5640 - Churchill Harbour Nautical Chart

The Canadian Hydrographic Service (CHS) Chart 5640 is an official, high-precision marine navigation chart engineered for commercial cargo fleets, ocean-going grain vessels, and Arctic operators navigating Canada's primary deep-water Arctic port along the southwestern shore of Hudson Bay in Manitoba.Published at a detailed scale of 1:12,000, this authoritative nautical asset delivers critical "ground-truth" coastal hydrographic data required for safe passage planning, shallow-water maneuvering, and harbour approach routing into Churchill Harbour and the mouth of the Churchill River.

Key Features & Hydrographic Data Included:

• Detailed High-Resolution Harbour Mapping: Delivers continuous, high-definition charting across the port infrastructure, terminal loading berths, turning basins, and river mouth approaches defining Churchill Harbour.

• Official Bathymetric & Seafloor Data: Packed with precise localized depth soundings, undersea contour lines, low-tide marine benchmarks, and subarctic sandbar hazards essential for managing safe draft clearance and secure anchoring during commercial grain and cargo operations.

• Essential Aids to Navigation: Explicitly details official maritime buoys, light stations, daybeacons, and prominent shoreline topography to ensure maximum situational awareness during low-visibility subarctic conditions, fog, or night transits.

• Premium Multi-Light Legibility: Printed with vibrant, high-contrast marine inks specifically engineered to maintain absolute clarity under both direct pilothouse 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 commercial and recreational vessels requiring official hydrographic documentation.
