iRegatta 3.05.0 works with iPolar
KND-SailingPerformance (www.sailingperformance.com/) has developed an app to predict polars for Crusing Yachts.
iRegatta will be able to import these polars directly from the iPolar App, starting from version 3.05.0 of iRegatta. The update has been submitted to Apple for approval, so it should be available within 2 weeks.
(iPolar is an "iOS only" app, so this feature will of cause only be available in the iOS version of iRegatta).
