The Red Jet service has resumed its normal timetable.
A reduced service has been in place because of mechanical problems on Red Jet 4 and maintenance on Red Jet 7.
Leanna Lakes, Operations Director at Red Funnel, said:
“Following repairs undertaken by our specialist marine contractors and engineers Red Jet 4 is now available for service.
"Red Jet 7 has also successfully completed her annual docking and associated maintenance work. We have reinstated our full timetable, Red Jet 6 and Red Jet 7 will be delivering this from Thursday morning. Red Jet 4 will be back in service later in the week.
"We would like to thank customers for their patience whilst our team has been working hard to resume normal service.”
