The PredictWind weather service is popular with offshore sailors, and with a paid PredictWind subscription weather forecasts and routing can be requested via email including access via Sailmail.   Our Airmail software version 3.5.054 onward (from January 2020) streamlines access, but any older version can also provide simple access to PredictWind forecasts.   Any method of connection can be used: SSB radio, Iridium or Inmarsat handsets or terminals including the Iridium GO.
