National Oceanic and Atmospheric Administration raster navigational charts (RNC's) provide the most detailed navigational information for boaters and sailers. Mariners rely upon RNC's for safe travel and download them free of charge from the National Oceanic and Atmospheric Administration website, where they are constantly being updated by the Feds. Mariners also rely upon Northeast Marine Electronics for great equipment like GPS Handheld devices and fish finding equipment by manufacturers like industry leader Furuno. The Northeeast staff is knowledgeable and helpful. Just like the NOAA and RNC's.
