I help them. Every time. I might only get to help a couple a day while I am launching and retrieving, but I always lend a hand or give some advice to folks who are struggling...
I have never understood the mentality of a heckler, and honestly, when I see people doing it that I know, I think less of them for it.
Some of the folks on here have gotten down and lent a hand that I know of, but they are the minority. Mostly, it is taking pictures of someone elses misfortune.
If that energy was spent being part of the solution, we would have a lot more good boaters out there.
