Our waterproof charts are an excellent tool for recreational sailors to navigate with. Using nautical data from the National Oceanic and Atmospheric Administration (NOAA) and National Geospatial-Intelligence Agency (NGA) these charts cover some of the most popular inlets, waterways, and commonly sailed routes in U.S. waters and in the Caribbean. They can be used a substitute to standard nautical charts for small recreation boats only. These charts are laminated and will be protected from any exposure to water.
