The Canadian Hydrographic Service (CHS) Chart 4817 is an official, high-precision marine navigation chart designed for commercial shipping fleets, industrial cargo vessels, and regional fishing operators traversing the southeastern waters of Newfoundland. This authoritative nautical asset provides critical "ground-truth" data for safely transiting around the rugged and exposed Avalon Peninsula, charting the strategic coastal corridor extending from the eastern approaches of Bay Bulls, around Cape Race, and into the southern waters of St. Mary's Bay.

Key Features & Hydrographic Data Included:

• Critical Peninsula Transit Coverage: Delivers extensive mapping across the highly trafficked maritime lanes surrounding the southern Avalon Peninsula, including crucial transitions between the open Atlantic and major regional bays.

• Official Bathymetric & Reef Data: Packed with precise localized depth soundings, undersea contour lines, low-tide benchmarks, and hazard indicators essential for managing safe draft clearance along an unforgiving coastline.

• Essential Aids to Navigation: Explicitly details all official maritime buoys, powerful coastal light stations, fog signals, daybeacons, and prominent land 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 vessels requiring official, up-to-date hydrographic documentation.
