I know exactly what you're talking about. I'm new myself and at first I found white water boats impossible to not just spin around on me after a few paddles. White water boats are just prone to spin and really reflect technique issues like a rec boat can't/won't. Some things that really helped me were to make sure I analyzed wrist roll to ensures the paddle was actually pulling flat through the water and not introducing spin. I have found this will vary depending upon the paddle bend, but typically I rotate my right wrist forward like rolling off the throttle on a motorcycle, and even more than that I can roll extra forward to change the nature of the right sided stroke to rotate me right a bit, should I be trying to spin pretty far to the right.
Anyways, it just comes with some time. Farting around on a lake and getting your stroke down helps... at least it has helped me
