3.7.12	AREA 12 - LYME REGIS TO BUDE
3.7.12.1	This area is divided into two sub-areas. The first, Penzance, covers the Western part of the English Channel and features the major headlands of the Lizard, Start Point and the bays of Penzance, Lyme Bay and Tor Bay. The second sub-area, named Lands End, encompasses the major landfall of Bishop Rock, the Isles of Scilly, the headlands of Landsend and Lundy Island.
3.7.12.2	Penzance
3.7.12.2.1	The coastline presents a distinctive radar target and comprises rocky headlands with isolated rocks encountered in some of the bays.
3.7.12.2.2	Tidal streams off The Lizard are reasonably strong. There are numerous ports and anchorages where shelter can be sought on this part of the coast. However, apart from Dartmouth and Tor Bay, there is little shelter during strong SW Winds Eastward of Start Point.
3.7.12.2.3	Depths are mainly regular and the mariner can approach the coastline with confidence although, on parts of the coastline, isolated rocks are encountered. In conditions of strong offshore winds and ground swell, entering some of the harbours in Mounts Bay is not recommended.
3.7.12.2.4	From Penzance Bay to Lyme Bay there are a number of commercial ports, as well as small tidal harbours. Lyme Bay is used for the transhipment of liquid cargo between tankers. Within a 20-mile radius of Start Point Lighthouse some 13 381 commercial vessel movements take place annually using 263 routes. By comparison within 20 miles of Lizard Lighthouse commercial traffic levels of 19 506 movements per annum over 420 routes are encountered. Fishing and leisure craft activity is also encountered within the harbours to varying degrees.
3.7.12.3	Landsend
3.7.12.3.1	This sub-area also presents a distinctive radar target, having similar features to the Penzance sub-area, such as bold headlands and rocky cliffs, which are steep too. From Clodgy Point the coastline is lower and recedes around St Ives Bay to Godrevy Lighthouse. A TSS is established to the West, South and East of the Isles of Scilly.
3.7.12.3.2	The southwestern most danger of the Isles of Scilly is marked by Bishop Rock Lighthouse, which provides a major landfall for vessels approaching the British Isles. Mariners are recommended not to approach the Isles of Scilly, which are littered with wrecks, in conditions of low visibility.
3.7.12.3.3	The tidal streams around the Isles are not that strong. However, they do increase in strength off the main promontories. Within the Islands the traffic mainly comprises fishing and leisure craft. Commercial traffic is limited to the island ferries, although cruise liners, of increasing size and degrees of manoeuvrability, are now using St Mary's as a port of call. Within a 20-mile radius of Bishop Rock Lighthouse there are some 12 391 commercial vessel movements per year over 266 routes. This compares with some 18,390 vessel movements per year based within a 20-mile radius of Longships Lighthouse, see figure 11 below.
3.7.12.3.4	Tidal streams off Lundy, at the entrance to the Bristol Channel, are in the region of 3kts. Visibility is generally good, although sea fog does affect the area. In heavy weather shelter may be found in the lee of Lundy or in Clovelly Road. A number of small harbours lie on the north coast of Cornwall. Fishing and pleasure craft activity predominate in these harbours.
