Nobody left to teach them, mostly.
My kids'll do it, not goos at it, but enjoy it, But lets be honest, today even our "family" boats have progressed into extreme MPH monsters.
Kinda why I keep the Charger around. Back in the day, when I was learning to ski, my Unc thought it was great if we "Nephews and Nieces" survived his roosts and 55 or so MPH in his Olds powered Sidewinder! (Unc is a COMPLETE motorhead. This was back in '77 or so and these things rarely did 50 MPH).
ONE TIME he was towing both his wife and daughter at Saguaro Lake, who kept giving the thumbs up for more speed, and he didn't have any more to give.
He sold the Sidewinder on Monday, bought a new Biesemeyer 18' hull by Friday, and had built a 500HP 454 for it by the following Friday.
He NEVER got a thumbs up again......ever........until the day he sold the boat in 1996...... His reasoning........ "Nobody will EVER ask me to go faster than I can"........
The ones into Jet Boats these days are all about 'Hitting 80+ MPH' , Wheelies and Roost. These youngin's forget what it's all about and why they exist in the first place.
Crewcheif is the exception to the rule, as am I. But we, and MRS Crewcheif, remember what the boats were built for and why.
