However the part that he posted does refer to smaller boats.
ie, if you are negligent in regards to your wake that can be a violation. WA state law also makes the same point.
Yes, I have read that as well, many times.
The challenge is defining negligent. The mere operation a boat at it's designed speed, in an uncontrolled area does not make for negligence. The mere operation of your boat at its designed speed, in the close proximity to other boats does not make for negligence.
If that were the case then the USCG would be issuing citations at the mouth of every harbor I've seen.
Thats why we have no wake and speed restricted zones on waterways.
The lack of such, implies the ability to operate a boat at its designed speed.
Now...Not keeping a sharp lookout, does make for negligence. We have a duty to keep a sharp lookout, and to be aware of our surroundings. We have a duty to keep our boats in a ship shape manner, making them safe if we experience the normal conditions at sea. This form of negligence is much easier to prove, in my opinion.
The cruxt is to try to find some case law that shows the USCG procecuting a recreational boater for driving his boat at its designed speed un a uncontrolled area. Try to find some caselaw where someone was sued and lost, in the federal court system.
You won't find many, if any. The ones you do find will be undoubtedly a situation where someone clearly showed negligence. Such as blazing through a no wake zone, or something other than just operating their boat up on plane.
We need to remember that it's not the exact words written into a law that are important. What is important is how the courts have ruled on various aspects of that law.
