We are wrapping up our 6th troube-free season of use with our Tandem Tomcat and have been very pleased with its performance. The Tomcat just completed a week-long trip on the Main Salmon piloted primarily by my 16 year old daughter and her 11 year old friend, and they ran every rapid but Big Mallard, including the new Alder Creek and Black Creek rapids. This boat can easily handle class III-IV water in the hands of the right 16 year old. The boat can also be rigged with one seat for solo paddling, and it has made several Rogue River trips this way. The multiple lash points allow dry bags and paco pads to be tied in easily. The boat can be pumped up very rigid, and even after 6 years it will still stay rigidly inflated until you let the air back out the valve. No leaks whatsovever. The valves have been bombproof too. Overall, this has been a great IK, and for the money it is really tough to beat.
