G'Day,

In a related thought could it be the activity of the water. I find that a
small degree of wave action makes it seem much easier to paddle than when in
flat water. Is this an illusion or in a slight chop is there less water in
contact with the hull at any instant? Perhaps the boat is tending to be
'thrown up out of the water due to a net upward movement of the waves?

Is this related to the phenomenon of reduced friction is water with surfaces
subject to vibration?

Should we consider playing music directly into the hulls of our boats to
make them go faster?

Or is it an illusion?

All the best, PeterO
