On the thread where the lady died in Islamorada, there are two issues no one has mentioned here.
1. What if the diver wears full-foot warm water fins? This is common in the Keys. As a matter of fact, they give you rental full-foot fins at most FLA dive ops. How would one hold onto them while climbing a rung-and-rail style ladder in pitching 5-6 foot seas such as in the fatality thread to which the original post is referring here?
2. The lady who died in Islamorada was reportedly diving from a boat moored in 5-6 foot seas with only one crew member, the Captain, on board when divers were in the water.
I certainly hope the crew/dive operator briefed the divers that should they drift away from the boat on the surface and need to be picked up (in the conditions) it could take upwards of 30 minutes or more. They reportedly recalled the rest of the divers first. She was in trouble from the moment she was finless. If no one is going to leap in to help you, you better hope you have all your gear and some air left in the tank.
I wouldn't want to be without fins for 15-30+ minutes in 5-6 foot seas. If only to help me stay on my back and keep my face out of the water.
