The winds on Winter Harbor yesterday weren't
all that bad; plus, modern
small sailboats have flotation to keep them from sinking out of sight.
Between the markers, the entrance to Winter Harbor is only about 20' deep: at Ice-Out, you can see features on the bottom. BUT...Winter Harbor's
entrance gets a full-blast of whatever's on the Broads.
In the middle of Winter Harbor, I did see a ~20-foot sailboat—
yellow and white—that should have turned back.
