Looking to purchase either a cat or a raft to float the kenai and other rivers. Main purpose would be for flyfishing and just floating. I will not use it for hunting. The question would be pros and cons of each, what works better to fish 5ppl + rower? Is one easier to control than the other? I have been looking at some 16-18 used cats for sale on craigs list and alaskas list. Suggestions please!
