Goodwin Sands

Goodwin Sands, line of shoals trending northeast to southwest for 10 miles (16 km) at the entrance to the Strait of Dover from the North Sea and lying about 6 miles (10 km) off the Kent coast of England. The shifting sands form shelter for the anchorage of The Downs and are partly exposed at low water. They present a major hazard to navigation, however, and are frequently the scene of wrecks, in spite of lights and bell buoys.
