No, Gill. The one we went on was the Kapitan Bota, new this year. I understand from Jasna, our local TM, that the company (Katarina Lines) is gradually replacing their older boats. If you google Karatina Lines or Croatian Coastal Cruises (or something like that) you should find a list of their ships and by selecting "yours" you may find out what it looks like. That's what I did with K B and was very pleasantly surprised.
I did Canadian Rockies and Vancouver in 2013 (the RM wasn't an option then) and thoroughly enjoyed it. I've already booked for Canada and New England in the Fall (except that I'm going in June) next year, to make the pair.
Best wishes.
