4363 - Cape Smoky to St. Paul Island | Northern Cape Breton Marine Map

Navigate the powerful waters of the Cabot Strait and the rugged northern tip of Nova Scotia with the CHS Nautical Chart 4363: Cape Smoky to St. Paul Island. This official publication by the Canadian Hydrographic Service (CHS) is a vital resource for mariners transiting the northeastern coast of Cape Breton Island.

Covering the dramatic coastline from the towering cliffs of Cape Smoky to the legendary "Graveyard of the Gulf," St. Paul Island, this chart provides the essential bathymetric data needed for safe passage through these deep-water reaches. This region is a major corridor for commercial shipping entering the Gulf of St. Lawrence and is frequented by fishing vessels and intrepid coastal cruisers. Due to the significant depths and exposed nature of the Atlantic coast here, Chart 4363 offers critical information on underwater topography, shoreline hazards, and navigational aids.
