Thanks for the links. We're watching the activity in Grand Case harbor from the deck of our rental apartment and were curious about the larger yacht anchored there. I can't seem to Id it from the website, but it's probably user error! It's one that has the large door that opens at water level to let out a boat, and it's been sitting open.
It's been a busy morning with several of the anchored boats setting off, a provisioning truck delivering (we think), several dinghies coming in to pick up and drop off passengers, and a couple of groups of school kids down for water time in the roped off area. I thought it would be swimming lessons but it appeared to just be a time to frantically run in and out of the shallow water, with no real swimming instruction! They are big enough to be swimming so it's too bad it wasn't actually a swim class.
We also were assaulted with a very strong sewer smell. Thought it was coming in on the wind, but then later noticed that there was a small stream of liquid being pumped into the harbor from a few doors down. I suspect it means someone has emptied a septic?
