Main Features Include: * NOAA Raster Nautical Charts (RNC) * NOAA Weather Map Overlays NOAA Weather Data Includes: * NEXRAD HD Radar * Sea Surface Temperature * Significant Wave Height * Wind Speed & Direction * Air Temperature * 12-Hour Rain Probability -- IMPORTANT -- ** Do NOT use for navigation ** NOAA RNC charts are full-color, geo-referenced, digital images of NOAA paper nautical charts. RNCs are approved for use by IMO ECDIS mandated vessels only if adequate ENC data is not available. Since complete ENC coverage is available in all U.S. waters, vessels required to use ECDIS may not navigate with NOAA RNCs. NOAA RNCs do NOT meet USCG chart carriage requirements for commercial vessels. -- If you have any questions, please email me at [email protected] Enjoy!
