Dive One of Britain’s Most Historic World War II Underwater Sites

Join Jeff’s Diving World for an unforgettable afternoon exploring the famous World War II Valentine DD Tanks resting beneath the waters of Poole Bay near Studland, Dorset.

This fascinating dive combines history, marine life and underwater exploration as we visit one of the UK’s most significant military wreck sites. Resting in approximately 15–16 metres of water, these experimental amphibious tanks were lost during Exercise Smash in April 1944, a major rehearsal ahead of the D-Day landings.

Today the site serves as both an incredible dive location and an official war grave, so all divers are asked to show the utmost respect while visiting.

• Dive two historic Valentine Duplex Drive (DD) tanks.
• Explore one of the UK’s most famous WWII underwater sites.
• Suitable for Open Water divers and above.

Dive Site Information

The two main tanks lie approximately 60 metres apart on relatively flat sandy seabed. Shot lines are normally attached to the first tank, allowing divers to navigate comfortably between both wrecks.

Although visibility varies depending on tides and weather, the site is generally considered an excellent shallow wreck dive and is popular with photographers, historians and recreational divers alike.
