Here is a quick summary of the dives.
The boat left the dock about 45 minutes late and we headed north out of Jupiter for our 2 hour ride up the the Rankin. When we got there conditions seemed perfect. Seas were flat about 1-2 feet, the water was blue and there was only a slight current. Once we hit the water and started to decend, we could not see the wreck. At about 90-100 feet visibility dropped to zero. I could have been 5 feet from the wreck but I have no idea. So much for diving the Rankin. So the captain took us south to the Hole in the Wall, which is a REALLY awesome dive. After that, we dove the 3 wrecks of the Zion, the Bonaire, and a third (can't remember it's name), and our final dive of the day was the tunnels. Overall I really enjoyed the last 3 sites and it made up for not seeing the Rankin.
BTW we only saw one shark and it was a nurse shark not a lemon.
