Ah the lonely about dialog. You can see the version, the copyright, and how to contact us for help (tapping here opens a mail message so you can contact us any time. Usually we’re here, if not you’ll hear from us soon). You can also go to this website (hi!), or the MacSailing forum which is a great place for information about sailing with a Mac, an iPod, an iPhone, an iPad, or whatever else a sailing Machead would want.
Oh, and there’s the nowadays obligatory disclaimer that says this is just a prediction, don’t rely on it as your sole source for navigation, etc. etc. etc. Basically, be smart out there and keep a weather eye out*.
