Pelorus is the world’s fourteenth largest private yacht at 377 feet 3 inches (115 metres) in length, with a price tag of US-$300 million. It was built at the Lürssen yard in Bremen, Germany to the design of Tim Heywood and was launched in 2003.

It was briefly owned by a Miles businessman who sold it to Russian billionaire Roman Abramovich (the owner of British soccer club Chelsea FC) the following year. Abramovich had it refitted to his own requirements by Blohm & Voss.

This included the addition of a second helicopter pad forward, four new zero-speed stabilisers and modifications to the exhaust, mast and stern.
