4170 - Glace Bay Harbour | Cape Breton Nautical Navigation Map

Navigate the rugged eastern shores of Cape Breton Island with the CHS Chart 4170: Glace Bay Harbour. Produced by the Canadian Hydrographic Service (CHS), this high-resolution nautical chart is the definitive resource for mariners, commercial fishers, and recreational boaters entering one of Nova Scotia’s most historic industrial and fishing ports.

Rendered at a large scale for maximum detail, Chart 4170 provides the granular hydrographic data required for safe pilotage into Glace Bay Harbour. This region is known for its exposed Atlantic coastline and specific approach challenges; therefore, this chart offers precise bathymetry, clearly defining the dredged channels, breakwaters, and wharf facilities. It also details the surrounding coastal features and underwater hazards that are critical for vessels transiting the eastern approaches to Spanish Bay and the wider Sydney region.

Key Features include:

• Large-Scale Harbour Detail: Provides the high resolution necessary for maneuvering within the tight confines of the Glace Bay wharf and inner basin.

• Hydrographic Precision: Features authoritative depth soundings (at Chart Datum), seabed characteristics, and shoreline topography.

• Navigational Aids: Accurately plots all buoys, range lights, and coastal beacons essential for safe entry in varying weather conditions.

• Strategic Coastal Coverage: Includes the immediate approaches to the harbour, identifying shoals and rocky outcrops along the Cape Breton shoreline.

• Official Standards: An essential CHS publication that meets federal carriage requirements and serves as a vital safety standard for the Atlantic fishing fleet.
