A new version of SailTimer is available as an easy download in iTunes. The iPhone has a GPS in it. SailTimer has a LARGE display of speed in knots. But even when there is no GPS (on an iPod) or no internet connection (for Google Maps), you can get some very helpful tacking information.
Just enter the angles of the wind and your destination, and presto: you get the optimal tacking angles. Add the distance to the destination and you can tell your overall tacking distance. And if you add your boat length, you can even tell how long it is going to take to get there. Even on an iPod, with no GPS.
As you can see from the following screenshots, you get navigation capabilities designed especially for sailors. Standard GPS chartplotters do not account for the obvious fact that sailboats zig-zag across the wind. How can they calculate your correct ETA if they don´t know how far you are tacking? Unlike the cost of GPS chartplotters, this is an inexpensive download for a device that you can carry around in your pocket.
It is pretty amazing that in all of the centuries of seafaring traditions, there has been no easy way to get this information until now. (www.indepthnavigation.com)
