When we did the elbow in May it was no piece of cake. The winds were extremely high, the seas were extremely rough and the current was very swift.
The boat does back up to pick you up - 'cause you cannot swim to it, even if you wanted. The DMs said we would dive a couple of other spots and if anyone who was up to it (by their standards) would be allowed to do the Elbow. They had to put extra people in the water to help get divers on the boat.
IMHO this is another AOW dive (like Blue Hole), due to the current and wave action alone.
We had 3-people get sea sick at this site.
