There is one with non-functional engines that hangs on a mooring in Southwest Harbor every summer. Much cheaper than the "shantyboat" and since it is actually a boat, no one can complain about it being on a mooring. The only way they could get rid of it is to put in a requirement that the boat has to leave the mooring a minimum number of times during the season. That would be a real problem for some of the "display" boats kept on mooring in front of "summer homes", so it would never happen.
