We too sail out of Muskegon on the western shore of Lake Michigan. I will say that over the last two years there have been days when the CG does safety
checks of pretty much all or as many as they can stop vessels leaving the channel. I've also seen the Sheriff pull over many boats. Again like most other observations it has mostly been runabouts and power boats for the sheriff. Not that I'm condoning the action but that is usually the folks that are getting drunk and running into stuff. The Coasties I would say are pretty indescriminate in their inspections.
That being said it seems that at least 1 power boat
a year manages to run into the outer breakwater arms in Muskegon or other ports
in the area. It happens when as so many power boaters do they are affraid to go more than 100yrd offshore
and when they come up the shorline they will inevitably see the inner lighthouse directly ahead. All the meanwhile never turning their neck to see the OUTTER LIGHTHOUSE! It's gotten so bad they had to put a bunch of lights strung along the breakwalls....
