Re: We need a dang boat launch ettiquite lesson...
I decided, early on, that I would be a helper (if asked for) early.
I witnessed an amazing one.
Does anyone remember the Seventies? Well, it was jet boats, as the fastest on the lake(s). San's the super hyped up Evinrudes. The V-8's came a bit later.
Here's the story. (Factual)
Here I am sitting to pull my parents 1976 22' Starcraft Super Sport out of the landing. I was driving a 1973 Thunderbird (460 CID-C-6 trans, and a 9" rear, with traction control). I pulled many a broke boat out with that unit.

It was a truck with extremely luxurious appointments. Nice, in 1975.
We sit and we sit and we sit. A/C on, of course. My freinds-fast asleep. One freind, a qualified boater, "drowsing" -waiting. Our signal was two "toots" on the car horn and a headlight flash.
I went down to the ramp to watch the "action".
We'd been out on the lake, all day, we were exhausted.
There was a jet boat, sporting a 455 cid. Olds and a Berkley pump. He harasessed every boater, on the lake, spraying us with his "Jet Wash".
He got his.
When it was time for him to load his boat, on the trailer, we all watched.
He had his buddy back his trailer down, towed by a 1969 Chev. 396 HO Chevelle.
The guy drove the boat, on the trailer. The one thing they missed was the safety chain. The winch rope was attached but the winch was in "free wheel" mode. Another "forget".
Being what they were, the guy in the boat said "hit it". The guy in Chevelle did so, leaving a spectacular burn out and pulled him up.
You can see where this is going.
The winch handle went supersonic and the boat stayed. The car/trailer-did not. The winch went to it's rope limit and unloaded the trailer, of it's intended boat.
The guy, in the Chevelle, kept pulling, about 100' up the ramp. No boat, just trailer and a boat tied to it. About 50' up the ramp. They realized what was happening-not good. That was one damn good rope. I can't believe, to this day, it held.
Nobody helped, many clapped.
I did, help the guy get his boat, on the trailer. He was, as we say: "Spanked".
The damage was spectacular. The jet pump intake was-gone and the fiberglass damage put it into the "Boat Rebuilding" category.
I never saw him again, at that lake. "Spanked", I think he knew.
I did help him. We are, "boaters", by the way.
Help those that you can. If they deny, that's their problem, not yours.
