Well.....
Mainland to Arran...50 mins in good weather....May till Sept.
My daughter came back in wild weather....not even green.
We were diverted.once ...2 1/2 hours and to a different port. ...

....I was fine but had to be outside.
Normally it's absolutely fine ...really it is, I see a good few of the ferries everyday, they are big boats and there is not a problem.
