    Matrisha is a wreck that truly tells a story, a real standout on Ireland’s South Coast. She ran aground back in '91, a 79-meter carrier that had already seen a few name changes, Duisberg, Coburg, Boberg. We love how her size gives you so much to explore. Dropping down to just 17 meters, it’s a site that feels substantial without demanding deep experience. What makes Matrisha so good is the way she’s opened up. Much of the superstructure has collapsed, making for easy penetration into cargo holds, and we've spent countless dives just drifting through the open spaces. You'll often find conger eels peering from every dark corner, and the metalwork is thick with jewel anemones, creating these vibrant, almost painted sections. Visibility here can be temperamental, as is often the case in Ireland, so we’d suggest aiming for a slack tide and a calm day for the best experience. When it's clear, the light filtering through the broken decks is incredible, illuminating schools of pollock that dart in and out of the shadows. It’s a site that rewards multiple visits, always showing you something new.
