Regatta Compass

The app provides the crew with tactical information, such as
- course (COG),
- tack advantage,
- speed over ground (SOG) and
speed on target (SOT).

For the pre start phase, it provides a
- countdown timer,
- distance to starting line and
- predicted line excess at start.

While racing the app provides the crew with the following: Basic information are the current 'course over ground' (COG) and 'speed over ground' (SOG).
The 'tack advantage', which is derived from the direction of the up- and downwind legs, enables you to optimally utilize wind shifts in gusts. If the tack advantage increases, you are good. If it is negative, you should consider to tack (or jibe). Used properly, the tack advantage let's you sail more direct to the target, which is simply faster. This is indicated by the 'speed on target' (SOT) and more important than only the speed over ground.

During the pre start phase is supports the crew with countdown timer, distance to the starting line and assumed line excess at start.

The countdown beeps every minute. Use “trim” to set the running countdown to the closer minute in order to adjust it to the starting signals. To not cross the starting line before start the application shows the distance to the line. To cross the line with full speed at exactly the aimed starting time, the application shows the assumed starting line excess based on the time to go, the current speed and course. Slow down in case of positive line excess and speed up otherwise to optimally start the race.

In order to calculate the tactical information, the upwind course direction, the tack angle of the boat and the geo location of the starting line buoy must be set up before racing („Settings dialog“).
