Lifeline freight deliveries to the islands are being delayed on the mainland as it is now almost impossible for hauliers to get to the new earlier freight ferry service in time.
CalMac have this week implemented a new overnight freight service between Stornoway and Ullapool on MV Loch Seaforth, which is two hours earlier than the previous service operated by MV Clipper Ranger.
This means that lorries collecting goods from local supermarkets in central Scotland struggle to make the 2.30am ferry which would allow them to have the cargo in Stornoway first thing in the morning.
The result has been empty supermarket shelves until after lunch, major logistics problems for local hauliers and concerns about the long term impact on the economy.
Hauliers are this week calling for CalMac and Transport Scotland to be flexible in setting a timetable.
