The Canadian Hydrographic Service (CHS) Chart 5533 is an official, high-precision marine navigation chart engineered for commercial cargo fleets, industrial resupply vessels, and Arctic operators navigating the northwestern reaches of Hudson Bay along the Kivalliq region of Nunavut. Published at a comprehensive passage scale, this authoritative nautical asset provides critical "ground-truth" coastal data required for safe passage planning, shallow-water maneuvering, and coastal routing through Roes Welcome Sound—stretching from the approaches of Chesterfield Inlet northward to Cape Munn at the southern tip of Southampton Island.
Comprehensive High-Latitude Sound Mapping: Delivers continuous, high-definition charting across the strategic, tide-driven channel of Roes Welcome Sound connecting Hudson Bay with Repulse Bay and Wager Bay.
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.
