Very sad, there definitely should be more consequences to the charter operator (I won't call him a captain because he is NOT!). The people that did the charter, probably had no idea it was illegal nor did they even know there was such a thing, ashame they did not know to ask a couple of questions - license? Insurance? -- but through their ignorance of how marine charts should work, put themselves in grave danger with a tragic outcome.
I am not a proponent of more government/regulation, but the world of boat charters/rentals is out of control. Even on LKN, the number of charters - some legal some not - that clog up the public boat ramps is ridiculous. Seeing an old clapped out SeaRay with a stereo that will shake your fillings out, the smell of weed wafting from it and tweakers on the bow just gives boating a bad look. Then there are the rentals, mostly pontoons that cluelessly amble all around the lake with no idea how to operate a boat on a busy waterway. Every summer there are multiple accidents involving these operations. The marina where I keep my boat shutdown is rental fleet - too much trouble and he is a smart guy and realized it was just a matter of time before his name and business was associated with a terrible accident.
Thankfully LKN is big enough I can avoid all this for the most part. I don't see this stuff every time I am out, but there are times. Post labor day is the best boating on LKN!
