Ok, I Need This. . . . . .

I'm also no expert, but a few comments:

Tracking and maneuverability are kind of opposite things. To maneuver you need to be able to spin around and one that tracks well resists quick turning. You can get the keel up out of the water by rolling up on edge and taking advantage of the curve (rocker) of the side of the boat and turn a lot faster (when you learn how).

If by white water, you mean rivers where you're scooting around boulders, a sea kayak won't do but you ought to be able to surf a little in saltwater waves with one. Be ready to get rolled over.

My strongest recommendation is to spend a few bucks and take a class or two from someone who knows their stuff. You can learn a bunch in a hurry and have fun doing it. A good shop should have lessons or know where to go.

It was really a rush to catch a wave. The guy in his shiny new boat in front of me, who didn't catch the wave, was a little annoyed when I ran over the top of him, but given his attitude, I thought it was a good experience for him to have.
