Why dive here
With 176+ marine species recorded in the area - including blue sharks, dolphins, dwarf minke whales, humpback whales and ocean sunfish (mola mola) - Marie offers some of Cornwall & Devon's richest wreck diving. Water ranges 10-18°C, warmest July, August, September.
The *Marie* sits upright at 38 metres, a non-dangerous wreck colonised by a good variety of local marine life. It’s a rewarding dive for those comfortable with deeper UK waters, offering a chance to explore a relatively intact wreck. Visibility can be a factor, so picking your day is key for getting the most out of the site. Expect to see plenty of crabs and lobsters tucked into the structure.
