Kayak Paddle w/ Canoe

I used my 15 p.Marquette as a solo the other night and the canoe paddle made the thing track like driftwood… I am a big dude and I was just man handling the thing around… I am gonna go back out tonight with a 7.5ft kayak paddle set up. It makes sense in my head, but does anyone have any advice from experience? (I kneeled in the middle, much like a kayak)
