Good news indeed! A valuable lesson learned, I'm sure...
I'm guessing most people don't realize that if ill-prepared, and fully geared, you're not going to be swimming as if in swimming shorts. The boots drastically affect your ability to swim (most that I've seen don't use any type of fins) and most (that I've seen) aren't going long distances. They simply want to get to a rock a little further out. If he was on the rock I'm thinking of, at the right stage, that currents' taking you for a ride. I've found myself semi-floating around thinking I was making progress in getting to shore when in fact, I was simply moving parallel with the shore due to the current, having to use my rod as a staff...to simply catch my breath. When you think it out before-hand, you think you'll know what to do AND do it....ie: drop gear, remove unnecessary weight that's affecting your ability to swim, whatever the circumstance...you've thought about it and how you'd react. However, as the #^&#^&#^&#^&z hitting the fan (we don't actually realize it and we aren't about to drop a $1K setup in the drink> because we know we can make it.
I think too many people unfamiliar with the many conditions that the ocean can quickly bring upon us are hopping into wetsuits and taking things for granted. I'm not saying that's what this person did....just sayin' is all.
I have a strange feeling that we'll be seeing more and more of these types of incidents. Hopefully, they all turn out as this one did.
