Navigate the central corridor of the Magdalen Islands (ÃŽles-de-la-Madeleine) with the professional precision of the Canadian Hydrographic Service (CHS). Chart 4958 is the definitive "road map" for mariners transiting between the bustling administrative hub of Cap-aux-Meules and the scenic, ecologically rich waters of Havre-aux-Maisons.
As the primary link between the archipelago and mainland Quebec and Prince Edward Island, these waters are home to a constant flow of ferry traffic, industrial shipping, and a massive commercial fishing fleet. CHS Chart 4958 provides the high-fidelity data required for:
Large-Scale Harbour Detail: Offers the most accurate depth soundings and seafloor characteristics for the Port of Cap-aux-Meules—essential for the safe docking of CTMA ferries and large cruise vessels.
Intricate Coastal Bathymetry: Provides the granular data needed to navigate the shallow lagoons and shifting sandbars that define the entrance to Havre-aux-Maisons.
Ferry & Shipping Lane Safety: Clearly marks the lateral buoys, range lights, and navigational aids that guide high-volume traffic through the island's central transit zone.
Seabed Characteristics: Identifies the nature of the sea bottom, providing vital information for anchoring in the varying conditions of the Gulf of St. Lawrence.
With the growth of sustainable island tourism and the development of Atlantic ocean resources, the role of Chart 4958 is more vital than ever. Whether you are a ship's pilot, a commercial lobster fisherman, or a recreational sailor touring Quebec’s maritime regions, this official CHS chart provides the "ground-truth" data required to ensure the safety of your vessel, crew, and the sensitive island environment.
