The Goulet de Brest is a 3-km-long strait linking the roadstead of Brest to the Atlantic Ocean. Only 1.8 km wide, the goulet is situated between the Pointe du Petit Minou and the Pointe du Portzic to the north and the îlot des Capucins and the Pointe des Espagnols to the south. At each turn of the tide, the ocean refills the roadstead in a current that can attain 4 to 5 knots. Sailing ships would thus wait in the cove of Camaret-sur-Mer for a favourable current to carry them into the goulet.
