Planned repairs to the Ben-my-Chree have been postponed.
Following advice from the manufacturers about the length of time needed to carry out the work, a planned three-day stay in dry dock, from September 30, has been cancelled.
Chief executive Mark Woodward said: 'On a positive note this does at least allow us to offer some additional Birkenhead services as well as increased freight capacity.'
He added: 'We now need to consider carefully when this repair work is best completed after taking further advice from the manufacturer about revised delivery dates.'
