Looking north, this is an aerial view of Braun Bay:
That's Gilnes Island in the lower-right quadrant of the photo. The questioned area of Braun Bay is opposite—10-o'clock to the left. Hermit Cove is just behind (north of) Gilnes Island, with a rather indistinct Hermit Island nestled in it.
(Lettering—or something—appears to have been photoshopped from the lower right corner).
At present, all I have available is a Lake Winnipesaukee chart from 1987.
On it,
Duncan shows just two rafting zones on all of Lake Winnipesaukee!
(Wentworth Cove south of Governor's Island, and a large, west-facing shoreline on Long Island).
The probl...issue of rafting appears to have been generated within the last 20 years or so.

I still don't understand why
boaters in the area would comprise most of the complainants. Could
NH Fish & Game be a part of the complaints?
