Fat Jack... What Marine systems are you talking about? Who is the makes it? Model? Etc? Proven where? Where is your data? Post the websites for all to research?
A handheld radar gun has all of the drawbacks listed. Now if you want to discuss a radar that will work for speed enforcement on the water, you need to be able to cite the target vessel's actual course and speed relative to your position, course and speed. To do that you need an expensive radar that has target designation (to isolate the offending vessel and give the range to the offending vessel) as well as plot speed and course. The Sigma-6 radar from Rutter does this, but its expensive and requires a dedicated officer (RIO - Radar Intercept Officer) to operate.
A Court would recognize an expert officers estimation, especially when the vehicle was traveling in a STRAIGHT line relative to the officers position or vehicle. Police cars also have calibrated speedometers that are acceptable in a court of law. If the law enforcement officer does not know my course and bearing or distance relative to his position he cannot accurately estimate speed.... its SIMPLE geometry. Straight Line is the key to the equation.
Gilligan, the RIB's used by the Mp's on Winni can catch just about any boat on the lake.... they are pretty fast, 60+ or so
