Considerably Delayed Ferry from Scottish Shipyard Pushed Back for Another Six Months

24th December 2025
The Scottish shipyard saga continues with yet another delay with issues of the second of twin newbuilds, Glen Rosa, from the government-owned yard in Port Glasgow, Inverclyde, which was due to have delivered the ferry in 2018 to serve the Isle of Arran on the Firth of Clyde. The ferry is seen during its launch last year.

The second of the much-delayed and over-budget CalMac ferries has been put back again, with its Scottish shipyard, Ferguson Marine, saying it will not now arrive until late next year.

It had been hoped that the 7,040-ton newbuild twin Glen Rosa would be delivered to Caledonian Maritime Assets and then chartered to the Scottish state-owned ferry operator CalMac in the second quarter of 2026. However, a deterioration of the 102.4 m hull coating and corrosion in the stern tubes was discovered on the dual-fuel-powered ferry during a period of drydocking in August.

This setback has led to the latest delay of the 852-passenger ferry destined to serve the Isle of Arran (Brodick) route across the southern Firth of Clyde, where the first twin, Glen Sannox, also beset by delays and cost overruns, finally entered service more than six years late in January.

According to the Port Glasgow-based yard, Inverclyde, another period for the Glen Rosa will be required in drydock, but the earliest available slot is “later in 2026.”

This delayed dry-docking will have a knock-on effect, as the necessary trials and crew familiarisation are also to take place prior to the Glen Rosa’s entering into service, but it could be 2027 before islanders are served by the new ferry, which will also handle 127 cars and 16 lorries.

The National newspaper has more on this latest delay.

Shipyards

Afloat will be focusing on news and developments of shipyards with newbuilds taking shape on either slipways and building halls.

The common practice of shipbuilding using modular construction, requires several yards make specific block sections that are towed to a single designated yard and joined together to complete the ship before been launched or floated out.

In addition, outfitting quays is where internal work on electrical and passenger facilities is installed (or upgraded if the ship is already in service). This work may involve newbuilds towed to another specialist yard, before the newbuild is completed as a new ship or of the same class, designed from the shipyard 'in-house' or from a naval architect consultancy. Shipyards also carry out repair and maintenance, overhaul, refit, survey, and conversion, for example, the addition or removal of cabins within a superstructure. All this requires ships to enter graving /dry-docks or floating drydocks, to enable access to the entire vessel out of the water.

Asides from shipbuilding, marine engineering projects such as offshore installations take place and others have diversified in the construction of offshore renewable projects, from wind-turbines and related tower structures. When ships are decommissioned and need to be disposed of, some yards have recycling facilities to segregate materials, though other vessels are run ashore, i.e. 'beached' and broken up there on site. The scrapped metal can be sold and made into other items.
