Oh wow Propeller you've really kind of stretched your imagination here! I don't supppose you could close all public/private boat launches but in theory you could allow only a certain number of boats in the water from these launches on any given day. (this issue has been discussed on the forum before actually) I can't imagine telling marina's to get rid of existing boat slips however in theory i guess some sort of legislation could be passed that allows only a certain number of dry docks per marina. Lastly I can't imagine ever telling private lakefront owners they can't have the priviledge of having a boat, although we do have a certain amount of dock space pertaining to the amount of frontage we have so I guess that part is already legislated. Mmmmmmmmmm.
