I'm open to that sort of thing. AFAIK I am free during the tall ships - but people tend not to let me know stuff like that until the last minute!
From what I can see of other cruise threads when you try to organise it by committee, as with most things in life, it never really happens. Far better to post a thread saying "SMALLER BOATS CRUISE ROUND XYZ on 00th of ABC - ALL WELCOME" and then people will either "sign up" or not.
I will be out fro the tallships weekend, unfortunately I have somehow ended up with my mother in law on the boat, I'm hoping to lose her at some point over the side.
