The ferry will operate her usual schedule, providing overnight travel from Guernsey and Jersey to Portsmouth with a daytime return.
She was in dry dock in Falmouth for a month undergoing extensive work, including a major servicing of the port main engine and gearbox, the ride control system and the alternator and an overhaul of the shaft seals.
All the life-saving equipment on board and monitoring and alarm systems were also repaired and upgraded.
