Review So I have been paddling since I was old enough to hold one. I started in a canoe and ran my first whitewater at age seven. Fell in LOVE. I bought my first play boat when I was 14. I bought a s/m 4-20 last week and spent about 18 hrs on the river over the weekend. I started in flat water and loved it from the start. Cartwheels like a dream. From there moved to the falls of the James, class II-IV. What can I say? I absolutely love this boat. To be honest I'm pissed off that I have a job and can't be in it all day everyday. I was worried that it would get swallowed up in big water due to its size but its design allows for a lot of volume and a shit load of control. Conclusion I love this boat. So comfy i could sleep in it. Buy one.
