As it got closer, it appeared the boat is being painted. It reminded me of Memorial Day weekend a couple of years ago when I got this one of the Vernon C. Smith, with what looked like primer or undercoat or whatever it's called on the pilothouse.
But as the Sam M. Fleming passed my shooting spot, I got a closer look and wondered if I was right that it was primer or undercoat or whatever on the rear.
In the end, I decided I didn't really care. I'll find out what it was soon enough, if I need to know.
