Pelorus is one of the largest private yachts in the world at 377 feet 3 inches (115 metres) in length. She was built at the Lurssen yard in Germany and was launched in 2003. She was briefly owned by a Saudi businessman who sold her to Russian billionaire Roman Abramovich the following year. Abramovich had her refitted to his own requirements by Blohm & Voss. This included the addition of a second helicopter pad forward, four new zero-speed stabilizers and modifications to the exhaust, mast and stern.

Pelorus is powered by two 3,600-hp Wartsila engines. Details about the interiors are scanty as Abramovich is protective of his family's privacy and highly security conscious, but they were designed by Terence Disdale. Security features include a submarine for detecting limpet mines and a missile-detection system. (1) In 2005 Abramovich lent Pelorus to Frank Lampard and John Terry for two weeks as a bonus for being the two best players at his English football club Chelsea F.C. the previous season.

Abramovich owns two other superyachts, Le Grand Bleu and Ecstasea.
