WORK to tackle undermining of the structure of Rothesay pier will cause further disruption to the Caledonian MacBrayne ferry link with Wemyss Bay at the end of this week.
Divers will be working overnight on Thursday, Friday, Saturday and Sunday to try and repair damage to the east berth at Rothesay pier caused by the 'scouring' actions of MVs Bute and Argyle.
It is hoped the problem can be solved by putting some 350 tonnes of rock armour in place around the pier's structure.
As a result of the works, on Thursday evening the 6.15pm departure from Rothesay will sail to Gourock, and the 7pm from Wemyss Bay will be cancelled.
On Friday, Saturday and Sunday, the 7pm sailing from Rothesay will be diverted to Gourock and the 7.45pm from Wemyss Bay will be cancelled.
All other sailings will operate as normal.
The disruption to the service comes in the same week as changes were introduced to the daytime off-peak timetable on the Rothesay-Wemyss Bay service.
The revisions to the timetable, which began on Tuesday, see ferries depart both Rothesay and Wemyss Bay mostly on the hour, every hour between 11am and 4pm, while the first weekday departure from Rothesay has been brought forward slightly and now leaves at 6.25am.
There are a couple of minor exceptions to the 'on the hour, every hour' off-peak rule, most notably on Sunday afternoons to allow crew to carry out regular safety drills.
Copies of the new timetable are available at CalMac's Rothesay and Wemyss Bay offices, on board the ships themselves and can be viewed online here.
A week of change for the Wemyss Bay service was completed on Tuesday when, despite some concerns, a new Portakabin ticket office was opened at the mainland port.
Drivers buying tickets at Wemyss Bay will now have to leave their vehicles to make the purchase, rather than being visited by a mobile ticket seller.
