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) - GIRDLENESS offers some of Cornwall & Devon's richest wreck diving. Water ranges 10-18°C, warmest July, August, September.
Diving Girdleness is a proper journey back in time. This steamship, once the Grelisle and Rockabill before her final name, went down in 1918. She’s a big wreck, over 100 meters long, and that size really makes a difference. Dropping onto her, you’re greeted by the sheer scale of the cargo holds, now open to the ocean. We love how the two huge boilers stand proud, acting like apartment blocks for lobsters and conger eels. Exploring Girdleness means navigating her structure, finding gaps and passages that hint at her former life. The triple expansion engine is a fantastic focus for a dive, often draped in dead man's fingers. Visibility here can swing wildly, but on a good day, the light filtering down through the holds is quite atmospheric. It’s a site that demands decent dive experience, given the depth and potential for currents. Our tip: pick your slack water window carefully for the best chance to really soak in the history here.
