We give you a three step navigation explanation with diagrams - and you are ready to go to plot your favorite cruising route, avoiding rough seas and high winds, or try being a Volvo Ocean Race navigator
What can take hours to do manually happens with the click of a button on PredictWind.
Simply place your start and finish points on the map, and select the start time for your passage.
Then, using the selected forecast model, the tool will work out the best path to your destination. Any passage spans across changing weather patterns, swell conditions and currents, and the tool quickly calculates the optimal route for you.
The boat polars allow you to tailor the routing to your specific boat, then you can either choose a route that is optimised for speed or comfort.
Standard and Professional accounts include land avoidance which can be very useful when sailing coastal passages.
Weather Routing in the Professional account also includes ocean and tidal currents which can have a significant effect on routing. You can also receive weather routes via email by sending your current and destination location to PredictWind’s server. This option is great for offshore data use as it is the most economical way (even compared to grib files) to receive routing information.
Weather Routing is a great tool that every sailor should find simple to use and effective in helping find the most suitable route for their next voyage.
