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) - SJOFNA offers some of Cornwall & Devon's richest wreck diving. Water ranges 10-18°C, warmest July, August, September.
The *Sjofna*, a steamship built in 1918, ran aground in the fog near Fowey in 1944. What’s left of her now sits in relatively shallow water, making it a good spot for newer wreck divers or those looking for a longer bottom time. We found the wreck broken up, but you can still make out sections of the hull and superstructure, particularly around the stern. Look for the two large boilers, which are usually buzzing with wrasse and small crabs. It’s not the most intact wreck you’ll ever dive, but the history is tangible, and it provides shelter for some interesting local critters, especially on a calm day.
Safety Notes
Wreck site - avoid penetration without wreck diving certification. Watch for sharp metal and entanglement hazards.
