Manannan and later Manxman crossings also at risk
The Steam Packet Company has issued additional warnings of potential disruption to its sailing schedule on Monday due to the weather forecast.
The 3pm Manannan departure to Liverpool and return sailing at 7.15pm, along with the 7.15pm Manxman crossing to Heysham and overnight sailing 1.45am could be altered or cancelled.
Earlier, the operator also cast doubt on the 8am and 1.45pm Manxman services.
It comes as the Met Office warns of gale force conditions with gusts reaching up to 50mph.
