The biggest privately-owned yacht in the world has arrived in London. The mighty ship, which is 644ft long and offers a non-stop cruise visiting all seven continents, is powering up the River Thames. Guests can spend as long as they want on board, with the average owner spending three to six months.
After leaving London the ship, called The World, will set sail to Belle-Île-en-Mer, in France, followed by Spain, the Mediterranean and the Middle East.
It will also tour Africa and several countries in Asia.
