. If your inland not many will pay any attention unless your doing something stupid
Exactly
Only seen in 'enforced' once in 40 years. This is on an larger inland lake (NY) with regular waterborne sheriff patrols.
Neighbor bought a new to him wake boat out of state and had obviously the wrong numbers on the boat still.
Late teens early 20's kids in family take the wake boat out with a couple on following on a jet ski - and are surfing after sundown... Legally not supposed to ski board or surf after sundown even though it is still bright out.
When sheriffs boat rolls up the two on the ski take off because one of them isn't wearing a jacket. This was pretty dumb as most folks including the sheriff know what boat/ski belongs to what cottage... Sheriff pulls over the boat of course numbers do not match the registration.
Officer handled it the right way, he stopped by the next morning spend some time speaking to the adults in the house about expectations for safety etc. Was good he was more focused on driving the right behavior than writing tickets, gave him a day or two to get the correct numbers on his boat...
Personally one of my numbers is missing a letter or digit as I was too stupid to leave enough room between the first letter and my registration sticker... never has come up so yes enforcement is completely variable and more behavior dependent
