Just got wind of this, apparently this a new law that went into effect this month, called the Boater Freedom Act, for the State of KY.


SB 66: Known as the "Boater Freedom Act," this law will require boating enforcement officers to have a reasonable suspicion of violation of the state's boating laws before boarding and inspecting a boat on state waterways.

Sounds good to me! the 4th amendment applies everywhere.
