The Canadian Hydrographic Service (CHS) Chart 5860 is an official, high-precision marine navigation chart engineered for commercial barges, freight operators, and subarctic mariners navigating the extreme southern waters of James Bay in Northern Ontario. Published at a detailed approach scale, this authoritative nautical asset provides critical "ground-truth" coastal hydrographic data required for safe passage planning, shallow-water maneuvering, and estuarine transit into the Moose River leading toward Moosonee and Moose Factory.
Detailed High-Resolution Approach Mapping: Delivers continuous, high-definition charting across the shallow estuarine channels, shifting sandbars, and mudflats defining the approach into the Moose River mouth from James Bay.
Official Bathymetric & Seafloor Data: Packed with precise localized depth soundings, undersea contour lines, low-tide marine benchmarks, and tidal flats critical for managing safe draft clearance in variable estuarine waters.
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.
