The Steam Packet says it's cancelled a total of four sailings because of bad weather today, Saturday, April 4.
Manxman's 2.15pm sailing from Heysham to Douglas won't be going ahead, and neither will her return at 7.45pm.
Meanwhile the company has also announced Manannan's 3pm voyage from Douglas to Liverpool is cancelled, as is her planned 8pm return to the capital.
It comes as Ronaldsway Met Office has a yellow weather warning for severe gales in place from 5pm until 11pm this evening, when Storm Dave hits the Island.
