Strong winds had hoped to have calmed by this afternoon
Adverse weather conditions - which were hoped to have lifted by this afternoon - are the reason behind the Steam Packet Company's decision to delay two sailings.
The 15.00 Mannanan sailing will set off for Liverpool an hour later than planned at 16.00.
Meanwhile, the 19.15 return journey from Liverpool back to Douglas will leave at 20.00.
The 19.45 Ben-my-Chree to Heysham remains unaffected and running to time.
