RayTech RNS Weather Services keep you informed as to the latest conditions at home and offshore. Using the same powerful GRIB (Graphics in Binary) forecast models produced by the US National Weather Service, RayTech RNS 6.1's advanced weather engine can show you complex metrological events right on your navigation charts.

RayTech RNS' weather engine can show you detailed weather data like wind speed and direction, surface pressure, surface temperature, precipitation and more. Forecast data can be layered on top of any of RayTech's navigational charts giving you the ability to see how the weather will affect you where you are now, and into the future.

Best of all, RayTech RNS 6.1 renders this animation in bold, easy to read colors and with full animation. This enables the navigator to actually "see" the predicted passage of fronts, cells and other weather phenomena, right on top of the navigation plot.

For the offshore sailor, the powerful GRIB weather engine is used in tandem with RayTech RNS 6.1's standard Weather Routing feature. Using the detailed forecast data in the GRIB model, a worldwide database of ocean currents, and your plotted track plan RayTech calculates the optimal courses to steer to maximize efficiency under sail.
