The Canadian Hydrographic Service (CHS) Chart 5801 is an official, high-precision marine navigation chart engineered for commercial cargo vessels, regional supply barges, and subarctic marine operators navigating the eastern shores of James Bay along the coast of Eeyou Istchee / Nunavik, Quebec. Published at a detailed passage scale, this authoritative nautical asset provides critical "ground-truth" coastal hydrographic data required for safe passage planning, shallow-water maneuvering, and coastal routing from Long Island (at the junction of Hudson Bay and James Bay) south along the eastern archipelagos toward Fort George (Chisasibi).
Detailed High-Resolution Coastal Mapping: Delivers continuous, high-definition charting across the islet-dense waters, coastal channels, and sheltered sound routes from Long Island down to the mouth of the La Grande River near Chisasibi.
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 in variable coastal waters.
Essential Aids to Navigation: Explicitly details official maritime buoys, coastal 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.
