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.

Camel or Balloon - Khartoum to N'Djamena


As there is a lull in the calendar, your PRO has decided to risk an experiment – a balloon race over land, using a workaround to eliminate the recognition of water/land transitions. If it fails, the server may crash, and we abandon PDQ, hopefully after leg 7 of the ABS race to Suez has been decided, and before the start of the 1st OCC of Q4. Camel or Balloon – c 1000 nm from a field on the north bank of the Blue Nile at Khartoum to a field on the north bank of the Chari River at N'Djamena!
