The keel of my old, Old Town Loon kayak is pretty flat, so the boat sways markedly from side to side. I use it on mountain lakes and quiet rivers, where tracking matters more than quick turns.
To improve tracking, I might jerry-rig a keel by duct-taping a strip of wood or plastic molding to the hull. I might blow-dry the tape to soften and set it.
Am I misguided? Or might such a keel last a while? A taped keel would, at least, put no drill holes in the bottom of my boat. And if it didn't help, might I peel it all off and clean up with Goo Gone and Dawn dish detergent?
Alternatively, I might add a skeg or keel. My other kayak came with a foot-operated rudder. It tracks like an arrow and turns smooth as butter. I LOVE it. Would it be feasible and harmless to add a retractable rudder with foot pedals to the Loon?
