I ride on the river dee Deeside Wakeboard & Waterski Club season hasn't really started yet but will in a couple of weeks. You have to join as a member (first few visits you don't need to join) and then find someone who is looking for extra crew (there is always someone looking) and just help towards the fuel, last year it was around £6 for a 10 minute run, I think it might go a bit higher this year because of cost of fuel etc.
