Navigate the rugged heart of the British Columbia Central Coast with the professional authority of the Canadian Hydrographic Service (CHS). Chart 3910 is a specialized "multi-plan" navigational tool, providing the high-resolution detail required to safely traverse the transition from the open Pacific waters of Milbanke Sound into the sheltered, complex channels of the Inside Passage.
The area surrounding Milbanke Sound is a high-energy maritime environment characterized by narrow gaps and hidden reefs. CHS Chart 3910 provides the "ground-truth" data required for safe pilotage in these technical zones:
Multi-Plan Resolution: Unlike broad coastal maps, 3910 features large-scale, high-detail inserts for critical refuges and passages, including St. John Harbour, Higgins Passage, and segments of Beauchemin Channel.
Inside Passage Safety: Offers the granular resolution necessary to identify safe leads through the rocky fringes of Price Island and Aristazabal Island.
Anchorages & Seafloor Intelligence: Shows precise water depths and the nature of the sea bottom (rock, sand, or mud), vital for selecting secure mooring in the deep, tide-swept inlets of the Central Coast.
Hazard & Landmark Identification: Explicitly marks drying reefs, kelp forests, and navigational aids, providing essential situational awareness for commercial fishing fleets, tugs, and wilderness cruisers.
As a primary resource for mariners transiting the "Outside Route" or seeking shelter from the swells of Milbanke Sound, the reliability of Chart 3910 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.
