BOUKETHALOS - Alonissos Marine Park

Boukethalos, in the Alonissos Marine Park, offers a quiet dive with a touch of melancholy. This isn't a massive warship, but a burnt-out yacht, sitting upright at 40 metres. We love how it feels like exploring someone's lost dream. Dropping down, the first thing you notice is the ghostly outline against the blue, the superstructure largely gone, leaving an open skeleton. Inside the hull, the bare ribs of the boat are now home to small groupers and cardinalfish, darting in and out of the shadows. There's an eery silence down there, broken only by your own breath. We’d suggest keeping an eye out for nudibranchs on the remaining deck fittings; they add a surprising splash of colour to the muted tones of the wreck. This dive is best for experienced wreck divers who appreciate a more intimate exploration rather than a grand, intact vessel. It’s a good one to pair with a deeper dive in the park, a reflective counterpoint to the more bustling reefs.

Wreck History - BOUKETHALOS

Vessel Type
unknown
Cause
fire

Resting in the deep, clear waters of the Alonissos Marine Park, the Boukethalos is a modern yacht that succumbed to a sudden onboard fire. An electrical short circuit sparked a blaze that quickly consumed the vessel, forcing it to be abandoned. The fire burned the yacht out before it finally slipped beneath the waves, coming to rest on the seabed 40 meters below.

As a deep dive, the Boukethalos is reserved for experienced and technical divers. The wreck sits upright and, despite the fire damage, its form is still clearly recognizable as a sleek, modern yacht. Divers can explore the charred superstructure and peer into the hull, imagining its former luxury. Located within a protected marine park, the wreck is slowly being colonized by local marine life, adding a splash of nature's color to its stark, burnt frame.
