SailFast™ is a PC-based navigation program used to predict optimum routes for offshore racing
and cruising. Weather information is imported directly from Grib forecasts of
wind, current and sea level pressure etc. Built-in Gulf of Maine tidal currents are
Taking into account
vessel speed characteristics and 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.
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. Polars for a number of popular boats are also built-in. 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.
