Explore the deep-water secrets of the British Columbia Central Coast with the professional authority of the Canadian Hydrographic Service (CHS). Chart 3931 is a specialized large-scale navigational tool, providing the granular detail required to safely traverse the majestic fjord systems of Smith Inlet, Boswell Inlet, and the tide-sensitive Draney Inlet.
The region north of Queen Charlotte Sound is a landscape of extreme relief and powerful tides. CHS Chart 3931 provides the "ground-truth" data required for safe pilotage in these technical zones:
Draney Narrows & Tidal Detail: Features the high-resolution mapping necessary to navigate the high-velocity currents of the Draney Narrows, where timing is critical for safe passage.
Fjord System Comprehensive Coverage: Detailed bathymetry for the full extent of Smith Inlet and Boswell Inlet, identifying submerged hazards and steep-walled shoreline characteristics.
Safe Anchorage & Seafloor Intelligence: Shows precise water depths and the nature of the sea bottom (mud, rock, or sand), vital for securing a safe anchorage in the deep basins of Takush Harbour or Wycliffe Inlet.
Hazard & Landmark Identification: Explicitly marks drying reefs, kelp forests, and navigational aids, providing essential situational awareness for fishing vessels, eco-tourism operators, and wilderness cruisers.
As the primary navigational resource for vessels exploring the inlets branching off Smith Sound, the reliability of Chart 3931 is paramount. Specifically designed to meet the rigorous requirements of marine navigation, this official CHS chart delivers the accuracy and detail needed to explore the BC wilderness with total confidence.
