Navigate the rugged coastline of the central Inside Passage with the professional authority of the Canadian Hydrographic Service (CHS). Chart 3564 is a specialized "road map" that provides high-resolution, large-scale 1:20,000 plans for essential harbours and technical areas within Johnstone Strait.
While general coastal charts show the broad reaches of the strait, Chart 3564 is specifically designed to guide mariners into specific ports and anchorages where precision is paramount. This chart provides the "ground-truth" data required for safe pilotage:
Large-Scale Plan Resolution: At 1:20,000, this chart offers the extreme detail needed to navigate intricate, hazardous, or shoal-infested waters that smaller-scale charts may generalize.
Strategic Anchorages and Ports: Provides detailed bathymetry and shoreline configuration for the essential stopping points along the Johnstone Strait, ensuring safe transit for commercial shipping, fishing fleets, and recreational boaters.
Essential Navigational Aids: Clearly identifies range lights, buoys, and markers unique to these harbours, allowing for confident maneuvers in tight quarters or low visibility.
Hazard & Seafloor Identification: Explicitly marks submerged rocks, shoals, and seafloor characteristics (such as mud, sand, or rock), providing the reliability needed for secure anchoring.
As the primary reference for intricate locations along one of Canada's busiest waterways, the reliability of Chart 3564 is more vital than ever. Whether you are a professional pilot seeking a heavy-weather refuge or a recreational cruiser exploring the beauty of the North Coast, this official CHS chart delivers the accuracy and detail needed to move from the open strait to a safe berth with total confidence.
