I recently purchased the K-Light Plus as a Demo boat from Piragis (it is a 2000 teal sealskin model). By the way, Steve Schon at Piragis is great to deal with.
The K-Light is a pure delight to paddle and is plenty fast enough to keep up with most other boats on the water. It is very light to carry and I had no problem putting it together in under 30 minutes right from the start. Its construction is very good and it appears as if it will last a life time. Obviously the portability of the K-Light is one of the primary reasons to purchase this boat and at just over 30 lbs it excels in this arena.
If you are looking for a light, easy to haul, relatively fast, well built folder look no further. At $2700 the price for a new K-Light is beyond my means but maybe you'll get lucky and find an excellent used one for much less.Outstanding boat if you can find one on the used market. Feathercraft has discontinued this model to produce larger boats. This is a shame because although it is only 13 feet long, it will keep up with a lot of longer boats. It is very stable, easy to turn and works well in the ocean, lakes or smooth rivers. The kayak can be set up in 15 minutes, but you should figure on about 30 minutes until you get the hang of some of the assembly techniques. If for some reason you find yourself swimming, the kayak can be reentered without a paddle float.
Kayak comes with a terrific backpack that will fit in the trunk of most cars. Hard to imagine a better foldable for the money. If you don't need a 17 foot foldable, this kayak will surprise you.
