As the shipyard ferry fiasco in Scotland continues, ministers in Edinburgh have come under fire as new estimates suggest the cost of the dual-fuel powered newbuilds could reach £400m.

The figure for the CalMac ferries, does not include the millions pumped into the nationalised shipyard Ferguson Marine to keep it operating, amounts to over four times the £97m contract cost for the two lifeline ferries to serve on Arran on the Forth of Clyde.

Both newbuilds, Glen Sannox and the recently named twin, Glen Rosa following a public vote, still await delivery at the Inverclyde shipyard, downriver of Glasgow.

Chief executive of Ferguson Marine, David Tydeman indicated that it will cost an extra £240 million to build the ferries on top of what was previously spent before the nationalisation of the shipyard took place in 2019.

As The Herald, which more on the story, reports that £83.25 million was spent on the ferries prior to the Scottish Government taking control of the shipyard firm with an additional £45 million on loan.
