Doulos was purchased in 1977. Since then, over 20 million visitors have been welcomed on board for tours, programmes and visits to the floating book fair. With stops in over 500 ports of call, this unique ship has visited more than 100 countries in Africa, the Americas, Asia, Australia, Europe, the Middle East and many island nations.

Constructed in 1914, Doulos is recognised in the Guinness Book of World Records as the world's oldest active ocean-going passenger ship.

The ship was sold in the first part of 2010, with handover of ownership taking place on 18 March. Over the 32 years she was in service with OM Ships, Doulos welcomed over 21 million people on board during 603 ports of call in 104 countries. During that time, the vessel covered more than 350,000 Nautical Miles—equivalent to sailing around the world 16 times!
