Magooch. Your last post on the NC Expedition makes a lot of sense - it probably an excellent all-around boat for medium to larger paddlers. The problem is that you like your boat so much that no matter what characteristics someone else is looking for in a kayk, you seem to think that the Expedition or some other NC kayak is the answer. Mitch started with asking for suggestions on "Ideas for truly fast kayaks". I don't know what other critia Mitch has for a boat, but we know he is looking for fast and efficient at about 4.5 knots. Kayaks that are narrower than the Expedition are truly faster and more efficient.
Not long ago, another poster was looking for the lightest possible kayaks. Again, your answer was NC kayaks.
As the owner of a Little Wing, I mentioned Warren Liitle Wing kayaks in response to the two posters criteria of speed and light weight, but I was not so adamant that the Warren boats are the best for everyone. I even said to Mitch that "there are probably other kayaks better suited for your purposes." Why would I say that? Because I am trying to be honest and objective, while not even knowing Mitches' other criteria besides speed.
I can assure you that each of the Little Wings is among the fastest and lightest and most manuverable for its length, and the among the most stable for its width of any kayak ever manufactured. Why would I not recommend Little Wings to everyone? Warren achieves the extremely light weight by manufacturing their boats from a very thin carbon layup over a foam core. I have had my boat only about six months, but it has already accumulated many small dents in the hull, and I have not hit anything that I know of that would have caused any of the dents. They seem to appear for no reason. Becuase of my comments to Zac Warren, they switched to a stiffer foam core and will make future customers aware that heavier layups are available, which should prevent much of the denting. But, their kayaks will no doubt weigh more, and light weight is one of their main claims in their adveritisements. There is always a trade off.
