4654 - Lark Harbour & York Harbour (Bay of Islands) Nautical Chart

Execute flawless coastal pilotage through the south arm of western Newfoundland's premier waterway with the official Canadian Hydrographic Service (CHS) Nautical Chart 4654. This highly detailed, government-certified marine map provides exceptional high-density hydrographic coverage for Lark Harbour and York Harbour, nestled along the scenic and rugged outer rim of the Bay of Islands.

Drafted at an ultra-precise, large tactical scale of 1:12,000, Chart 4654 delivers uncompromised resolution for navigating these critical geographic harbors. Known for their steep mountain backdrops, sweeping winds, and narrow shoreline approaches, Lark Harbour and York Harbour are essential operational shelters for commercial fishing vessels, local freight transporters, recreational sailors, and regional eco-tourism operators. As the historic pilot station for vessels transiting inland toward Corner Brook, this sector requires rigorous precision to avoid shallow coastal shelves and sudden underwater hazards.

Notably, Chart 4654 represents a milestone in maritime safety as part of the Canadian Hydrographic Service’s modernization pilot program, delivering crisp, highly scannable cartographic data engineered to meet strict commercial vessel carriage requirements.

Elite Marine Intelligence & Navigation Features:

• Large-Scale 1:12,000 Precision: Delivers tight, high-resolution bathymetric data points and depth contours, ensuring deep-draft hulls and local commercial operators can confidently clear shallow entrance channels.

• Seabed Density Profiling: Captures localized seafloor characteristics (such as mud, sand, rock, and gravel) to guide watch officers to the safest anchoring configurations within the protected pockets of Lark and York Harbours.

• Complex Shoreline Geometry: Features highly accurate coastal configurations, prominent cliffs, and local intertidal zones vital for visual piloting and precise marine radar alignment.

• Hazard Safeguards & Navigational Aids: Highlights underwater rocks, shoals, wash-zones, and maritime obstructions while tracking the coordinates of local beacons, light stations, buoys, and markers.
