2016-08-26 03:37:55 - Notification of updated polars
Howdy. I have a simple request to the SRC.

It seems that sometimes the polars for a particular boat are updated, but it also seems that there is not a name change to the polar file when this happens. It also seems that there is not necessarily a public notification that this has happened.

A number of SOLers, myself included, make modifications to the polar, for as Brainaid's site says, 'the polar data might not be optimal, work in progress'.

Hence, it is not practical to re-download the polar from brainaid with every new race, as this could involve a lot of extra work editing the polar again, which might not even be needed if the polar file has not been changed.

Could we just, from now on, add a tag to the file name (eg _ver2, 3, etc). That way we can easily identify when we are using the current polar and there would be no need for public notifications of the change.

Many thanks, and of course, thanks also for all your hard work bringing us the great racing calendar!

As far as I'm aware, no polars have been updated after their first use.

Thanks Huib,
that's good to know. I remember the Volvo polar was updated and given an name change. I should have ignored the comment in the forum to 'make sure I download the latest polars from Brainaid' then. :) I thought it would be unlikely that changes would be made without notification, but thanks for the confirmation anyway. cheers

TuziTekwini TIMED Race 2026

Sailonline is delighted to have been invited again to partner with the King Shaka Yacht Club (KSYC) of South Africa to bring a virtual version of the Tuzi Tekwini Ocean Raceto our online community.
The Tuzi Tekwini Ocean Race is a near 90 nautical mile race down the east coast of South Africa from the port of Richards Bay to the port of Durban. Achievable in a single day and seen by some as an easy mile-builder, the course is more tactical than some think and should not be underestimated. This iconic race promises to be an unforgettable experience for yachting enthusiasts.
Our online version of the race will be a TIMEDrace so you may RE-REGISTER HEREto try again after finishing a run. You will have two weeks to test your skill and decision making after the race opens.
