Manannan and later Manxman crossings also at risk

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.
