The Canadian Hydrographic Service (CHS) Chart 5800 is an official, high-precision general navigation chart engineered for commercial shipping fleets, industrial supply barges, and Arctic expedition vessels traversing Baie James (James Bay). Published at a general overview scale of 1:500,000, this master hydrographic chart provides critical broad-scale coastal and offshore data required for main-route passage planning, deep-water transit, and long-distance navigation between Hudson Bay and the major coastal communities of Nunavik, Quebec, and Northern Ontario.
Comprehensive Regional Coverage: Delivers a complete overview of James Bay, stretching from its northern confluence with Hudson Bay south to Akimiski Island, Hannah Bay, and coastal river entrances.
Official Bathymetric & Seafloor Data: Features reliable offshore bathymetry, localized depth soundings, major undersea ridges, and subarctic shoal hazards essential for safe blue-water passage planning and draft management.
Essential Aids to Navigation: Highlights official major light stations, marine beacons, offshore buoy networks, and prominent coastal landforms for reliable visual positioning and long-range routing.
Premium Multi-Light Legibility: Printed with high-contrast marine inks designed to maintain absolute clarity under direct bridge sunlight as well as low-light red-deck conditions.
Legal Vessel Compliance: Fully satisfies international SOLAS (Safety of Life at Sea) carriage requirements and Canada Shipping Act mandates for commercial and industrial operators needing official regional chart coverage.
