This week came further issues for the MV Lochnevis and MV Finlaggan, bringing more cancellations.
Rob McKinnon, chief executive of Outer Hebrides Tourism, said while the return of the MV Loch Seaforth was welcome, the islands have been hit hard by regular under-provision and he has written a letter to Transport Minister Graeme Dey calling for action.
He said: “With a month-long 20% reduction in capacity, the damage is not limited to the tourism sector, with empty supermarket shelves, chaos for hauliers and islanders being unable to travel.
“CalMac have had no option but to prioritise island traffic and freight, meaning tourism is particularly badly hit with space for visitors reduced by 30-40%.”
