The Caledonian-Isles, integral to the Ardrossan-Brodick route, has recently undergone significant repairs and upgrades, following critical investigations and trials aimed at enhancing its operational efficiency. The vessel was taken out of service as of September 7 due to ongoing investigations held in Edinburgh, specifically at the Imperial Drydock of Dales Marine Systems. During this period, service interruptions left travelers dependent on alternative vessels such as the 'Glen Sannox' and 'Alfred', which temporarily took over operations for the Troon-Brodick route.
After completion of key repairs, the Caledonian-Isles exited drydock in Leith on September 17. The focus now shifts towards conducting a series of essential checks and trials, addressing an earlier instability issue that had been identified during sea trials in June. The inconsistency observed in the controllable pitch propellers (CPP) necessitated timely interventions, which were conducted throughout late July, leading up to the recent trials scheduled for September 18 and 19.
Assuming the repairs and re-engineering are successful, the vessel will return to the west coast for a series of familiarisation trials at Ardrossan and Brodick ports, aiming to prepare the crew for resumed operations after a lengthy hiatus. In a much-anticipated development, the Caledonian-Isles is set to resume its services on October 1. The timetable will include departures from Ardrossan at 5:00 p.m., arriving at Brodick at 5:55 p.m., with return sailings scheduled shortly thereafter.
Passengers are reminded that the sailing will operate on a turn-up and go basis, with tickets available for purchase directly at the port. Check-in times are crucial, closing 30 minutes prior for vehicles and 10 minutes for foot passengers. While onboard catering will be limited, the restoration of this service marks a significant milestone for both the ferry operator and the traveling public relying on this vital connection between the mainland and the Isle of Arran.
