In NJ you need a license
to operate any motorized vessel, including PWC
As of June 2008 a boating safety
class is mandatory...no more test-out options.
We actually have two licenses...one for tidal waters and one for lakes and non tidal rivers. The non-tidal license appears as an endorsement on your drivers license.
The tidal license is a separate license.
Any violations on the water
or visa versa, can affect your drivers license.
In other words, they can suspend your auto drivers license for DUI on the water
I believe miost states in the USA have some form regulation today as I see the textbooks online when I purchase
