Yes, with a group of Morgans.
It was (IIRC) my suggestion that we used that route.
It was indeed, and a jolly excellent suggestion it was too!
It's a lovely little ferry, room for just 6 cars at a time
The turntable means it's very easy to use, you drive on and when you arrive at the other side they turn the turntable so you drive off forwards too
The water was very calm when we crossed, so it was great fun.
