Load of gonads - PLA and Medway use knots, "knot" to mention others.
Be interesting to see where the norm settles with regard to prosecution for speeding, whatever the units of measurement.
Common sense has always recognised that real issue at river speeds is unacceptable wash - and no-one can agree on that either.
aye, there's the rub -
speed is absolute (once defined as over the land; over the water is more difficult to measure at any point in time)
Wash is more difficult being subjective, in the eye of the beholder and depends on bank / depth considerations
