I'll be interested in what you hear. I was on the Cuan almost 20 years ago and enjoyed our time. Not a real dive dedicated boat but a nice balance if many non divers in your group or you are happy with two dives a day. Lots of average dive sites and a few really good ones. Highlight for me was the Rhone as a night dive. Good crew and exceptional facilities for a live aboard. It will be interesting to hear what recent guests have to say.
