Board » Technical Support » 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.

So which ones should plugin to Sailplanner?
You can simply download the polar from the info tab in the client and load it into Sailplanner. and voila!

Sailonline’s 15th Birthday Balloon Race
Sailonline offers a huge variety of boats to sail in. One of the more unusual ones has got to be SOL's Balloon, which was polarized by past SOLmaster 76Trombones. Notably, the SOL Balloon will actually ‘sail’ in other directions other than straight downwind, although it will not 'sail' over land or beyond a 'beam reach'. Like in 2013 and 2018, we will be taking the Balloon across the Atlantic from St. John's and 'land' it in the sea off the Cliffs of Moher.
