    StandoutExceptional marine biodiversity

    The Coronation Inshore site is pure history, right under your nose. At just five meters deep, this isn't about vast wreck penetration, it's about connecting with a specific moment in time. We’re talking about the remains of a 17th-century English warship, foundered in a gale in 1691. It feels like swimming through an archaeological dig. You’ll see 64 cannons, cannonballs, and big bronze pulley wheels scattered across the seabed, all still bearing the Royal Navy’s broad arrow. The scale of these items, even after centuries, is striking. We love picking out the details, imagining the chaos of that storm. This site suits divers who appreciate historical context over dramatic intact structures, and the shallow depth means long bottom times to really take it all in. While it's not a coral reef, the marine life here is surprisingly engaging. Wrasse dart among the iron, anemones cling to the old wood, and sometimes a curious dogfish will nose around the cannonballs. It’s a gentle, reflective dive, best done on a calm day with good light to really appreciate the details on the seabed. Definitely one of our favourite shallow wrecks for its story.
