The Gateway to the Remote: 3550 - Approaches to Seymour & Belize Inlets

Unlock the hidden fjords of the BC mainland with the professional authority of the Canadian Hydrographic Service (CHS). Chart 3550 is the indispensable 1:40,000 scale "road map" for mariners, providing the precise data required to navigate the technical approaches to Seymour Inlet, Belize Inlet, and the legendary Nakwakto Rapids.

Critical Precision for High-Consequence Navigation

The approach to Seymour and Belize Inlets is widely considered one of the most challenging segments of the Inside Passage. CHS Chart 3550 provides the "ground-truth" data required for safe passage through these high-flow waters:

• The Nakwakto Threshold: Features the critical detail necessary for approaching the Nakwakto Rapids, famous for tidal currents that can exceed 14 knots. This chart is vital for timing your transit with slack water near Turret Rock.

• Intricate Channel Mapping: Provides high-resolution bathymetry for Slingsby Channel and Schooner Channel, the two primary arteries leading from Queen Charlotte Sound into the secluded inlet systems.

• Essential Shoreline & Hazard Data: Explicitly marks the dense cluster of rocks, islands, and reefs surrounding Brahman Island and Allison Harbour, where situational awareness is paramount for avoiding submerged dangers.

• Gateway to the Inlets: Provides the necessary navigational leads to enter the 200+ miles of spectacular fjords including Nugent Sound and Alison Sound, where vertical rock walls meet deep-water basins.

The Professional Standard for Remote Coastal Safety

As the primary reference for one of the least visited and most rugged areas of the British Columbia coast, the reliability of Chart 3550 is vital. Whether you are a professional captain timing a technical transit or a wilderness explorer seeking the isolation of the mainland fjords, this official CHS chart delivers the accuracy and detail needed to navigate with total confidence.
