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) - SEAFORTH offers some of Cornwall & Devon's richest wreck diving. Water ranges 10-18°C, warmest July, August, September.
The Seaforth is a deep one, dropping to 56 metres off the Cornish coast. She sank in 1929 after a collision, and what remains is a classic old wreck, largely broken up but still very much a dive. You’ll find sections of hull plating and machinery scattered across the seabed, all heavily encrusted with soft corals and sponges. It’s a site for experienced wreck divers comfortable with depth, offering a genuine sense of history and plenty of nooks for conger eels, lobsters, and the occasional anglerfish. Visibility can be hit or miss, but on a good day, it’s a properly atmospheric dive.
