Chart 3902 is the definitive small-scale "road map" for mariners, providing the wide-area situational awareness required to safely cross Hecate Strait. This chart is a critical asset for vessels transiting between Prince Rupert, Kitimat, and the shores of Haida Gwaii.

Critical Intelligence for a Dynamic Marine Environment

Hecate Strait is world-renowned for its rapid weather changes and unique bathymetry, featuring extreme depth transitions and the expansive, shallow Dogfish Banks. CHS Chart 3902 provides the "ground-truth" data required for safe passage:

• Comprehensive Regional Coverage: Provides a continuous view of the strait, linking the mainland fjords with the eastern shores of Graham and Moresby Islands.

• Bathymetric Hazards: Detailed mapping of the Dogfish Banks and the steep continental shelf drops, identifying areas where sea conditions can become hazardous during opposing tides and winds.

• Strategic Transit Planning: The ideal tool for calculating offshore courses, identifying major light stations (such as Bonilla Island or Rose Spit), and planning landfalls in Skidegate Inlet or Browne Passage.

• Essential Navigational Aids: Clearly marks the locations of weather buoys, major lights, and undersea features that define the transit routes for the Inside Passage and commercial shipping lanes.

The Professional Standard for North Coast Safety

As the primary navigational resource for commercial freighters, fishing fleets, and long-range cruisers, the reliability of Chart 3902 is vital. Specifically designed to meet the rigorous requirements of marine navigation, this official CHS chart delivers the accuracy and scale needed to traverse the Hecate Strait with total confidence.
