HMHS REWA - Cornwall & Devon

The HMHS Rewa, sitting at 57 metres, is a serious dive for serious divers, no question. We’re talking full technical setup, but the reward is absolutely worth the effort. Dropping down, you’re greeted by this immense structure, 139 metres of history, appearing out of the green gloom. You can still make out the sheer scale of her, a hospital ship, and it’s a sobering thought, knowing her story. Her six boilers are a real focal point, huge cylinders encrusted with dead man's fingers and anemones, creating these incredible, colourful scenes against the steel. The bridge area is largely collapsed but the bow and stern still hold their shape well, offering plenty to explore if you’re comfortable with penetration. Visibility here can be tricky, typical for the UK, but when it’s good, the light catching the growth on the deck plates is something special. We’ve seen conger eels that look like they could swallow your arm, and lobsters tucked into every conceivable crevice. Our favourite time to dive her is on a slack tide in late summer, when the water has warmed a degree or two, and the light penetrates a little deeper. Just remember, this isn’t a quick dip; it’s a planned expedition.
