Lately I've been hearing a bit about posting a speed limit on Winnipesaukee. I'm sure many would agree and many others would disagree about this regulation, but my question is regarding speed enforcement. Does radar work on water? I thought that in order to get an accurate speed rating, the radar had to be on a flat surface, or at least on something steady. Not sure if those MP boats would qualify as "steady."

Maybe someone out there is a little more knowledgeable on this subject and could help me out...

Thanks!
