I have a small (26ft.), single engine express cruiser that will not (quite) reach the proposed 45 MPH speed limit, so I personally have no axe to grind in this matter.
However, with that said and for technical reasons, I do not believe that enforcement of the 45 MPH speed limit is as easy as some of you seeem to think because:
Fiberglass boats make poor radar targets at best; fiberglass does not reflect radar signals very well. This is why companies make and sell radar reflecters for ocean-going boats that are likely to need to operate in heavy fog!
So far as I'm aware, hand-held radar guns are intended to compare the speed of an on-coming target to a stationary position (the parked cruiser). I strongly suspect that the readings would be heavily effected by the relative speeds and courses of the MP boat and whatever they were targeting. Getting accurate readings would seem to require a much more sophisticated and expensive technology! (Perhaps Skip could weigh in on this?)
Unless we all start carrying some sort of transponder, the MP boat would need to be close enough to the offending boat to either read the bow numbers or chase it down.
Safe operating speed is determined by circumstances; absolute speed has nothing to do with it! There are plenty of situations in which my 43 MPH top end would constitute reckless operation. And, if an MP officer observes a boat being operated in an unsafe manner, he already has the legal basis to ticket the operator; no further laws are needed!
What's really needed on the lake are more common sense and courtesy, which are difficult to legislate. IMHO, this speed limit is nothing more than a thinly veiled attempt to drive performance boats off the lake!
