4700 - Belle Isle to Resolution Island | Marine Navigation Map

The Canadian Hydrographic Service (CHS) Chart 4700 is an official, small-scale coastal navigation chart engineered for commercial mariners, deep-sea shipping fleets, and rugged expedition vessels transiting the subarctic waters of Atlantic and Northern Canada. This expansive, authoritative nautical chart provides critical offshore "ground-truth" data for safely navigating the strategic, deep-water corridor connecting the northern tip of Newfoundland and Labrador (Belle Isle) all the way to the southern entrance of the Northwest Passage at the tip of Baffin Island (Resolution Island).

Key Features & Hydrographic Data Included:

• Expansive Offshore Coverage: Delivers wide-area coastal and deep-sea charting spanning from the Strait of Belle Isle, up along the entire rugged Labrador Coast, to the eastern entrance of Hudson Strait.

• Official Bathymetric & Trench Data: Features deep-water soundings, continental shelf contours, and vital seafloor characteristics crucial for safe trans-oceanic passage planning and tracking deep-draft industrial vessels.

• Essential Aids to Navigation: Explicitly details high-visibility lighthouses, offshore buoys, radar stations, and prominent coastal land elevations necessary for safe piloting through unpredictable northern conditions.

• Premium Multi-Light Legibility: Printed with vibrant, high-contrast marine inks specifically engineered to maintain absolute clarity under direct cabin sunlight and dim red-light night-deck setups.

• Legal Vessel Compliance: Fully satisfies international SOLAS (Safety of Life at Sea) carriage regulations and Canada Shipping Act mandates for vessels requiring official hydrographic documentation for northern waters.
