Mentioned previously, and certainly worth a look, is Native Kayak's Ultimate. It's a hybrid...a cross between a sit in kayak and a canoe. Someone mentioned leaders in innovation and left this brand out. IMO Native belongs right there with Hobie. I can also attest to the comfort of the seat in this kayak: best in the business. The Ultimate 12 weighs about 55 pounds... yet there is a 12' Tegris version (lighter material) that runs about 36 pounds.
This is very stable. I own the 14.5, which on a calm lake (or on the flats in the Keys...where I rent them), is fairly easy to stand in for sight fishing or fly casting once you master the technique. One benefit of the design is that it can be paddled upstream more easily than many other kayaks. I use mine in the Kankakee, and find it is just about perfect. It tracks very well and is fast.
If you are so inclined, Native offers a Propel drive system for pedaling that significantly outperforms the Hobie and will go in reverse (the Hobie system won't). It is not as good in shallow water or heavy weeds. There the Hobie wins out.
I have not used my Ultimate on the Big Lake, however the Native web site shows a few fisherman in Milwaukee with some nice salmon landed from their Ultimates.
By the way, the Native Ultimate comes in a 9.5" size for smaller paddlers that weighs 39 pounds, yet I'm not sure of its maximum capacity. The 12" has a capacity of 350 pounds. The 14.5's capacity is 450 pounds (they offer a tandem version that can be converted to a solo), and the 16's capacity is 600 pounds (also a tandem). As this craft is an open hull for pretty much its entire length, it is fairly easy to load multiple rods within it.
As a brand, there are only two problems with Native:
1) They do not have any Illinois dealers. The closest to Northern Illinois is in Wisconsin unless you choose an Orvis shop (it's in their catalog).
2) They are not the least expensive option if price is your primary consideration.
I hope this helps.
