The Cornish-built MV Seabus was built in 2007 as a 'dedicated' passenger ferry to replace the 71-year old MV Kenilworth on the Gourock – Kilcreggan- Helensburgh service, across the Firth of Clyde (Tail of the Bank). She provided the main ferry service, with crossings of Gare Loch to Helensburgh. The service is subsidised by Strathclyde Partnership for Transport. After re-tendering, the Helensburgh Pier part of the then 'triangular' route ceased and the contract for the Gourock to Kilcreggan route was awarded by SPT to Clydelink which bought the smaller MV Island Princess from Lymington , where she was a harbour excursion vessel and was sailed north to commence the 'new' service on 1 April 2012. On January 16th 2014 Seabus was renamed 'Chieftain'.
MV Seabus brought a greater degree of comfort and safety to the route with a sealed and heated passenger cabin. Larger, roomier and more comfortable than her predecessor, she has better facilities for people with mobility problems.
