Televisionary / Wised Up for Children's ITV, 2005
Two teams of 10-12-year-olds compete in a series of water-based challenges including kayaking, powerboating, surfing and so on, for a big holiday.
This was quite good actually, teaching about watersports while still looking, sounding and steering like a reality show.
It was boys v girls, in 10 episodes (the first 9 teaching sports then a big championhship in the 10th), and the boys won 7-6.
Watchable and enjoyable.
