I owned a Riot Disco for over two years and used it in virually all water conditions. I was quite fortunate because my particular boat came with the Surf Seat as opposed to any of the earlier devices seats which tended to make the kayak far too heavy.
The Disco has to be one of the all time classic kayaks. A kayak that has changed the way in which the industry designs new kayaks. The Disco was probably the first short PnP kayak that could actually perform.
