    The Foremost 45 isn't just a dive; it’s a tangible piece of history sitting on the seabed. She was a self-propelled barge, carrying coal, when she hit a mine in November 1941, settling quickly and shallow. That shallow depth, 11 metres, is what makes her so special for us. We love the way the light filters down, even on a cloudy day, illuminating the wreck’s skeletal remains. You can really get a sense of her shape, the bow and stern still distinct, and the engine room is often accessible, a dark maw inviting exploration. It’s not about huge pelagics here; it's the smaller, more intimate encounters we cherish. Conger eels are often tucked into dark crevices, their heads poking out warily, and the anemones, in particular, are brilliant – jewel anemones creating dazzling patches of colour across the metal. Our favourite time to dive her is on a slack tide, mid-week, when you often have the whole site to yourself. It’s a wonderfully atmospheric dive, perfect for photographers or anyone who enjoys feeling a direct connection to the past.
