The 84.2-metre superyacht Obsidian Hull has arrived in a windy Portland in Dorset as Storm Debi swept through.

Although the boat's owner is not yet known, the yacht is thought to be worth a huge £94 million.

A key feature of the design is an atrium staircase leading to a lower deck dining saloon where the entire wall opens to a terrace view just above sea level.

The super yacht was built by RWD, in collaboration with MONK Design in Holland.
