SailSmart

sail watch with two functions.

Countdown timer, with smart adjustment function and Live GPS info, with current heading and speed.
Slide-up menus allows navigation between the two functions.

Furthermore the watch makes some assumptions, which can be used when sailing close-hauled (still experimental).
The watch will discover when ever you tack, and store last course. This way you can compare the leg to previous legs. The watch indicates when it detects a tack (by showing "CW" or "CCW" in the right side of the screen). After the tack it will indicate which tack it assumes you are on.
When sailing along on a tack, the heading will be evaluated. Colors indicate if the wind veers aft or haul forwards.
