The Steam Packet Company says two sailings today which had been at risk of disruption will go ahead as planned.
Forecast gales meant the 8.45am Manxman sailing from Douglas to Heysham and her return trip at 2.15pm were both at risk.
However, both crossings will depart as normal.
A decision is expected later about the 7.45pm Douglas to Heysham trip and 2.15am return – the master is due to reveal whether they’ll go ahead by 5.30pm today.
Tuesday's sailings are also threatened with disruption.
