The Boreas, a yacht sunk by fire off Langeland in '72, is a surprisingly good dive. It’s not deep, just 11 metres, which means plenty of bottom time, and the visibility here can be surprisingly good on a calm day. We love that it’s still very much a yacht; you can make out the lines of the hull, the cabins, and even some of the deck fittings. It’s totally encrusted now, a sort of art installation of mussels and anemones, which provides fantastic shelter for crabs and small gobies. Exploring inside the burnt-out shell is a fun challenge, though we’d advise a good light to really appreciate the colour. Our favourite is spotting the flatfish camouflaged against the sand nearby. It’s a tranquil, unassuming dive, perfect for newer wreck divers or those who appreciate a bit of history without strong currents or extreme depths. Head out on a sunny day after a few days of settled weather for the best chance of clear water.

BOREAS Wreck History

Year Sunk

1972

Vessel Type

unknown

Cause

fire

Resting in the shallow, clear waters off the Danish island of Langeland, the wreck of the yacht Boreas offers a fascinating and accessible dive. Its story is a relatively recent one, ending abruptly on July 26, 1972. While navigating near Bagenkop, a fire broke out on board. Despite efforts to control the blaze, the vessel was overcome and sank to the seabed just 11 metres below. Today, divers can explore the remains of this modern vessel, though caution is advised. The site is officially classified as a 'Dangerous Wreck,' suggesting potential entanglement hazards or structural instability, making it a dive that requires careful planning despite its shallow depth.
