How do I use wind indexed ratings?

Last edited 1st June 2018 by Jon

Note that the wind indexed options are not enabled by default in Sailwave because they are little used – use the User Interface window to enable them on a per series basis.

Edit a scoring system and enable wind indexed ratings on the RatingSystem tab. Enter a comma-separated list of wind strengths that will be used for the corresponding wind indexed ratings. Using the USSA PN scheme as an example, the list would look something like this:-

0-1, 2-3, 4, 5-8

Note that the spaces are ignored and the list could also look like this:-


The strings (“0-1” etc) are completely arbitrary and you could have alternatively written:-

None, Gentle, Medium, Strong

When you sail a race you log the wind strength in a race start – a drop-down list allowing you to select one of the above values.

Each competitor should have a default rating defined and also a comma-separated list of ratings to use for each of the wind strengths defined above; for example:-


Note that a null value in the list is interpreted as use the default value. For example, if the default value was 101 the list of wind index ratings could have been written:-


If the default value was 100 it could have been written:-


When you score the series with wind indexing enabled Sailwave looks at the wind strength logged in a race start and then choose the appropriate rating for the competitor from their list of wind indexed ratings; from which it can calculate an appropriate corrected time. If a race is not logged with a wind strength the default value is used.
