Caledonian MacBrayne fleet

The Caledonian MacBrayne fleet is the largest fleet of car and passenger ferries in the United Kingdom, with 34 ferries in operation, 2 on charter and another 6 on order. The company provides lifeline services to 23 islands off the west coast of Scotland, as well as operating routes in the Firth of Clyde.

Caledonian MacBrayne (CalMac) vessels can be readily identified by their black hulls and white superstructures. They have red funnels with black caps that display the Lion Rampant badge with masts in buff. The fleet can be categorised into various groups. Vessels are owned by the asset holding company Caledonian Maritime Assets Limited, which is in turn wholly owned by the Scottish Government.

Major vessels
There are presently ten vessels over 80 m in length in the CalMac fleet:

MV Isle of Arran, MV Hebridean Isles, MV Isle of Mull, MV Lord of the Isles, MV Caledonian Isles, MV Isle of Lewis, MV Clansman, MV Hebrides, MV Finlaggan, and MV Loch Seaforth (2014). These vessels usually operate on the longer crossings, with high passenger numbers.

MV Loch Seaforth (2014), at 116 m in length the largest vessel in the fleet, operates on the Ullapool to Stornoway, Lewis crossing. MV Caledonian Isles has the highest passenger capacity and can carry 1000 people on the Ardrossan to Brodick, Arran crossing. MV Hebrides crosses The Minch from Uig, Skye, while MV Isle of Mull, and MV Clansman are based in Oban, serving Mull, Colonsay, Coll, Tiree and in the summer and for relief Barra. MV Isle of Lewis is based in Castlebay, serving Barra, sailing to Oban. MV Lord of the Isles is based in Lochboisdale, serving South Uist, sailing to Mallaig. MV Finlaggan and MV Hebridean Isles serve Islay and Colonsay from Kennacraig. During the summer, MV Isle of Arran, replaced at Islay in 2011, supplements the Ardrossan - Brodick service and sails to Campbeltown. She is a spare vessel during the winter months.

Two new dual fuel ferries are being built by Ferguson Marine Engineering. The first, named MV Glen Sannox is due to enter service at Ardrossan, and is now scheduled for delivery by 31 March 2024. The second, MV Glen Rosa, is expected to be launched on 12 March 2024 and delivered by 31 May 2025. See also ferry fiasco for the political controversies surrounding the construction of these units.

Four other identical new vessels, ordered in two batches, from Cemre Marin Endustri, Turkey are due to be delivered between October 2024 and February 2025. The first two will be used on the Islay service, and will be named MV Isle of Islay and MV Loch Indaal. The second two will be used on the Uig to Lochmaddy and Tarbert routes, and will be named MV Claymore (2024) and MV Lochmor (2024). All apart from the first vessel being built in Turkey has a raised aft mooring deck due to the higher piers on the Uig Triangle.

Clyde services
The Wemyss Bay to Rothesay route is operated by two vessels, built in Poland, MV Bute (delivered in spring 2005) and MV Argyle, which entered service in 2007. There was much controversy following the decision to award the shipbuilding contracts to yards outside Scotland. The streakers' removal from Rothesay was delayed by pier work to install an end-loading linkspan, allowing full ro-ro operation.

The former Clyde ferries, MV Jupiter (1974), MV Juno (1974) and MV Saturn had provided the Dunoon and Rothesay services for the best part of 35 years. They were nicknamed the "streakers", because of their speed and ability to manoeuvre rapidly both at sea and in port. Juno and Jupiter were withdrawn from service in 2010, and by June 2011 Juno had been broken up at Rosneath, meanwhile Jupiter was sold to breakers in Denmark for recycling in that month.

From 2002, the service to Dunoon was supplemented by passenger catamaran MV Ali Cat, owned by Solent and Wightline Cruises and chartered by CalMac from Red Funnel Line. MV Saturn last served Dunoon on 29 June 2011, and was then scheduled to operate the summer relief on the Arran crossing. From 30 June 2011, the Gourock - Dunoon service was awarded on a passenger-only basis to the newly formed David MacBrayne Ltd subsidiary Argyll Ferries. Argyll Ferries purchased MV Ali Cat and a former Irish boat renamed MV Argyll Flyer to serve the route. Argyll Flyer was not available for the start of the passenger-only service due to prop shaft problems. The company leased the cruise boat MV Clyde Clipper from Clyde Cruises to start the service, but she was out of service with engine problems for most of the first day.

Loch class
The Loch class are a group of smaller vessels with a single car deck, running the length of the ship, with a ramp at each end. They vary in length from 30.2 to 54.27 m. Most are symmetrical when viewed from the side, with no operational bow or stern. Passenger accommodation is down one or both sides of the ship. MV Loch Portain, MV Loch Buie and MV Loch Shira also have a lounge above the car deck. They operate on shorter crossings, usually between 5 and 30 minutes, although MV Loch Alainn, MV Loch Portain, and MV Loch Striven take 40, 60 and 55 minutes on their respective routes, Sound of Barra between Ardmhor and Eriskay, Sound of Harris between Berneray and Leverburgh, and Oban and Lismore.

The original four Loch class vessels were based on MV Isle of Cumbrae. At 30.2 m in length, they can carry 12 cars and 200 passengers. The largest and newest, MV Loch Shira, is 54.27 by and can carry 32 cars and 250 passengers. She was built for and has run on the Largs to Cumbrae route since 2007. A mere 7 cm shorter, MV Loch Fyne and MV Loch Dunvegan were built for the Skye crossing. They were made redundant by the opening of the Skye Bridge and eventually found redeployment elsewhere after some time laid up.

Of similar design, but larger than the Loch class, MV Hallaig was launched in 2012 for the Raasay service. She is powered by a hybrid combination of batteries and a small diesel engine - a world first for a sea-going RO-RO vessel. A second hybrid ferry, MV Lochinvar, was launched in May 2013 for the Tarbert to Portavadie route. The third hybrid ferry, MV Catriona, was launched on 11 December 2015 and entered service on the Claonaig to Lochranza route in September 2016.

CMAL are currently undergoing a design and tender process for new battery-powered Loch Class ferries. The first phase is expected to consist of seven vessels being delivered between 2025 and 2028. They will be 49.9m long and have the capacity for 24/25 cars and 150 passengers or 15/16 cars and 250 passengers, depending on the design and route they will be on. There will be another phase for the ferries that do longer journeys or have port or sea constraints; these will be assigned to the Sound of Barra, Sound of Harris, Oban - Lismore and Mallaig - Armadale crossings.

Passenger-only vessels
MV Argyll Flyer (244 passengers) and the catamaran MV Ali Cat (250 passengers) are passenger-only ferries used on the Gourock - Dunoon service. The ferries, formerly operated by Argyll Ferries, were acquired when the company was incorporated into Caledonian MacBrayne in January 2019.

Other vessels
There are five vessels in the fleet which cannot be listed in the above categories.

MV Carvoria is a 12 m vessel used on the Kerrera service. She was built in 2017 by Malakoff Limited in Shetland. She is a bow loading vessel of similar design to the old Island Class vessels and can take twelve passengers and one car, although due to vehicle restrictions on Kerrera she rarely carries cars. She is the smallest vessel in the fleet. MV Coruisk is a 65 m "sheltered water vessel", operating on the Mallaig to Armadale route in summer, and relieving on the Clyde in winter. Her design allows her to make the crossing in reverse when sea conditions allow. MV Lochnevis is a highly specialised ship serving the Small Isles of Eigg, Canna, Rùm and Muck from Mallaig. She is 49.2 m long, and has capacity for 190 passengers. Her vehicle deck can accommodate up to 14 cars, but is empty on most sailings due to the lack of roads and vehicle restrictions on the Small Isles. She is instead used mostly for goods and vital equipment for the islands. Lochnevis has a surprisingly large vehicle ramp, which dominates her appearance. This allows her to berth a considerable distance from slipways, protecting her exposed Azipod propulsion systems in shallow waters. MV Loch Frisa is a former Norled ferry bought by Caledonian MacBrayne in 2021. She was built in 2015 as Utne and operated for Norled for 6 years. She is a double-ender ferry with passenger capacity for 195, and capacity for 40 cars, or 4 HGVs. She measures 50 m long by 14.5 m metres wide. Following a naming competition, CMAL announced renaming as MV Loch Frisa. MV Alfred is a 84.5 m (277 ft) catamaran ferry chartered from Pentland Ferries for 9 months from April 2023. She can carry 98 cars and 430 passengers. She operated the Ardrossan - Brodick route from May to September 2023. Berthing trials at Stornoway in October 2023 were unsuccessful. She underwent bow thruster repairs before taking over the Arran service, allowing MV Caledonian Isles to carry out berthing trials at Islay, Colonsay, Mull, Coll & Tiree. Her charter was extended by 6 months on 6 November 2023 to last until 21 August 2024. During November and December, due to a technical issue with MV Loch Portain, Alfred provided a service between Tarbert and Lochmaddy. She then partnered MV Isle of Arran on the Arran service during MV Caledonian Isles' overhaul. In July 2024 it was announce that the charter has been extended for a further six months until March 2025
