The Canadian Hydrographic Service (CHS) Chart 4821 is an official, high-precision marine navigation chart designed for commercial shipping fleets, industrial cargo vessels, and regional fishing operators traversing the northeast coast of Newfoundland. This authoritative nautical asset provides critical "ground-truth" data for safely navigating the vast, deep-cut waters of White Bay and the island-dense waters of Notre Dame Bay, two of the most vital maritime zones along the province's northern peninsula.

Key Features & Hydrographic Data Included:

  • Comprehensive Multi-Bay Coverage: Delivers extensive regional charting across the expansive waters of White Bay and Notre Dame Bay, capturing intricate coastal inlets, major island clusters, and deep-water thoroughfares.

  • Official Bathymetric & Seafloor Data: Packed with precise depth soundings, shifting seafloor contour transitions, low-tide marine benchmarks, and localized hazard indicators essential for managing safe draft clearance and secure anchoring.

  • Essential Aids to Navigation: Explicitly details all official maritime buoys, powerful coastal light stations, range indicators, daybeacons, and prominent shoreline topography to guarantee high-visibility situational awareness during heavy 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.
