The Canadian Hydrographic Service (CHS) Chart 4820 is an official, high-precision marine navigation chart designed for commercial shipping fleets, passenger ferries, and regional fishing operators traveling the island-studded northern coast of Newfoundland. This authoritative nautical asset provides critical "ground-truth" data for safely transiting and maneuvering through the wide, reef-heavy coastal waters extending from Cape Freels westward into the vibrant bay networks of the Exploits Islands, encompassing sections of Notre Dame Bay and Hamilton Sound.
Comprehensive Coastal Transit Mapping: Delivers extensive regional charting across a notoriously complex sector of the Northeast Newfoundland coast, illustrating intricate island clusters, hidden shoals, and protective thoroughfares.
Official Bathymetric & Seafloor Data: Packed with precise depth soundings, undersea contour lines, low-tide marine benchmarks, and localized seafloor characteristics essential for managing safe draft clearance and identifying secure anchoring grounds.
Essential Aids to Navigation: Explicitly details all official maritime buoys, coastal light stations, range indicators, daybeacons, and prominent shoreline topography to guarantee high-visibility situational awareness during thick Atlantic fog or night transits.
Premium Multi-Light Legibility: Printed with vibrant, high-contrast marine inks specifically engineered to maintain absolute clarity under direct pilot house sunlight or 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.
