As per the recent RORC Amendment Number Two to the Annual Notice of Race, 3.5 Rule 41(c) is replaced by: ‘’A boat shall not receive help from any outside source, except (c) help in the form of information which is freely available to all boats, which shall include navigational, weather, tide or current information from any source which is available to all boats whether or not by payment of a fee or subscription, but shall not include information gathered or the subject of interpretation by, or any advice received from, any person not on board the boat and which is specific to the boat and her situation. By way of an example and interpretation, downloading charts, weather and/or tidal GRIB files from subscription services, or having such information passed to the boat in its pure form, is permitted. The use by competitors of publicly available cloudbased weather routing services is permitted. Receiving messages or information which is the result of human interpretation as it applies to the boat is not permitted’’

Polars describe your boat speed and wind angle in any given weather situation. Setting the polars in your PredictWind account is essential for an accurate weather route. It is vital you set the polars in your account before using the weather routing and departure planning tool on any of the PredictWind platforms.

For detailed instructions on setting up boat polars, see the help article:How to Set Up Boat Polars - All Platforms

With PredictWind Weather Routing, you can set your Wave Polar not only to define the performance of your boat in various wave conditions but also to view the Roll, Vertical accelerations and Slamming Incidence that your boat will experience through the route. For detailed instructions on Wave Polars, please take a look at the help article:Weather Routing using Wave Polars
