LE MERLE
Why dive here
With 176+ marine species recorded in the area - including blue sharks, dolphins, dwarf minke whales, humpback whales and ocean sunfish (mola mola) - LE MERLE offers some of Cornwall & Devon's richest wreck diving. Water ranges 10-18°C, warmest July, August, September.
The Le Merle, a trawler resting at 49 metres, is a serious dive for experienced wreck enthusiasts. This isn't a site for beginners; it demands careful planning and good gas management, but the rewards are significant. We love how intact she is, still sitting upright on the seabed, her mast often rising a good way towards the surface. Descending through the green, slightly particulate water, her shape slowly coalesces – a proper ship rather than just scattered debris. Inside the wheelhouse, we’ve spotted conger eels the size of small tree trunks peering out from shadowed corners, and the holds are often full of bib and pollack. Sunlight rarely reaches this depth with any real intensity, so a good torch is essential for picking out the details, like the ship’s wheel, which often remains. For those who appreciate the quiet solemnity of a deep, intact wreck, the Le Merle delivers a genuinely compelling experience. It’s a dive that stays with you, a real sense of history preserved in the cold embrace of the Atlantic.
