I sympathized even though it seemed like a very negative review until I got to your comment on Cozumel Island. That I had to laugh. I lived in Miami area for almost 20 years and now live on Cozumel for 15 year. I never saw water like we see here. Cozumel is a  scuba diver paradise with over 200 ft. visibility many days of the year. Comparing the water on Cozumel to the eastern coast, you must have just really have been having a bad day. We may have cool water a bit of the year but we mostly have warmer water than almost anywhere.
