The Manannan has been fixed.
Problems with her engines last night led to the cancellation of the sailing from Merseyside, and today's journey to Belfast.
Specialists were brought in this morning to take a look at the electronic management systems, which it was thought were being affected by one of the engines not running at the moment.
The vessel left Liverpool around 12.30pm.
