    StandoutExceptional marine biodiversity

    The *Dalegarth Force* wreck, lying in around 35 metres, is a proper dive, one that truly feels like an exploration. We've spent many an hour here, finning along her length, piecing together the story of that torpedo strike in 1918. The stern section is particularly interesting, with her single boiler still prominent, and the triple-expansion engine a jumble of twisted metal. Visibility can swing wildly, as it often does in these waters, but on a good day, with a bit of sunlight filtering down, the scale of the wreck really hits you. We’ve found her to be a fantastic spot for lobsters and conger eels, often tucked into the darker recesses. Look closely for plumose anemones carpeting the deeper plates, swaying gently in the current. It’s a challenging dive, best suited to experienced wreckies comfortable with deeper air limits and cooler temperatures. Our favourite way to dive it is on a slack tide, giving you maximum time to really poke around and appreciate her history.
