    The Maggie B, formerly the Gilsea, sits upright at 45 metres off the South Coast of Ireland, a fishing vessel built in 1989. For us, this wreck is pure exploration. We love dropping down onto her, seeing the trawler’s stern, the propeller still there, and the wheelhouse surprisingly intact. There's a real sense of history, a quiet echo of her working life before she went down. She's not a massive wreck at 15.8m, but the compact nature makes for a rewarding dive. We often find conger eels peering from the deeper recesses of the engine room, and the deck, now draped in soft corals, is a favourite hangout for squat lobsters. It's a deep dive, no doubt, so suitable for experienced wreckies with appropriate training and gas. You'll want to be on your game for this one, but the visibility here can be surprisingly good, sometimes 15 metres, which really lets you take in the whole scene. Our tip: aim for a slack tide; the currents here can be lively.
