With severe gales forecast for tomorrow (Tuesday) things aren't looking good for the Steam Packet's sailings.
The company is warning they are likely to be disrupted and possibly even cancelled.
The Met Office is again predicting winds up to severe gale force nine in the Irish Sea.
Passengers are being advised to transfer to other sailings if they are booked to go on any of Tuesday's services, or the 2.15am crossing in the early hours of Wednesday morning.
A decision on whether the boats will go is expected at 7am.
