Daily commuters on the Rothesay-Wemyss Bay ferry service saw their journeys disrupted after technical problems forced one of the route’s two ships out of action.
CalMac Ferries’ MV Bute was confined to port on Monday afternoon while the issue was investigated, leaving MV Argyle to handle all the traffic on her own.
The problem persisted into Tuesday morning and saw MV Bute’s first two trips of the day, leaving Rothesay at 0625 and 0800 and departing Wemyss Bay at 0715 and 0845, cancelled as a result.
The vessel conducted trials in the Firth of Clyde first thing on Tuesday and was able to return to service with the 0930 departure from Rothesay.
A CalMac Ferries spokesman said: “MV Bute experienced issues with its onboard radars on Monday afternoon resulting in the vessel’s master deciding to berth in Rothesay.
“After investigation the likely cause was put down to interference from the excessive atmospheric activity experienced in the area yesterday.
“An upgraded radar shield to protect against this has now been fitted and after successful sea trials on Tuesday morning the vessel is now fully back in operation. We will continue to monitor the situation.”
