The Steam Packet Company has confirmed that the final sailing today and one tomorrow have been cancelled.
The Manxman's 8.30pm trip from Douglas to Heysham has been called as well as her return trip at 2.15am tomorrow morning.
The decision comes as Storm Bert continues to hit the Island with strong winds and heavy rain.
All sailings until Tuesday morning also face possible cancellation with decisions being made daily by the ship's master on whether trips can go ahead.
