If you don't enjoy a boating community like Havi, dig a whole in your back yard and fill it with water. Boat there. You will not have to be bothered by folks you deem undesireable there.
Well, one of my back yards is Havi ... and I seem to find a LOT of undesirables there. So, in giving the advice back, they should dig a hole in their back yard and invite friends over and party on!
