Uncle Pug:This wasn't meant to be a thread about private property rights per se but rather about assessing what is known of the accident to see what steps could have been taken to change the outcome.
Well, I'm not sure what the article meant by "carrying their equipment". Were they wearing it?
Several things come to mind...
OW 101 maintain pos buoyancy at the surface.
I've seen divers take their gear off in the water and carry it down the beach. I leave mine on my back. It's easier to carry and you can still use it if you need to. If you fall in...breath off your reg...big deal!
If hiting the tides and navigating back to a small target of an exit is required you need to be able to plan for it and do it. If you can't maybe it's best to pass on the site. Covering less ground (staying closer to the exit) during the dive might help while you learn.
