The Manannan's final voyage of the year was a rough ride last night, with several passengers describing it as horrific.
Travellers on the crossing from Liverpool to Douglas have reported damage to vehicles, with videos being widely shared online.
In a post on Facebook, one passenger said there were very frightened people on board and vomit absolutely everywhere.
Another person described how a ceiling vent became dislodged during the journey and fell onto a woman, causing a cut to her head.
