Sunday departure from Belfast will now be a six-hour crossing
A number of this weekend's Manxman sailings have been rescheduled due to tidal conditions in Douglas.
Tomorrow's 2.15am crossing from Heysham will now depart at 1.30am, while Sunday's 2.30am departure from Belfast will have an extended crossing time of six hours, with the vessel not arriving into the Manx capital until 8.30am.
Later sailings on Sunday have also been pushed back to accommodate the tides.
Manannan's crossings are unaffected.
