2009-12-01 19:04:34 - VO 70 Polars Question for Jakob
The V0 70 polars provided for the Miami to Kingston Race appear to contain some anomalous data points, resulting in odd inflections in the polar curves.

The Performance Polar (for experts) table presented under Helpful Links indicates greater boatspeeds at twa 36 than twa 39 for tws 10 and tws 14 - this seems highly unusual and may be causing the double inflections in the polar curves. Also note that the file is labeled VO70_leg2, instead of the _leg4 file which was used more recently.

So is this the correct performance model which will be used for this race, or will the more updated VO70_leg4 model be used instead?

Also, a listing of the available polar data files and a link to them, along with a clear indication of which file is being applied for each race, would be a handy reference for everybody.

Thanks,
Rhino

Hi
The polar shown in the client is the polar that will be used in the race. We have several VO70 polars that we alternate :-) Some may have the behavior you refer to. Happy sailing.

Lake Vättern PYOC 2026


Back in 2013, longstanding SOLer Musigny and his friend xthyra invited us for a three race tour of beautiful Lake Vättern in the heart of southern Sweden. After many years, we return there for a quick sprint from a start in front of the village of Brandstorp, either way around Visingso island in the middle of the lake, but PORT HAND ROUND a buoy off the Granna piers on the eastern shore and back, once again avoiding Visingso as best you can. At least 20nm in trusty Scandinavian 11m One Designs; good luck!
