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) - EMSSTROM offers some of Cornwall & Devon's richest wreck diving. Water ranges 10-18°C, warmest July, August, September.
The EMSSTROM, formerly the Frithjof, is a big wreck sitting upright at 26 metres off the Devon coast. She’s a former fishery protection vessel, a serious piece of kit built in 1968, and her size, 76.7 metres long, is immediately apparent as you descend. We found the wheelhouse and bridge area particularly interesting, with some good penetration for those qualified and equipped, though always remember she’s classified as dangerous. Since sinking in 2013, the wreck has become a solid artificial reef, attracting lots of tompot blennies, dogfish nestled in the debris, and a good few conger eels peering from the darker corners. It's a great dive for experienced wreck enthusiasts looking for something substantial and relatively intact.
