Yeah, Stomper is semi-planing, but I get the question. I would advise more Duffek strokes or similar hybrid draw strokes to keep your boat going where you want it to. Stay on top of the angle, paddle more aggressively. Esp playboats allow you to point the boat where you want to go in all of 1 stroke. Corrections take more time and effort in most creekboats.
I also tend to move my seat forward, esp if you have a fair bit of gear behind the seat it's useful. I don't think that's the root of your problem though. You're going to need to adjust your paddling technique.
