We swam against the current on the descent and on mooring lines. They were very explicit about never releasing the line lest we get swept to the Bahamas. Apparently a woman had done this a day earlier. My only real complaint is that we paid for a 1:2 guide and due to the dive company’s screw up, we ended up 1:4. We needed the guide because we only have OW certs. The experience taught my wife and I how self-sufficient and knowledgeable divers need to be. It was cool. My local dive shop DM also suggested that my calmness at the depth and low air may have been due to a touch of the narcosis. I was proud of my composure. Now I know I was probably just too high to care.
