It's due to a 'deterioration' in weather conditions
Sailings tonight (30 November) and early tomorrow morning (1 December) are facing potential disruption.
The Steam Packet Company says the 7.30pm Ben-my-Chree voyage and its return, at 12.30am on Wednesday, are subject to delays or cancellation.
It's due to a deterioration in weather conditions.
A final decision on both crossings will be made by 5.30pm this evening (30 November).
