The Amoco Cadiz is the wreck of a supertanker located in the Molène Archipelago. The vessel lies broken across a depth range of 5 to 30 metres, with an average depth of 25 metres. This site is strictly for intermediate divers due to strong currents, potential surf, and an overhead environment within the hull sections. Visibility typically ranges from 5 to 10 metres. Access is by boat only, and divers must be aware of boat traffic when surfacing. Given the challenging conditions and tidal windows, booking with a local guided operator is essential. Divers should use appropriate exposure protection for water temperatures between 11 and 13 degrees Celsius.

The Elektra is a wreck dive located in the Molène Archipelago, resting at a constant depth of 18 metres. This site is suitable for intermediate divers comfortable with cool Atlantic conditions, as water temperatures range from 11 to 14 degrees Celsius. Access is by boat only. Divers should be aware of potential entanglement risks within the wreck structure and the presence of mild currents that can intensify outside of slack water. Visibility typically ranges between 5 and 10 metres, making a dive torch useful for exploring the structure. Proper buoyancy control is essential to navigate the wreck safely.
