You can't row strong until you row stable.

Every motion in a boat is either contributing to stable movement or eroding it. Until you are confident your boat will be flat and solid, your efforts at propulsion are diluted. I have some tricks for imposing stability into a platform that is second only to helicopters in dynamic chaos.

No amount of leaning can come close to the effect of the oars in stabilizing the boat, side-to-side. To prevent roll, you need to make sure what happens on one side of the boat at the end of those 288cm balancing poles balances the other. That means making sure they are squared in the oarlocks before you pull on them.
