Dave, Seriously (as serious as one with absolutely no formal knowledge of the subject can get), I suspect your kayak has more than one resonant frequency ..., rather like the body of a stringed instrument. Maybe you could draw a bow across the keel while pressing down at various points along the way and let us know the results. May I suggest "Row, row, row your boat" as a simple tune to begin with. It was the glue!
