4505 - Harbour Plans | East Coast of the Island of Newfoundland Marine Map

Master the intricate inlets and strategic ports of the Atlantic shoreline with CHS Nautical Chart 4505. This specialized "Plans" chart provides high-resolution, large-scale mapping for several key harbours and landfalls along the East Coast of Newfoundland. While coastal charts offer broad passage data, Chart 4505 is the essential "close-up" resource required for safe docking, anchoring, and maneuvering within the rugged, rock-bound coastal communities of Bonavista Bay, Trinity Bay, and the Avalon Peninsula.

Chart 4505 features a collection of detailed insets—often at scales as precise as 1:10,000 or 1:15,000—that reveal the complex hydrography hidden within Newfoundland’s deep-water arms. It provides critical data on wharf structures, breakwaters, and the narrow, tide-swept "tickles" that connect sheltered basins to the open North Atlantic. Whether you are a commercial fisher entering Catalina Harbour, a recreational sailor seeking refuge in Trinity, or a shipping pilot coordinating logistics in the East Coast region, this official Canadian Hydrographic Service document offers the soundings and navigational aids necessary for precision pilotage.

Key Features include:

• Multi-Plan Compilation: Features detailed large-scale insets for multiple strategic eastern Newfoundland harbours (refer to specific edition for current list, typically including areas like Catalina or Port Union).

• Hydrographic Precision: Features high-density depth soundings and seabed composition essential for avoiding the "sunken rocks" common to the Newfoundland shelf.

• Navigation-Critical Infrastructure: Clearly identifies public wharves, regional lighthouses, range lights, and all essential maritime buoyage.

• Safety & Hazard Identification: Highlights treacherous ledges, submerged ruins, and the specific approach sectors required for safe entry during heavy Atlantic fog.

• Professional Grade: Produced to the rigorous standards of the Canadian Hydrographic Service (CHS) for professional navigation, harbor management, and GIS spatial analysis.
