I'm really hoping it's something like progressive enhancement, but for ferries. It seems like a similar problem to web development. If you rely on JavaScript of even the most basic features, you risk having everything break, when you make a mistake in a tiny bit of JS somewhere. There may be limits to what you can do with a modern ferry, but it would be nice that if when everything else fails, it just revert back to being a "dumb ferry". So you'd be able to use it, but only in fair weather, or with more staff, something like that. Then you yank out the broken bit and install a replacement. While knowing very little about ferries, I suspect it's the integration of systems that makes repairs difficult.
