Navigate the scenic and technical waters of Vancouver Island’s interior with the professional authority of the Canadian Hydrographic Service (CHS). Chart 3668 is the definitive 1:40,000 scale "road map" for mariners, providing the comprehensive coverage required for safe transit through the Alberni Inlet, the longest fjord on the island's west coast.
As the primary route for international cargo ships and heavy recreational traffic, the Alberni Inlet requires precise situational awareness. CHS Chart 3668 provides the "ground-truth" data required for safe pilotage:
Strategic Transit Coverage: Offers the necessary resolution for the 40km transit from the mouth of the inlet to the head of the fjord at Port Alberni.
Technical Narrows & Bays: Provides high-detail bathymetry for Stamp Narrows, San Mateo Bay, and the entrance to Uchucklesit Inlet, essential for avoiding submerged hazards in these confined waters.
Port Alberni Approaches: Includes the latest configurations for the commercial docks and recreational marinas in Port Alberni, the vital industrial heart of the region.
Essential Navigational Data: Explicitly marks the nature of the sea bottom, elevations, and characteristics of the rugged shoreline, as well as the latest aids to navigation for safe night-time or low-visibility transit.
With the convergence of commercial shipping, heavy fishing activity, and world-class eco-tourism, the reliability of Chart 3668 is paramount. Specifically designed to meet the rigorous requirements of marine navigation, this official CHS chart delivers the accuracy and detail needed to navigate from the open sound to the inland port with total confidence.
