5641 - Arviat & Approaches Nautical Chart

The Canadian Hydrographic Service (CHS) Chart 5641 is an official, high-precision marine navigation chart engineered for commercial cargo fleets, community resupply barges, and subarctic marine operators navigating the western shores of Hudson Bay in Nunavut’s Kivalliq Region. Published at a detailed scale, this authoritative nautical asset delivers critical "ground-truth" hydrographic data required for safe passage planning, shallow-water maneuvering, and harbour approach routing into Arviat (Eskimo Point) and its surrounding coastal approaches.

Key Features & Hydrographic Data Included:

• Detailed High-Resolution Approach Mapping: Delivers continuous, high-definition charting across the coastal shoals, sheltered anchorages, and landing channels defining the harbour approaches at Arviat.

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