Thanks for your question. Actually, there is varying support for different amounts of polar plot data on the different platforms that SailTimer runs on.
For example, you can define polar plots with MacENC for your own boat's unique performance. At present there is a generic model of polar plots, hullspeed and wind speed in the current version of the SailTimer app for iPhone and iPod.
If I understand your question about gybing angles correctly, the polar plots with all of these approaches do inherently take into account both tacking and gybing angles.
It would be impractical to try to keep a database of polar plot data for every different model of boat. But we have an even better approach with the new dedicated handheld called The Sailing GPS (patent pending)... Even two different boats that are the same model could perform very differently, if one is covered in barnacles, weighed down with cruising gear, and has bagged-out sails. So The Sailing GPS actually learns the unique polar plots for your individual boat. That is the ultimate way to get the most precise projections possible for speeds and arrival times.
