It was surprising to me that there were so many people in the water. Things looked reasonably calm once you got past the surf, but just a couple hours after the fatality we saw several open water classes going in. They were each at a 4:1 ratio, which suddenly doesn't seem so great when you're talking about people who have never done a surf entry before.
The gentleman who died was quite large, I'm sure that is a risk factor when you add in all the gear plus the extra weight needed for neutral buoyancy. It's not always possible but my personal goal is to train more vigorously than the actual event, so that when things go sideways there's a bit of margin. PADI makes it seem like moderate fitness is fine for most types of diving, and I just don't think that's true.
