G'Day Matt and Paddlewise,

To a very very rough approximation, not taking account of chaotic local
behaviour of paddled water, could slippage be measured either by repeatedly
moving a paddle in a tank or in a current free lake and having a floating
line with equispaced markers tightly stretched along the paddle route and
videoing the progress of the paddle relative to the markers? Possibly put a
set of colored rings along the shaft of the paddle where it enters the water
to help.

The test paddler might need a rudder to paddle in a sufficiently straight
line:~)

Expect this has been thought of and rejected for various reasons - but still
curious?

All the best, PeterO
