Overview

Nautilus is the most ambitious vessel U-Boat Worx has ever engineered: a true superyacht above the water, and a certified manned submarine below it.

On the surface, guests enjoy a retractable sundeck with freshwater pool and bar, a 50 m² lounge framed by four 4-metre circular windows, a master stateroom and four guest cabins.

Submerged, the same vessel becomes a mezzanine-level observation platform with panoramic views — diving to 150 metres and running independently for up to 55 hours.
