Went down to plug the hole in my boat, the one that's left when the CF prod is taken home for winter. I had forgotten I'd left it open, in one of those "oh sh*t" 3 a.m. moments. But man, was the tide low, and I love going out when the water clears up this time of year and the water is super-shallow. You get to see where the deeper spots are and where the shoals have moved.
At the dock, it was so shallow I could see off bottom off my stern and what looked one heckuva lot like an inspection port cap that I'd dropped in the water months ago. So I felt around with a boat hook thinking I could lift it off the bottom and grab it. Guess what looks EXACTLY like an overboard inspection port in 3 feet of water....hint: they have tentacles and they sting. I think these are dead and sunken to the bottom.
