NameRangeDepthInformationTidal
A330 - 4039mThis British submarine was sunk as a target after colliding with the HMS Hazard.Yes
Aeolian Sky20-3030m.A fine modern and recent wreck lying off St Alban’s Head. She’s a Greek registered bulk freighter of 14,000 tons and lies on a limestone sea bed on her port side. She stands about 13 metres throughout with her bows to the South and stern to the North.Yes
Aerials20-3025m.This is one of Portland’s most exciting and rewarding drift dives on a sea bed of black shells.
Divers are advised to watch their depth as the area has a number of drop-offs.
Ailsa Craig30-4036m.This 600 ton British steamship was sunk by a torpedo in 1918 while carrying a cargo of coal. Measuring 200’ in length it was partly salvaged.Yes
Alex Van Opstel20-3030m.This 5965 ton Belgian passenger liner, 420’ with 57’ beam, sunk in September 1939 by a mine en route to Antwerp. One of the few large wrecks on the East side of the bill. Her highest point is 7 metres above the seabed.Yes
Algrave50-6054m.This 1274 British armed steamship measures 230’ by 34’ and was torpedoed and sunk by a German submarine in October 1917. 21 souls were lost on her.Yes
Arfon30-4035m.As an Admiralty armed trawler the Arfon sank in 1917 when she hit a mine. The wreck was discovered in 1998 some 7 miles out of Worbarrow Tout.Yes
Avalanche40-5046m.This 1154 iron sailing ship collided with the Forrest before sinking.Yes
Baly Bay to Grove20-3025m.This can be an exciting dive is planned correctly but divers should be aware that an outward tide will rapidly move them towards the eddy race after Grove point and beside Portland Bill.
Baly Drift20-3022m.Dropping off a boat to the left of the Hood exit from Portland harbour in outgoing tide will carry divers across a seabed scattered with shells, crabs and during the summer months much exotic sea life including a variety of nudibranches.
Binnendijk20-3028m.Dutch steamship of 6800 tons mined and sunk in 1939 just East of the adamant shoal, approximately 500’ long.Yes
Black Hawk (Bow)Oct-2015m.Torpedoed by a German sub in December 1944, towed into Worbarrow and beached. Declared a total loss in April 1945. The wreck was blown up to clear the way for the Winfrith pipeline. It is badly broken up with large pieces of machinery present and lying in a rock shingle sea bed. There are large chains on her.Yes
Black Hawk (Stern)40-5048m.As above but the stern lies on her starboard side with the prop missing and on a gravel, shingle and sand sea bed. The top is in 36 metres of water. Sunk in December 1944.
Boadicea50-6052m.This WWII destroyer is a war grave and was lost to German aircraft torpedo attack in June 1944 with 150 souls on board. She stands 6 metres high in some places. There are items of unexploded ammunition on her including depth charges.Yes
Bombardon UnitOct-2017m.This is a WWII experimental wave breaking unit apparently made for the D-Day landings sitting off the Landing Craft and can be done as part of a Landing Craft dive. The Bombardon Unit is a star shaped barges with lots of hatches.
Bottlebank DriftOct-2019m.This site is right inside of the harbour close to the Hood entrance and can offer a good drift dive at certain times of tide. The sea bed, heavily silted, is littered with bottles, cups and plates with other oddities. At times this area is used to conduct training deep dives that require a depth deeper than 18 metres.Yes
British InventorOct-2020mMined in June 1940, all that remains is the well-scattered remains of the bow section of this British oil tanker of 7101 tons. The aft portion was salvaged and converted to a new ship. Has plenty of marine life and is well broken up with only the ribs and plates showing with its highest point about 2 metres off the sea bed.Yes
Buccaneer40-5045m.This British armed tug was sunk by accident while towing a target in August 1946 and now lies on a shingle seabed uprights and intact.Yes
Cannonball run20-3025m.This area is marked with the large yellow buoys after the Hood entrance to the harbour and has a maximum depth of about 25 metres with a straight bottom layout. Tide flow in this area can give divers a drift of up to 2 knots.
Chequered FortOct-2018m.This is on the outside of the breakwater and just around the corner from the Fort. Depending on the tide, divers can get a good drift dive in this area. On descending, follow the wall down until you reach the gravel and sandy bottom at about 18 metres. There is some sea life amid the large rocks.
Chesil CoveOct-2017m.This area is covered in various sizes of metal objects, most of which came from ill-fated ships driven ashore by strong winds and tides many years ago.
There are very few tide restrictions or currents in this area, although surf and surge may sometimes make the entry and exit points require extra care. Entry into the water should be made from the slipway towards the Cove Pub as this area is reserved mainly for divers.
Going out on a bearing of 240 degrees right under slipway can be rewarding and lead to depths in excess of 17 to 18 metres.
Entering at the end of the promenade and walking down the stairs to the beach, on the other hand, should take divers to a defunct old sewage pipeline which still attracts much sea life provided they take a bearing of 270 degrees. If you follow this pipe along the top until the end, it will give a maximum depth of approximately 12 metres from where you can take a compass bearing of 350 degrees for a short distance, a new compass bearing of 90 degrees which will lead divers to a large kelp bed, over rocks and back to shore.
The most popular entrance and the one recommended by the local Council, however, is using the slipway, walking straight down to the shore and swimming out.
Countess of ErneOct-2014m.This passenger liner Paddle steamer was later converted to a coal hulk but in 1935 broke loose from her moorings and sank against the breakwater. She was built in the early 1880s and the conversion took place 1889. She is approximately 240’ long and with a 29’ beam she lies upright on the bottom.
