HMS Starfish - North Sea Coast

The HMS Ocean is one of those wrecks that just screams history. It’s a Canopus-class pre-dreadnought battleship, sunk in 1915 during the Gallipoli campaign, and she rests in the Alonissos Marine Park. We love sites where the past really comes alive, and dropping down onto this one, you can almost feel the weight of its story. As you descend, the sheer scale of the ship begins to emerge from the blue. While its exact depth isn't widely published, it’s a dive that requires some experience due to depth and potential currents. The wreck is largely intact, with massive guns still in place, covered in sponges and anemones. You’ll weave through the superstructure, exploring the deck and what remains of the bridge. Common brittlestars cling to every surface, their arms swaying with the gentle surge. It’s a photographer's dream, especially when the light filters down through the Mediterranean water. Our favourite part is always finding those smaller details, like the portholes still visible or the deck fittings that hint at its former life. This isn't a quick peek-and-go; it's a dive that rewards slow, deliberate exploration. We’d suggest going with a local guide who knows the wreck intimately. They can point out areas you might otherwise miss and tell you more about its incredible history. This dive suits advanced divers who appreciate historical wrecks and aren't afraid of a bit of depth.
