Aw, you should all definitely go for it.
There'll be about ten people who are shit-hot and then everyone else will be pretty-much the same standard.
There'll probably be the odd person who brings a surf-board or an inflatable dinosaur - those guys might be laughed at, but you won't.
The two boats might be a pain, but you can deffo work something out. Perhaps ask Colm from 0-canoe can you demo a boat down there? Perhaps ask one of the locals can you borrow theirs.
Either way you should register for doing it and worry about the details later.
