The full Arran ferry service will be sailing from Troon instead of Ardrossan until Thursday at least, CalMac has announced.

A warning of easterly winds, combined with the poor condition of Ardrossan harbour, has forced MV Isle of Arran to relocate to the South Ayrshire harbour from Monday morning.

The route's second vessel, MV Alfred has already been sailing from Troon due to the closure of Ardrossan's Irish Berth earlier this year.

The final sailing from Ardrossan was at 7am on Monday.

The four day move will mean longer crossing times for passengers.

The move came on the day CalMac warned they may have to switch services to Troon permanently due to the condition of Ardrossan harbour, accusing owners Peel Ports of lack of investment in the ailing facility.

CalMac's revised timetable is: 

Depart Troon 7am, arrive Brodick 8.20am.

Depart Brodick 8.50am, arrive Troon 10.10am.

Depart Troon 11am, arrive Brodick 12.20pm.

Depart Brodick 12.50pm, arrive Troon 2.10pm.

Depart Troon 3pm, arrive Brodick 4.20pm.

Depart Brodick 4.50pm, arrive Troon 6.10pm.

The ferry operator says MV Alfred will continue sailing between Troon and Brodick to its previously published timetable throughout the disruption, with departures from Troon at 8.30am and 1.30pm and from Brodick at 10.20am and 3.20pm.
