"motorized" I believe is the key word. At any rate, one week ago North beach was recommended to me by a very nice lady pretty high up in the local heirarchy. I promised her I would use it and see what happens.

Wanna get together Sunday? 10:00 or so?

That site was home to the Edison Pageant of Light Regatta for many years. Eventually, the regatta ended, people stopped using the beach and a fence was erected. I asked the County to leave a gap in the fence for catamaran and other small boat use and they did. That must have been 10 or 15 years ago.

To my knowledge that beach has never been closed by statute, though the current residents are not particularly friendly to catamarans.
