Technical issues have kept vessel out of service for two days
Manannan will return to service this morning after a technical issue was resolved.
The vessel has been out of service for the last two days after developing a generator fault.
Specialists were flown to the Island yesterday to carry out repairs.
Manannan will depart from Dublin at 7am and return at 10.45am as scheduled, but the 3pm departure to Liverpool and 7.15pm crossing to Douglas have both been delayed by one hour.
