My condolences to this man's family.
I've been following this thread for a while now and while everyone seems to be saying a lot about not only having, but using a life jacket, or PFD etc and there is mention of the various types available, some of the legalities about some of them, and a mention of alcohol use, but there is also one thing I haven't seen mentioned, and it's a pretty simple concept. Not going out alone. I firmly believe that you should never be going out on the water alone, especially on any of the Great Lakes for exactly this reason no matter how experienced you are. Anything can happen, and it can happen to anyone. All accidents are preventable.
If you're out there alone and something does happen, you're at the mercy of the lake unless or until someone hears or sees you, and often times, these things happen fast before you can call for help and these lakes do not show mercy. These lakes are known killers and all of the lakes, but especially Erie, can turn on you very quickly. If you're alone and you go over, you aren't likely to catch your boat, especially when it's a less than flat lake.
While I understand that some people just prefer to go out alone for any number of reasons, from not wanting to have to deal with "rookies," to can't find anyone available to go with them, to just don't want to take others out with them to avoid all the BS they've experienced in the past, there is also a saying that says there is safety in numbers. There is some truth to that.
Using a PFD, engine kill chords, not mixing alcohol with boating etc that's all great, but even an engine kill chord isn't going to necessarily save your life if you can't catch up to your boat that is drifting now and way over there and you're still where it was before you went over.
It seems to me, not going out alone is also a very wise preventative measure that should be given a great deal more consideration than it's being given, even by some of the most experienced members, because even if the person with you isn't an experienced boater, if you aren't out there alone, at the very least the other person with you can, or should be able to get that boat turned around to come get you and that could potentially save your life and tragedies such as this might not happen.
We don't know what happened in this incident. What we do know is a man went out fishing alone. A friend checked on him using a telescope less than an hour later (as reported) and realized he wasn't in the boat and called 911. We don't know how or why he ended up in the lake. There has been no mention in any of the public reporting that I have seen, as to whether he did or did not have on a life jacket or other PFD. There was no mention of whether he had or had not consumed any alcohol.
There are many potential lessons to be learned through this man's tragedy, and not going out alone might be one of those lessons. How many of us will learn it, but more importantly, how many of us will ignore that lesson and continue going out alone because of a mindset that says, "it's better to go alone than have to deal with a "rookie" or the BS I've experienced in the past"
While we can all speculate on why it happened, in the bigger picture all that matters is, he went out alone, and for whatever reason, he ended up in the lake, and it did not have a happy ending. THAT is what happened. Let's focus on that instead of focusing on speculation and theories about why it may have happened.
