I used to have a 9' and it depends on your experience. DO NOT risk it unless you know your boat and your water. Up to class III and some class IV water if you are VERY experienced. I stay away from level V or any water with lots of class IV with that size boat. Mine was getting very old and I wanted to get a new longer one to track better. What kind did you buy. I am still looking.
