Perhaps the SLPA may have an impact on this type of construction on Winni, but perhaps with enough shoreline footage and sufficient shoreline deep water, this could be built here. I am currently looking into building something that size off the back of my house over the stream that runs there, so I can have my 19 FTer, my red toy tugboat, and my yellow ducky there.
Looking at the boats stored in there, I doubt that the other reason would not apply. We certainly have a large number of restored speedboats on Winni and other area lakes. Doesn't seem to be a deterrent to them.
Perhaps if one of us buys a new Four Winns, we could get a bus and go out there for a tour!
Hey, just like the Lottery...you can always dream.
