The only problem with a SketchUcruise is that Coen is prone to sea sickness if I remember correctly maybe there are others. But the Med in Spring / Autumn is quite calm and on a big ship this is not a major problem.
I DO think something could be organised along these lines and will work quietly way on it in the background.
The main thing is that there is a willingness by a good number of Members to have a Conference.
