How long before a sailing can I embark?

Generally boarding begins approximately 30-60 minutes before our published departure times for both foot passengers and vehicles unless otherwise stated.

On busy high-season sailings loading may commence earlier to allow for correct loading of all vehicles.

If you are travelling with a pet or have any special requirements you will need to arrive at the port 90 minutes before departure.
