Dive Sites around Portland & Weymouth

The dive sites listed here are in alphabetical order with depth "ranges" given for convenience only and will depend on time of tide and bottom conditions.

Name: Range: Depth: Information:
A3 30-40 39m. This British submarine was sunk as a target after colliding with the HMS Hazard.
Aeolian Sky 20-30 30m. 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.
Aerials 20-30 25m. 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 Craig 30-40 36m. 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.
Alex Van Opstel 20-30 30m. 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.
Algrave 50-60 54m. This 1274 British armed steamship measures 230' by 34' and was torbedoed and sunk by a German submarine in October 1917. 21 souls were lost on her.
Arfon 30-40 35m. As an Admirality armed trawler the Arfon sank in 1917 when she hit a mine. The wreck was discovered in 1998 some 7 miles sout of Worbarrow Tout.
Avalanche 40-50 46m. This 1154 iron sailing ship collided with the Forrest before sinking.
Baly Bay to Grove 20-30 25m. 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 Drift 20-30 22m. 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.
Binnendijk 20-30 28m. Dutch steamship of 6800 tons mined and sunk in 1939 just East of the adamant shoal, approximately 500' long.
Black Hawk (Bow) Oct-20 15m. Topedoed by a German sub in December 1944, towed into Worbarrow and beached. Declared a total loss in April 1945. The wreck was blown by explosives 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.
Black Hawk (Stern) 40-50 48m. 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.
Boadicea 50-60 52m. 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.
Bombardon Unit Oct-20 17m. 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 Drift Oct-20 19m. 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.
British Inventor Oct-20 20m. Mined in June 1940, all that remains is the well-scattered remains of the bow section of this Britich 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.
Buccaneer 40-50 45m. 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.
Chequered Fort Oct-20 18m. 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 Cove Oct-20 17m. 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 Erne Oct-20 14m. 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.
Dredger Oct-20 12m. The Dredger lies right outside of Portland Harbour within the sheltered bay of Balaclava (in front of the large winch). This is believed to be a sand dredger and it makes an excellent shallow dive and training site in almost all weather and sea conditions. The wreckage is pretty much broken up.
Earl of Abergavenny Oct-20 15m. This is an East Inidiaman that struck the Shambles bank and sunk in front of Weymouth in 1805 with a large loss of life. Please be careful while diving this wreck and do not touch artefacts as it is currently a study project.
Elena R 20-30 27m. This 4500 ton Greek steamship was mined in November 1939 during its voyage to Antwerp. It measures 370' to 53' and was salvaged, is broken. The seabed is made out of shifting gravel and parts of the wreck stand 7 metres high.
Elmcrest 50-60 60m. A 4343 steamer she was sunk in July 1940 by a German E-boat.
Empress of India 40-50 45m. This 14,100 ton battleship was used as a gunnery and torpedo target and sank as result of this, turning turtle following several hits. Partly salvaged, lies on a sand sea bed.
Enecuri (Spaniard) Oct-20 13m. This 3000 ton Spanish steamship dragged her anchor in a Force 9 gale in December 1900 and was grounded on the rocks close to the Breakwater where she slipped and eventually sank. It is badly silted and fairly broken up but is full of marine life.
Ethel 30-40 38m. A well-broken steamship of about 2000 tons standing 6 metres off the sea bed.
Ferry Bridge 0-10 6m. This is the areas most interesting and colourful shore dive but is tide dependent. Maximum depth is about 6 to 7 metres depending on the state of the tide. Slack water is +1/2 hours HW Portland or -4 Hours HW Portland.
Fisgard II 60-70 65+ This 6010 ton ship was launched in 1870 named Invincible and operated for some time as the Erebus. In September 1914 while being towed to Portland she listed and sank with the loss of 21 souls. Her highest point is at 47 metres and she is reported to be lying upside down against a high reef.
