The CalMac ferry, mv Isle of Lewis,  is tomorrow (Sunday) due to set off to provide cover on the NorthLink service between Scrabster in Caithness and Stromness in Orkney as part of a reciprocal arrangement which saw the mv Hildesay running the overnight freight service last October/November on the Stornoway-Ullapool route.   

The mv Isle of Lewis is due to depart Stornoway tomorrow (Sunday) to take up the service early next week and is due back in around two weeks, a spokesman for the David MacBrayne Group said.
