Marinas

The section of the St. Lawrence between the Ontario border and the city of Trois-Rivières is very popular with boaters. It includes three fluvial lakes—Lake Saint Francis, Lake Saint-Louis and Lake Saint-Pierre—as well as the Boucherville Islands and the Lake Saint-Pierre Archipelago. There are 48 marinas in this section of the river.

Some 80 marinas allow direct access to the St. Lawrence. These leisure ports are used by sailboats and motorboats.

Marinas feature docks that are sheltered from the waves, where access is monitored. In addition to providing space for mooring, they also feature slipways so boats can be moved into the water.

This marina does not have a breakwater, as it is separated from the main channel by islands that block large waves.

A rocky point of land can serve as a breakwater, sheltering the marina from the waves of the St. Lawrence.

Marinas can be built near the port facilities of major urban centres.

Other marinas are more remote. In Paspébiac, the marina also provides access to a site of great historical significance.
