Built by the Slip shipyard at Rybinsk in Russia, but completed by Peters at Wewelsfleth in Germany in 1997, CEMBAY started life as a conventional coaster named BORNEO but was almost immediately renamed GUTSHOF. By 1999 she had reverted to her original name. In 2005, she was acquired by her present German owners and converted in Poland to become a specialised cement carrier, placed under the management of the Briese group, and renamed CEMBAY. As such, she now has a deadweight of 4,216 tonnes and is 88.2 metres in length. The same company operates similar vessels CEMSEA and CEMLUNA, both of which have visited the Clyde fairly recently.
