data for wind, wave and current. To download this data on a mobile or satellite connection is very slow and expensive. With the click of a button, the forecasts for all 4 forecast models are quickly and easily displayed to help make informed decisions.

Long-Range Forecasts ​- We have added the ECMWF ensemble forecasts with an incredible long-range 4-week forecast. The ECMWF ensemble is unequivocally the leader in long-range forecasting, and will let you plan your trip well in advance, with better accuracy than traditional climate forecasts.

Reliable -​ The PredictWind router simply works. No failed routes, or issues with the router crossing the land, so you can concentrate on sailing the boat. Check the ​technical report​ for the reliability of the new PredictWind Router.
