Cermona II

Cermona II is a wreck dive on Gran Canaria's west coast, the vessel lying in the accessible depths that make it suitable for beginner divers encountering artificial reef diving for the first time. The Roman numeral in the site's name hints at the local dive community's familiarity with the wreck: a second vessel associated with the Cermona name, perhaps a second sinking or a vessel associated with an earlier one, now resting as a permanent fixture of the underwater landscape. Wrecks in Gran Canaria's clear Atlantic waters transform quickly from sunken vessels into thriving artificial reefs, the process of biological colonisation proceeding faster in these warm, productive waters than in colder Atlantic environments. Cermona II has progressed through this transformation in the years since its sinking, its hull and superstructure now providing structure and surface for the encrusting organisms — sponges, sea squirts, anemones, and the serpulid worms that cover every suitable surface in calcified tubes — that create the artificial reef community. The wreck's superstructure and deck fittings are identifiable through the encrustation, giving the dive the narrative interest of a recognisable vessel rather than a shapeless underwater structure. Penetrating the hull's accessible sections, or simply cruising along the exterior to observe the marine life that has colonised every surface, provides a satisfying dive of genuine variety. Schools of common two-banded seabream and salema move through the wreck in loose formations, while large moray eels occupy holds and gaps in the hull with territorial assurance. Common octopus are reliably present on Gran Canaria wreck dives, their camouflage pressed against the encrusted metal in near-perfect mimicry of their substrate. The surrounding sandy seafloor hosts the invertebrate community typical of Gran Canaria's sheltered western coast. A beginner-friendly introduction to Canarian wreck diving.
