Nautical Charts
It is a requirement that all vessels that transit the St. Lawrence Seaway Great Lakes have the latest edition of either U.S. or Canadian charts. (British Admiralty charts are not acceptable.)
It is also required that vessels have the latest editions of publications such as: U.S. Coast Pilot, U.S. Light List, Canadian Sailing Directions, Canadian Radio Aids to Marine Navigation, Canadian List of Lights, and all of the latest Notices to Mariners.
Pleasure craft operators should have up-to-date nautical charts for the waters they are sailing.
Nautical charts as well as catalogs of charts and nautical publications may be ordered through the following agencies:
