Breton Sea

The western approaches to the English Channel lie between Brittany and Cornwall, open to the Atlantic swell. Ushant off the Breton coast and the Isles of Scilly to the north mark the entrance to the narrowing sea. Islands, reefs and strong tidal streams require careful navigation, particularly when westerly winds meet an ebbing tide. Ships passing these shores enter the route towards the Channel ports and the North Sea beyond.
