There are two software options – Grand Prix, which is operated on a PC, and Seatrack Smart, which is operated on an Android tablet.
Besides their ranges of navigational functions, both options have tactical and performance features that give an invaluable competitive edge, while Grand Prix also has an important safety at sea role in its Man Overboard and AIS functions.

Seatrack Grand Prix
The Polar Management, Sail Chart and Target Speeds & Analysis functions have been developed to provide vital information towards maximizing performance in all conditions and at all points of sailing. The value of their output, however, depends upon the accuracy of the yacht’s instruments and the calculation of its polars. In this context, the importance of instrument calibration cannot be over-emphasised. This has been addressed by Grand Prix’s Instrument Calibration function, which offers unique facilities to eradicate the inherent errors in most instruments' wind data calculations.
Grand Prix has two critically important safety at sea functions – Man Overboard, which gives the precise predicted range and bearing to the man or woman in the water, taking into account tide, current and wind effect; and AIS, which shows the course and speed of all large vessels within VHF range, giving a minute-to-minute assessment of collision threat and thus countering the risk of being run down.
Perhaps most significantly, Seatrack Smart includes Chart Plotting with a tactical overlay, Start Line showing time and distance to the line with a countdown timer and a Tactics screen showing This Leg and Next Leg data. Note also that performance maximization is facilitated via Polar Management and Target Speeds & Angles.
