Specs

• View Grib file weather forecasts for:
      Wind (10 meter)
      Current, including NOAA RTOFS Gulf Stream
      Pressure (Mean Sea Level)
      500 mb height
      Sea temperature
      Rain (accumulated precipitation)
      Wave height
      Wave height and direction
      Wave period
• NOAA Gulf of Maine Tidal Current (GOMOFS). High res 0.6 NM grid, hourly forecasts out to 72 hours (3 days). The SailFast server converts the GOMOFS NetCDF file format into useable compressed binary for minimum size downloads. (New Version 10.0)
• Easy Grib viewing. Accepts multiple Grib files. No pre-processing required. View both historic and forecast grib data.
• Directly compare multiple grib models on-screen, such as NOAA GFS and Navy NAVGEM and COAMPS
• Display a patchwork of mesoscale models and perform optimum routing. You are not restricted to using a single wind Grib file for routing.
• Tool to create Saildocs Grib file requests. With an internet connection free Grib files may be downloaded directly to your PC without any intermediate email steps. Compatible with Sat phone data link.
• Active and Saved vessel track display with point by point log of user selected weather and sailing performance data.
• Use as a local data repeater to view GPS and instrument data, plus ...
      % Speed (Actual boat speed compared to polars)
      Computed actual current set & drift. Great for the Gulf Stream! See our App Note.
• Built-in global base map. Optional city name display
• Sixteen sample boat polars: (8 Added Version 10.3) Archambault A35, Aerodyne38, Aerodyne43, Baltic44_(Asym&Sym), Beneteau First 36.7, Beneteau First 40.7, Beneteau Oceanis 351/352 (WK), Catalina 22, Catalina 36, C&C34-36 XL (WK), C&C 402 (DK), Farr 40, J109, Quest 33, Sabre 362, Sabre 38-2
• Customize an existing polar or enter your own.
• Isochron optimum weather routing with time steps from 0.25 to 6 hours.
• 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.).
• Print images of SailFast chart and Optimum Route Table.
• What-If Analysis
      User settable sailing boundaries
      Alternative course analysis
      Manual override of Grib wind or current (temporary, time phased or permanent)
      Add/subtract to Grib wind speed and/or direction
      Avoid extreme wind
      Avoid extreme significant wave height
      Run on-engine when wind is light
• Waypoint Laylines (New Version 10.0)
      Port and Starboard layline display (requires NMEA wind sensor, boat speed amd heading)
      Layline range over previous 5 and 10 minutes.
      Time and distance estimate
      Target boat speed, bearing, apparent and true wind angles
      Audible notifications on layline approach
• Range / bearing and Line Of Position drawing tools. (New Version 10.0)
• Interface to NMEA 0183 GPS and Wind Instrument data (not required for basic optimum routing operation and Grib viewing). Display or log all NMEA data.
