OK this will show how little I know about this right now ...

I watched a Liffey Descent 2003 video and I am intrigued. Plenty of hairy
capsizes to watch, but I've got no-one handy to ask who has actually been
there and done it!

My question is, is it OK to accept help from safety staff with getting lost
paddle back, or getting ashore or re-entry into the boat and to then
continue racing?

Or is it a case of 'a rescue swimmer so much as touches you and it's
curtains'?
