Description
Commercial aluminium semi-submersible passenger vessel for sale in Mallorca, Spain.
Built in 1990, this distinctive vessel was designed for coastal sightseeing and underwater observation excursions, carrying up to 10 passengers. Its upper structure remains above the waterline, while passengers are seated inside the observation compartment below the waterline.
The vessel measures 7.00 metres in length with a beam of 4.40 metres. It is powered by a single 45 HP SOLE diesel engine with approximately 40 operating hours. The engine was replaced shortly before the vessel was placed ashore, and the installation is documented and approved by the relevant Spanish vessel inspection authority.
