Fantastic base for wreck diving

You may be surprised to know that around 1500 wrecks have been reported missing or sunk in Dorset waters. Weymouth and Portland’s strategic position in the English Channel meant it having significant conflict in both world wars from land, sea and air. And prior to that, battles at sea with the Dutch, French, Spanish and the elements all took their toll. Indeed, over 300 ships have foundered off the Chesil Beach alone (in what came to be known as Deadman’s Bay).

Amazing variety of wrecks and reefs

The wrecks in our area include everything from naval and merchant steel ships through, submarines, aircraft, and landing craft, right back to historical sites dating from the 17th, 18th & 19th centuries. Classic wreck sites like the Salsette, Warrior II and Merchant Royal , submarines including the UB74, U332, P555, HMS Sidon and M2, and massive cargo ships such as the Aeolian Sky. Check out just a sample of the wrecks and reefs in our area in the Inshore Wrecks, Offshore Wrecks and Local Reefs pages.

Wey Chieftain IV also conducts dives on new targets identified through sidescan sonar searches. Sonar searches allow us to find much older wrecks, including those where much of the wooden structure has been lost and just the metal fragments remain. We also have a great variety of reefs in the area with a huge variety of marine life on them.

Open to all levels

Our diving is open to all levels of diver. Some of our offshore targets may be in 50-60m, but many are in less than 20-30m. We are very happy to take training trips. We are also keen to support the teaching side of diving, and happy to discuss packages to support this.


  • All divers must be qualified to dive to the maximum depth stipulated for the dive they book on.
  • Divers must be medically fit to dive, and have recent in-water experience appropriate for the level of diving to be conducted.
  • All divers must carry at least one delayed surface marker buoy (DSMB) and have the requisite training to be able to deploy that (including solo and mid-water in case that proves necessary).
  • All divers must have carried out a plan for their dive to include appropriate gas planning to ensure that they carry adequate gas to complete their dive including any planned decompression.
  • Divers must, for planned dives of 30m or more, have a viable back-up plan to ensure they carry adequate gas to complete their dive, including any planned decompression penalty, should their primary gas source be lost at any point during the dive.
