HSC Cecilia Payne is a high-speed ferry owned and operated by Baleària.

Cecilia Payne was constructed by Austal Ships in Henderson, Australia,[1] at a cost IR£29 million.

These officers refused to operate the vessel at lower manning levels which had been proposed by Irish Ferries.

Irish Ferries threatened to sell or charter Jonathan Swift if the issue was not resolved.

The vessel has spent its entire career on this route, operating alongside the company's conventional ferries.
