how would your comparison of rowing an oar vs. pedaling a propeller change if one rowed a propeller? imagine and erg machine with the fan rotated 90 degrees and immersed in the water. seems to me you'd get the benefit of using more muscles combined with the benefit of using lift instead of drag for propulsion.
