The 339-tonne vessel sank after a 24ft (7.32m) wave broke her bow
Organisers of a commemoration to mark the 100th anniversary of the loss of the Ellan Vannin vessel are keen to involve people from the Isle of Man.
The steam packet sank at the mouth of the River Mersey en route from Ramsey to Liverpool on 3 December 1909, killing 14 passengers and 21 crew.
A ferry will sail to the river mouth on Thursday for a service of remembrance.
Anyone wishing to attend should be at the Mersey Ferry terminal at Liverpool Pier Head before 1000 GMT on Thursday.
The service will be attended by the descendants of those killed and the Manx Chief Minister and chairman of Steam Packet Company will cast wreaths on the water.
The Liverpool Sea Cadets will accompany the memorial service and their bugler will play the Last Post and Reveille.
