The Steam Packet Company says damage to the fastcraft Manannan will disrupt sailings to Belfast until at least Sunday.
Today, the Manannan was late leaving Douglas after debris damaged her propulsion systems - and then suffered further delays in Liverpool as engineers carried out repairs.
On its Facebook page, the company says it's rescheduled a number of crossings to allow more time for work to be carried out.
