Manche - English Channel
The port consists of Grande Rade, an outer roadstead, and Petite Rade, an inner anchorage area. Grande Rade is protected by three breakwaters. The W breakwater, Dique de Querqueville, extends 0.7 mile ENE from a point on the shore located close SE of Fort Querqueville. The N breakwater, Dique Centrale, is about 2 miles long and detached. The E breakwater, Dique de l’Est, is about 1 mile long and extends N and NW from the shore. Its S end covers at HW.
Petite Rade, enclosed by Grande Rade, is protected on the W side by a breakwater, Digue du Homet, and on the E side by a jetty, Jetee des Flamands. Port Militaire lies on the W side and Port de Commerce lies on the E side. Basins used by small craft, yachts, and fishing vessels lie on the SW side in Chantereyne harbour in the town centre.
Tides rise about 6.4m at springs and 5m at neaps. About 3 miles N of Digue Centrale, the E current begins 3 hours 30 minutes before HW and the W current begins 2 hours 15 minutes after HW. Both currents attain a maximum velocity of about 3 knots at springs. Closer to the breakwater the currents start earlier and their rates decrease.
