They are not bad .the mussels do not attach to the bottom . I have my bottom with barrier coat and bottom paint have not had to do anything but power wash it. I do have a few on the out drive but they easily wash off I don't think they are worse here than anyplace else on the lake.
Pkr 314 is a friend of mine and what he said is all true also..
THE Bigest thing if I were you to consider is if you move to Meinke West it is a additional 45 minute drive each way to your boat. Would that influence and how much you would use it....for me it is only 7 miles from home .
I am on G slip they have 30 ' between docks and can easily handle boats to 40 ' long . Water and electric at the dock.
I wish you well with your decision. What ever you choose the next few years are going to be great with the recent large perch and walleye hatches
