About the reviewer kayaker from 1990 Test environment River from 4 to 5 level manoeuvrable Review I was always in love with the Inazone and as soon as I could, I bought the Z. One. Compared to the previous model, the stern is less flat, but it immediately becomes a habit. This season I used it on rivers of level 4 +. I find it very stable and above all fast breaks good holes and did not decompose, even the tail narrower than the old model is not taken and does not make enders involuntary. I am very satisfied. As defects : the support for feet is small and should be enlarged and the tip of the boat is breakable with the rock (like Inazone). Sorry for the english I have used Google translator. Conclusion Boat easy and stable
