2. Tap Download.

  3. Tap Weather Routing Preferences.

  4. Tap Route Settings > Boat Polar.

  5. At the top of the screen, check that Boat Polar > Boat Type > DataHub is selected. Then tap < Back and < Weather Routing Preferences in the top left.

  6. At the bottom of the screen, tap Continue to Download. This will then use your DataHub AI polars for weather routing.
