Needless to say the BBC Scotland report on this plays the whole thing down and makes no accusations at all: https://www.bbc.co.uk/news/articles/ckgpj13p5x1o

The Orcadian is less restrained, with:

Electric hydrofoil vessel to return to Belfast in latest blow to £15m project.

Just over a year since electric hydrofoil ferry, Zevi 1, arrived in Orkney, the vessel is now to return to Belfast in the latest delay to the £15 million project to cut maritime carbon emissions.

It has emerged this week that Zevi 1 will undergo a “system upgrade” at a facility in Belfast owned by its developers, Artemis Technologies.

It is unclear when the vessel will arrive back in Orkney — with the project partners now working to agree a “suitable timeline” once the upgrades are complete. It is just the latest delay to hit a project and vessel beset by issues since its arrival in May, 2025.

None of the above highlighted phrases appear in the BBC Scotland report which allows the manufacturer to claim:

Artemis Technologies chief executive officer Iain Percy told BBC Radio Orkney the boat needed a software upgrade and some technical modifications.

“The main thing we are doing is bringing the boat back to tune its alarm systems,” he said.

“If we compare it to a car, we all know what it’s like getting a low tyre pressure warning light.

“It’s nothing fundamental and the upgrade won’t take too long.”

Really? If it’s just like a low tyre pressure light warning of the kind I get if I go too fast over a speed bump, why is it being recalled? A member of staff in Orkney could reset that. It looks to be much more serious, a safety concern, if they recall it.
