Doulos was purchased in 1977 and sold in March 2010. Constructed in 1914, Doulos was recognised in the Guinness Book of World Records as the world's oldest active ocean-going passenger ship. Over the 32 years she was in service with GBA Ships, Doulos welcomed over 22 million people on board during 601 ports of call in 108 countries. During that time, the vessel covered more than 360,000 nautical miles - equivalent to sailing around the world 16 times!

In 2010, she was sold and converted into a luxury hotel on land in Indonesia named Doulos Phos.
