If such a change or cancellation is made the £2.50 administration fee is waived. Full refunds will be issued for tickets on sailings cancelled by IOSS.

Disabled Persons

Due to the design of the Company’s vessels, we do not have facilities for disabled passengers on board. Access for embarkation and disembarkation of the vessels in both Guernsey and Sark can get difficult and, because of the large tidal range of the Channel Islands, this can be anything up to 30 steps in Sark's harbour and a very steep ramp in Guernsey's harbour. For insurance reasons Company staff are unable to carry wheelchair bound passengers up or down the steps and on or off its vessels. Company staff will give assistance to disabled persons who are able to walk up or down the steps, there is a hand rail and it is wide enough to have a person along side to assist up and down the steps Sark side. 

Invalid Carriages / Mobility Scooters Plus Power Assisted Wheelchairs, Bicycles and Tricycles
