Snorkel from Pier - Walking distance

[jdcml]

It has been a number of years since we have been to Cozumel. I seem to recall on our last stop we were able to essentially walk of the ship, turn left, and get in the water. We bought some fish food from a little shop that also rented gear. Do I have my ports mixed up? Does that still exist? The closest thing I could find using Google Maps was this picture below. We aren't looking for much, just enough to get the kids wet really.
