    StandoutExceptional marine biodiversity

    Dive the Diligent, and you're dropping into a proper piece of history. This 1888 steamship, resting at 41 metres, is exactly what we look for in a deep wreck. We love the scale of it, the way the bows rise out of the seabed, still so recognisably a ship even after over a century on the bottom. You’ll find two massive boilers standing proud, often obscured slightly by the murk and giving it a real atmospheric feel. The visibility here can swing wildly, but when it’s good, the site offers so much to explore. Expect to see conger eels tucked into every crevice, their heads poking out from the collapsed holds. Our favourite is exploring around the triple expansion engine; it’s a brilliant scramble over the machinery, with schools of pouting darting through the superstructure. This isn't a site for beginners. We'd suggest waiting for a calm day with minimal current, and make sure your deep diving skills are sharp. The Diligent is a serious dive for those who appreciate a substantial wreck.
