MV Hallaig is a pioneering Diesel Electric Hybrid ferry built for the Caledonian MacBrayne service between Skye and Raasay.

Hallaig was launched in December 2012 at Ferguson Shipbuilders in Port Glasgow by Deputy First Minister Nicola Sturgeon.

[3] The Clydebuilt Hallaig began her first sea trials on 5 August 2013, eight months after her launch, although she had moved in and out of dry dock in Greenock under her own power in July 2013.

The delay in her entry to service was caused by a last minute change in fire safety regulations which required her and her sister Lochinvar to have insulation fitted extensively to exposed steel and aluminium on board.

In April 2014, Hallaig temporarily relieved on the Mallaig-Armadale service after MV Coruisk was involved in an incident at Dunoon and had to have her bow extensively rebuilt.
