4659 - Port au Port Marine Map | Newfoundland

Navigate the sweeping, structurally complex coastal waters of southwestern Newfoundland with the official Canadian Hydrographic Service (CHS) Nautical Chart 4659. This government-certified marine navigation chart provides exhaustive hydrographic and bathymetric coverage for the historic Port au Port region, including the waters flanking the unique Port au Port Peninsula, Fox Island River approaches, and the vibrant local bays.

Drafted at a highly functional coastal operational scale of 1:41,700, Chart 4659 offers uncompromised resolution for navigating this challenging section of the Gulf of St. Lawrence. The area is renowned among mariners for its shifting shoals, exposed coastal reaches, and demanding North Atlantic weather patterns. As an essential tool for commercial fishing fleets, regional freight carriers, aquaculture operators, and recreational sailors, this chart serves as the definitive legal "roadmap" required to comply with Canadian Coast Guard vessel carriage regulations.

Every print-on-demand sheet meets strict commercial marine safety criteria, ensuring watch officers can accurately read underwater obstructions, plan harbor entry vectors, and secure safe anchorage positions.

Essential Subsurface & Hydrographic Intelligence:

• Tactical 1:41,700 Scale Bathymetry: Features a comprehensive, high-density matrix of water depth soundings and underwater contours tailored to protect deep-draft hulls from unexpected groundings.

• Seabed Density Profiles: Identifies localized bottom compositions (such as sand, rock, silt, and mud) to assist crews in selecting secure anchorages with maximum holding capacity.

• Peninsula & Shoreline Geometry: Delivers highly accurate tracking of the complex Port au Port shoreline, intertidal flats, and rugged coastal cliffs vital for precise radar positioning and visual piloting.

• Hazard Safeguards & Navigation Aids: Explicitly flags hidden reefs, shallow shoals, wash rocks, and marine hazards while monitoring the coordinates of local buoys, light stations, beacons, and markers.
