All maps are available for download. Weekly updates to the RNCs are done on a 'best efforts' basis. The timing of their availability is not guaranteed. Since complete ENC coverage is available in all U.S. waters, vessels required to use ECDIS may NOT navigate with NOAA RNCs. RNCs are approved for use by IMO ECDIS mandated vessels only if adequate ENC data is not available. NOAA RNCs DO NOT meet USCG chart carriage requirements for commercial vessels. The NOAA RNC are intended for navigational use. NOAA RNC are not intended to meet federal chart carriage regulations published in the Code of Federal Regulations. NOAA makes no representations that the RNC Tile Service or the RNC Tiles provided thereunder meet federal chart carriage regulations.
