SailFast™ is a PC-based navigation program used to predict optimum routes for offshore racing. Weather information is imported directly from GRIB forecasts of wind and current. When used in the biannual Marblehead to Halifax Ocean race detailed Gulf of Maine tidal currents are already included.

Taking into account vessel speed characteristics, predicted wind and current, SailFast™ determines the fastest course from start to finish, or between any 2 waypoints. “Isochron” methods are used to find a globally optimized route. A typical isochron solution from start to finish takes about 3-5 minutes to compute.

SailFast ™ predicts vessel speed using standard polar diagram information. A scalable generic polar diagram is also included which may be used when the skipper does not have polars for his boat. Various “what-if” capabilities are included to allow the navigator to explore course and weather alternatives. SailFast is a powerful tool to assist with the tactical and strategic decisions that win or lose races.
