I’m cocomac, and I'll be running the photo contest for September.
The topic is "on the water", meaning anything that’s on the water, including (but not limited to) buoys, boats, wildlife, etc.
Standard rules apply (explicitly, it’s the same rules as the last photo contest).
Note that I was unfortunately unable to post this at the exact start time, so do not post photos until the start of September (UTC time). The contest ends at the end of September, and it will use UTC time.
This photo contest has concluded, congratulations to Tetsujin for winning! I've also archived this post (although I did also check the actual +/- scores).
