AIRE has just produced a couple of new cataraft designs, marketed under the name "Wave Destroyer". The tubes have a dramatically upturned bow, and are clearly designed for heavy whitewater. The upturn is so the ends of the tubes don't become buried in an oncoming wave and squirt the boat out backwards, a problem that has plagued cats for years in whitewater.
Interesting concept. The Wave Destroyer is available in two lengths; 15' 6" and 14'. This boat will probably work very well with an outboard on rough water too, but the high bow is not really necessary for most float hunting situations in Alaska, except in heavy whitewater. Nice to see something different for a change.
