Why has the ferry left before the timetabled departure time?

Once all safety checks and procedures are completed by the crew and all passengers, who have arrived for check in on time, are onboard, the Master is permitted to depart ahead of the advertised departure time.  

You can find your latest check in time on your booking confirmation email or our timetables. Passenger and vehicle check in times vary and can be between 5 minutes and 60 minutes before the advertised departure time.
