    StandoutExceptional marine biodiversity

    The HMS James Fennel wreck, sitting at 22 metres, is a cracking dive for anyone looking for a piece of Cornish history. She’s a former trawler, built in 1918, and what we love most is how much of her remains intact, considering she ran aground back in 1920. You can still make out the distinct lines of the hull, and the triple-expansion engine and single boiler are particularly striking, almost eerie in their preservation. What you'll find here is a genuine exploration. Spend time poking around the engine room, or follow the bow, which is often swarming with schools of pollack. We’ve seen conger eels peering out from gaps in the plating, and the resident crabs are always a good laugh to watch scuttling across the deck. For divers who appreciate history and a good rummage, this wreck is our pick for a satisfying afternoon. Just be mindful of the currents, they can pick up quickly here, so planning your dive around slack water is always a smart move.
