Why dive here
With 169+ marine species recorded in the area - including dolphins, dwarf minke whales, humpback whales, ocean sunfish (mola mola) and octopuses - H.M.S. Martin offers some of West Coast's richest wreck diving. Water ranges 8-17°C, warmest July, August, September.
The H.M.S. Martin isn’t just a pile of metal on the seabed, it’s a time capsule. We think it’s one of Ireland’s most compelling wrecks, a British destroyer sunk in 1942, now resting in deeper, often chillier waters off the west coast. Diving it feels like entering a different world, the light muted, the silence profound. What we really love about the Martin is how intact sections remain, allowing for genuine exploration. You can still make out the gun turrets, parts of the bridge structure, and the outline of her stern. It’s an immersive experience; we've spent entire dives just tracing her decks, imagining her final moments. The wreck is heavily colonised, of course. Pink sea fans bloom from the steel, and we've regularly seen large schools of Pollock and cod weaving through the superstructure. Keep an eye out for the elusive European common squid hovering near shadowy overhangs. This site suits experienced divers comfortable with deeper, often low-visibility conditions and stronger currents. It’s not for the faint of heart, but the rewards are substantial. Our top tip: aim for slack tide, and don't rush it. Take your time to absorb the history and the vibrant life that now calls this incredible wreck home.
