While it appears (from a little research at the FL website) that what that officer said was technically accurate (about distance),there are a few paragraphs from the Florida law that would apply. It boils down to the same thing that the FAA can do to pilots, when all else doesn't cover your transgression, they go for "careless and reckless operation" which in FLorida boating law is a 1st degree misdemeanor ($100 and 60 days max I believe). Now the problem comes (apparently) in trying to get them out to you. BUT i'm thinking if you have witnesses, that maybe even a local cop could cite them. In any case, there is a law, it just isn't well-defined. http://www.boatsafe.com/Florida/index.htm
Here it is:Speed Limits and Reckless Operation:
Any vessel operating in a speed zone posted as "Idle Speed - No Wake" must operate at the minimum speed that will maintain steerageway.
Any vessel operating in a speed zone posted as "Slow Down - Minimum Wake" must operate fully off plane and completely settled in water. The vessel's wake must not be excessive nor create a hazard to other vessels.
Anyone who operates a vessel with a willful disregard for the safety of persons or property will be cited for reckless operation (a first-degree misdemeanor).
All operators are responsible for operating their vessel in a reasonable and prudent manner with regard for other vessel traffic, posted restrictions, in the presence of a diver-down flag, and other circumstances so as not to endanger other people or property. Failure to do so is considered careless operation.
A violation of the Federal Navigation Rules is also a violation of Florida law. Except in the event of an emergency, it is unlawful to moor or fasten to any lawfully placed navigation aid or regulatory marker.
