HMSM P555

The HMSM P555 is a proper dive, a deep shot that really makes you feel like you’re exploring. We love how intact she is for a wreck of her age. Dropping down to 40 metres, you first make out the conning tower, then the full 66 metres of her length stretches out, surprisingly complete. You can still see the torpedo tubes at the bow and stern, and the gun mount forward of the conning tower. It’s a dark dive, as you’d expect at this depth in British waters, but the visibility here can be surprisingly good on a calm day, giving the whole submarine a ghostly silhouette. Life around the P555 is prolific. The wreck acts as a huge artificial reef. Conger eels are a common sight, peering out from open hatches and crevices. We’ve spotted massive ballan wrasse patrolling her decks, and ling often lurk in the deeper sections. It’s a site for experienced divers, no doubt about it, with the depth and potential for currents. Our favourite way to dive her is on a slack tide, giving you plenty of time to explore the exterior, tracing her length from bow to stern and imagining her operational days. It’s a deep, contemplative dive that rewards patience and a good eye for detail.
