After spending some time laid up in Portsmouth she returned to service on the Newhaven-Dieppe run before being chartered to the Isle of Man Steam Packet Company, which had by then been sold by Sea Containers.

In May 2008, it was announced that the Isle of Man Steam Packet Company had purchased Incat 050 (now Manannan), and it would replace Viking from the 2009 season.

She did not leave until 23 July [year needed] due to a leak that was found when her fuel tanks were being filled for her long voyage.

The port side of Viking has lost the web address, "steam-packet.com", due to re-painting following the insertion of the side-loading vehicle door.

Starting from April 2016, it operates on the Rafina - Cyclades line, calling at the ports of Tinos, Mykonos, Paros, Ios, Santorini.
