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. Optionally use the built-in Gulf of Maine tidal currents.
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 set up and 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.
For the cruiser Sailfast is invaluable for voyage planning and safety. Routing options include avoidance of extreme winds and wave height, and sailing reduced boat speed at night.

Optimum Route Table: View detailed data for each segment of an optimum route including lat lon, apparent and true wind, heading, boat speed, SOG, COG, and current. It is now easier to follow the suggested routing, plan sail changes and judge actual vs. simulated performance. The table and chart are interactive and synchronized. Highlight a table route segment and the chart will show vessel position and related weather forecast values (wind, current etc.). (New Version 9)>
