Handling: I love the secondary stability of it. We've both taken it out on Puget Sound quite a bit in moderate chop and have never felt like we were going for a swim.
Tracks remarkably well for a 15 footer, especially when you get it up to speed. Not perfect, but once again, it's a 15 footer. Turns on a dime - very easy to control. When you have the rudder down, it's straight as an arrow.
Speed: I average 3.3 knots when casually paddling in calm water, she averages 2.8. When bringing it up to a sprint, I average around 4.8.
Definitely not as fast as our other kayak (Necky Looksha 17) but still cuts through the water much better than the other kayaks we tried first (Necky Eliza and Eskia).
All in all, a solid kayak for the kayaker on the small-intermediate size. You definitely feel the control with it - one of our advanced friends was having a field day with it in the wind chop on Lake Union.
The cockpit is a little constraining and I may remove the thigh braces to give me more leg motion. My boat is several years old and has no seat as such, only a foam pad and a backband. The newer boats have a thermoplastic seat which has to be a great improvement.
I recommend that any smaller person looking for a light weight kayak test paddle a Tornak. (I don't know where you will be able to do this, however, if other dealers have the same policy as Canoesport, our Houston Necky dealer. They will not let anyone test any of their boats even if you put a significant amount of money down and/or have purchased several thousand dollars worth of boats from them over the years.)
