4663 - Cow Head to Pointe Riche Marine Map

Navigate the rugged, exposed coastal waters of northwestern Newfoundland's Great Northern Peninsula with the official Canadian Hydrographic Service (CHS) Nautical Chart 4663. This government-certified maritime navigation chart provides exhaustive bathymetric and hydrographic coverage for the critical transit corridor extending from Cow Head north to Pointe Riche (near Port au Choix).

Drafted at a highly detailed coastal transit scale of 1:144,000, Chart 4663 is an essential legal "roadmap" for commercial fishing fleets, regional freight operators, Coast Guard vessels, and high-latitude expedition mariners traveling through the Gulf of St. Lawrence. This stretch of the Newfoundland coastline is notorious for its unforgiving North Atlantic winds, shallow limestone shoals, and heavy seasonal sea ice. To ensure vessel carriage safety and mitigate hull risks far from major drydocks, this chart provides the precise marine intelligence required to plot secure routes, time coastal runs, and locate critical harbor refuge zones.

Decisive Hydrographic & Subsurface Cartography:

• Tactical 1:80,000 Scale Bathymetry: Features a dense grid of highly accurate depth soundings and intricate underwater contours designed to safely guide deep-draft commercial vessels past rocky coastal shelves.

• Seabed Density Profiling: Logs localized sea floor characteristics (such as mud, sand, gravel, and jagged rock), giving watch officers critical data for establishing secure anchorages during sudden Atlantic gales.

• Shoreline Geometry for Visual & Radar Piloting: Provides precise tracking of low-lying subarctic coastlines, prominent headlands, and the unique topography of the Pointe Riche peninsula, enabling flawless radar alignment and visual navigation.

• Comprehensive Navigation Hazards & Aids: Explicitly highlights hidden shoals, washing reefs, and maritime obstructions while providing up-to-date tracking for remote lighthouses, fog horns, light stations, and buoys.
