Yup your right about the tubes, they are the discontinued HD version.
The cat was made in 94, based of the serial#. It sat in the boat barn at the outfitter I used to work for in Maryland. One winter the owner told me to get all the crap outa the barn (lost and found, junk, ect), under a bunch of repair material I found original fs tubes and the frame against he wall. This being the east coast, no one knew enough to desire to take it home over the years. I spoke with the boss and he told me to enjoy my new "fly fishing boat" lol... cataraft girl showed me the way to rig it and ensured me that it was of whitewater quality here on the buzz.
I later had found, through a mutual friend, that the original owner had passed away after losing his fight with cancer, and that he would be thrilled to know his cat was still seeing use.
Last summer I caught some rebar (debris from an removed dam) in a real bad way on the savage river md, it sliced about a seven foot tear in my right tube and popped my bladder. I sent it back to Idaho for repair but it was to far gone (poorly cared for tubes, and another big old patch). I spoke with the shop manager about getting a single replacement but apparently thats not legal (coast guard requires matching serial #s). That when he said they had a purple 11ft in the demo fleet. Made in 2009, it is actually a prototype that they never bothered to put on the water. The pvc is inside-out, the thinner pvc coating is on the outside... he gave a awesome deal on em and the aire warranty!!!
I love my mini-cat
