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) - HMS MELBREACK offers some of Cornwall & Devon's richest wreck diving. Water ranges 10-18°C, warmest July, August, September.
The HMS Melbreak sits deep off the Cornish coast, a proper technical dive at 48 metres. We love this wreck not just for its depth, but for the story it tells and the life that now calls it home. She was a Hunt-class destroyer, sunk by a mine in 1944, and you can still see the damage that sent her down. Dropping onto the Melbreak, you’re greeted by her intact bow section, often shrouded in schooling bib and pollack. We’ve had dives where the visibility was 15 metres, and others where it was barely five, but even in murkier conditions, her imposing structure emerges from the gloom. Look out for conger eels tucked into any available crevice, their heads poking out like curious residents. The stern, while more broken up, offers fantastic penetration opportunities for those with the right training and equipment. It's a site that demands respect and planning, but rewards you with a tangible piece of history and a thriving artificial reef. We always recommend a decent bottom time to properly appreciate her scale, but remember those decompression stops will add up.
