Things are different on Lake Michigan. A bad season last summer due to COVID travel restrictions and extremely high water hurt everyone, marina owners and boaters alike.
One State owned marina offered a substantial discount for the first two months due to electrical and other high water problems. Many marinas experienced increased cost factors related to the extremely high water levels. Some did a good job of fighting the "tide". Some, (like mine) not so much.
As things stand right now I don't expect to see cost increases. If the owner of my marina raises the rates, even a nickel, I'm gone. I am very tired of flooded parking areas, mud everywhere, half assed stop gap measures to stay above the flood (pallets to jump from and toward to get to the dock, etc.)
I sure would not want to own a marina on Lake Michigan these days but I'm not in the mood to bail mine out.
