Most people seem to agree that some beach cats are capable of short bursts of speed above 24 knots (or is it mph?), as when surfing a wave or when a big gust hits right before the pitchpole. The argument seems to be about whether they are capable of sustaining such speeds over a given distance or certain number of minutes.

Therefore, the people who do not believe it is possible to sustain higher speeds for more than a few seconds are not going to be swayed by one radar gun reading giving the speed for one instant in time.
