This is the Kahuna model of the famous Feathercraft line of collapsible kayaks. It is 15 ft long, weighs about 35 lbs, has a heavy duty neoprene bottom and stores in a large backpack, so it is easy to transport. We used it while cruising on our sailboat and would set it up in an anchorage and kayak around. It has a nice upswept bow and is a great kayak to paddle. It has inflatable sponsons for extra stability, plus it can carry a load if you are cruising in the kayak.
It is in very good shape with only one small 1" patch in the neoprene near the bow that I fixed years ago and covered with duct tape. I removed the tape to take a photo of the patch. It has not ever leaked. The kayak comes complete with carrying pack, sea sock, sprayskirt, paddle, and repair kit, all the stuff that came with it when it was new.
For more info, go to the Feathercraft website where specifications and videos of the assembly are available.
I put it together today and the pictures of it are on this site. For the buyer, I'll dissemble and reassemble it. It usually goes together in 30 minutes or so and the more you do it the faster it goes.
