And here is a video of vehicles disembarking just before we got on yesterday, at Claonaig:

You see the big vehicle ramp gradually lower to allow vehicles off. The boat just runs aground at the landing stage and probably uses light engine pressure to stay there. There's no tying up, or rope throwing, and you've got to be alert as it's surprising how quickly everyone's off/on and the boat's under way again.
