Thanks Magnus, I am new to forums about sailing and your quite right. The Blue Water Cruising Association would be an excellent choice. Thanks for that.
I was on the east coast (Rhode Island) last summer and was astonished at how every harbour seems to be chock-a-block full of mooring buoys. It just seems to be the way the world is going. Once the harbours are full of buoys and floathomes, I guess us boaties will be anchoring outside in the swells...
Unlike say the Chesapeake or the Pacific Northwest, in east coast New England, viable anchorages are a scarcity. Typically, a good harbour with a well designed mooring field can accommodate many times the number of boats that would be able to safely anchor there. So in what comparatively few good harbours there are, the use of moorings is actually very beneficial for boaters.
True, most of those moorings are occupied by local boats, but a quick call to the harbourmaster will get you directed to one of the moorings available for transients (whether it is a dedicated transient mooring or one temporarily vacated by a local). Except in some very select harbours (Marblehead, for instance) on holiday weekends, it's rare to get turned away.
But the problem of "float homes" is a new one to me and seems like a different animal altogether. I think you make a good argument against them. I am trying to imagine what the reaction would be here in the Chesapeake region if folks started doing that. I'm pretty sure it would be negative.
In certain sections of the east coast, notably along the Intracoastal Waterway, certain local jurisdictions have had to deal with a similar problem: derelict, abandoned, or otherwise "permanently anchored" boats of all description. Many have implemented local laws that limit the number of days a boat can visit or remain in local waters.
That may be a solution for your area, but beware that it slices both ways. There has been a fairly vocal backlash from cruising sailors to such restrictions along the east coast.
