The K-Pak is a polyurethane fabric boat that achieves rigidity through an aluminum frame and inflatable tubes that run the length of the vessel. The boat runs 9'3" long and sits 30" wide when ready to paddle. On the water, the boat is nimble and relatively fast. I was able to maintain 2.5 mph on flat water with ease (despite the presence of a stiff wind).
The K-Pak weighs a mere 21 pounds and folds into a compact package. It fits nicely into the back of our campervan while leaving ample room for the rest of the gear we usually carry. The simple design also allows for a set up/break down time of 5 mins. That was the big selling factor for us.
Assembly and dis-assembly take about 5 minutes start to finish. We would see a spot off the highway, park, assemble and launch in no time. We would visit three different places a day with ease allowing us to fish more places and see more things than had we done it any other way. It really made out vacation and now we are using them all over.
