Sure, everybody screws up, sometimes BIG time
usually with their boats. Highest candidates are docking, anchoring and sail stuff. But "life threatening" is usually NOT an issue. Heck, when we started sailing our C22, I ended up losing the whole rudder tiller combo in very high winds because I put an ice chest underneath the tiller and it worked out of the pintles! Dumb - you bet. But I learned from that. I also learned to stop complaining about docking and practiced, practiced, practiced. How many of YOU do that?
I'm just waiting for the idiots who were out on the ice flow to start suing someone: the ice, G*d, the local county, you name it. Just plain stupid is way different than making mistakes.
They should be thankful for beign alive, and be thanking th folks who saved them. Emphasis on SAVE, not simply "helped us out."
