CalMac has so far moved more than 650 bookings due to to sail on Friday (10th July). RMT union members who work for the ferry operator plan to strike on Friday.
CalMac is continuing to contact the remaining passengers booked to travel on Friday to try and rearrange their travel plans.
CalMac is hoping to continue to run nine of 27 routes on the day of the strike on a normal or revised timetable. Last year, on the same day, CalMac carried 28,000 passengers, around 1500 of them prebooked.
The Arygll Ferries route that links Gourock and Dunoon will operate an alternative bus shuttle service with Western Ferries.
“Our team is working extremely hard to try and lessen the impact this strike will have but we can only do as much as we can, the reality is another strike will again damage the communities we serve,” said CalMac’s Director of Pperations, Drew Collier.
“As well as rebooking passengers due to travel we are currently finalising amended timetables and would ask people to continually check our website to see what sailings are going to be running.
“If people could avoid travelling on Friday, I would urge them to think about it, as there will be significant disruption.”
The routes the company are likely to keep open are those using smaller vessels. Destinations served by its larger ferries – the Outer Hebrides, Islay, Mull, Tiree, Coll, Arran and Colonsay – are likely to face a complete shutdown.
“There are also a few occassions such as weddings and commemorative ceremonies that we have pulled out all the stops to accommodate passengers travelling to in the face of this disruptive RMT action,” added Mr Collier.
CalMac is planning to lay on additional sailings on Saturday to cope with any backlog from the strike. As well as the website, service updates can also be found via twitter @calmac_updates.
