Not Whaler related, but you don't actually get to witness this every day; unless, of course, you don't know how to handle your boat.

That guy has no business driving this 38 ft boat, To much power with no brains, He was going to fast and hit waves at the wrong angle, then slammed it to netural...Idiot...

There's a slow-motion version of the video referenced at the above link.
If you watch the throttles, he goes to full throttle, neutral, full reverse, and then ends up with the port and starboard engines at full reverse and the center engine at full throttle.

The slow-motion version is hard to watch--too many people go flying around the cockpit and land on their faces.

Dave -
Watching the throttles, he's only operating the two outside throttles the whole time.
...which begs the question: is he using the "shadow control mode" on DTS throttles?
That feature was introduced in 2008:

quote:
In triple engine set ups, the center engine is run by "shadow control." If the port and starboard engine are in the same gear, the center engine joins them and runs at the average speed of the other two. If the port and starboard engines are in different gears, the center engine goes to neutral.

I got the impression that his efforts with the controls produced no response from the engines. While I have to agree he is endangering himself and his passengers.

"Video by our own news crew..." More News Twits. They must have been shooting themselves for posterior-ity.
"Cool" Costs. I doubt the boat damage equals the hospital costs, but from the little I know, there has to be some.
Just getting the bite marks out of the interior will cost a lot. Q Ball sailed all the way across the boat to land, how?

If youtube was around when I was growing up, there's no way my mother would have let me ride in any cool boats.
Just sayin'.

Ya never know - thanks for the thread, show'd it to a few rowdies around here this morning and will same for others who think I should give them keys to my Whalers - ain't happening.

If it is I find it interesting that the throttles are left hand controlled.

Hope it was minor injuries. I'll bet the girl on the starboard side really didn't expect to have a snoot full of water hitting her square on though...

Re the controls: I think the two taller and outboard control handles are the throttles, and the shorter inboard controls are the F-N-R shift.

A-propos of nothing, fighter jets are laid out that way, as well as some go-fast boats in California, (steering wheel on the left like a car).
Of course, a lot of fast boats have a foot throttle too, the better for keeping both hands on the wheel. My 60+ mph Hydrostream Viper has a foot throttle.

6992WHALER posted 09-02-2012 12:57 PM ET (US)
Are there 3 or 4 controls?
If there are only three I don't think the middle one is the shift lever, unless it has some way to control each engine independently.

Looks like at the end one of the girls gets thrown into the throttles and bends them over. That had to hurt.
Is the driver actually moving the throttles to control the boat or his he using them as a handle and they are just moving with him? If he is deliberately moving the throttles I don't understand the reason to pump the throttles like he does.
kwik_wurk posted 09-02-2012 02:23 PM ET (US)
That's what a car accident looks like when you don't wear your seat belt. Hope everyone made out in one piece.
Not sure what happened, but throttle movements were a little fast and dramatic. People like this scare me, especially at night.
K Albus posted 09-02-2012 02:36 PM ET (US)
When running a high performance boat at high speeds, the throttle man will typically pull back on the throttles when he believes the boat is about to leave the water, for instance when jumping a wake or a wave. This is done to prevent the motor from over-revving.
It looks to me like the boat in the video was jumping a wake or a wave and stuffed the bow. The driver was working the throttles, but then lost control.
jimh posted 09-02-2012 03:07 PM ET (US)
I presume there are four handles on the shift-throttle controls. There are two taller handles for throttle control. There are two short handles for shift controls. The shorter handles are in FWD during the recording, as far as I can see. The driver works the taller handles to control the throttles. Pulling all the way back on the throttles just cuts the engine speed; it does not shift into reverse.
David Pendleton posted 09-02-2012 05:25 PM ET (US)
I have no experience with multi-engine boats and certainly not with those controls.
When I encounter a wake that I don't want to negotiate at speed, I slowly throttle back to near idle speed. I do this well in advance of the wake and let it roll under me.
My boat is heavy and comes down off plane very quickly (dragging two large, stationary props behind me probably contributes to this). I'm also travelling at ~28mph rather than ~60mph.
Of course, we don't know what the wake/wave looked like or at what angle he approached it. We are also unaware of how fast he was going or what his experience level with that boat was.
Whatever the conditions were, this trip ended badly, and that guy needs training before he kills someone.
jimp posted 09-02-2012 07:37 PM ET (US)
A few years ago while visiting my Dad on Long Island, NY I was talking to the guy in the slip next to Dad who had a 30' or so go-fast that could hit 65 mph. I asked him his boating experience and what other boats he'd had. The answer? "Grew up out here and this is my first boat ever." That scares me.
jimh posted 09-06-2012 09:39 AM ET (US)
The boating accident shown in the video (linked above) was investigated by one of the daily television chatty celebrity news shows. The show tracked down the passenger whose camera recorded the accident and interviewed him. He is the guy seen standing in the rear of the boat with a blue tee-shirt.
The boat was operated on Lake of the Ozarks. A short recording made that same day of the lake taken from another boat was shown, and the lake was full of boats and criss-crossing boat wakes--your typical holiday boating madhouse on a densely populated resort lake.
The two women in bathing suits in the front of the boat are mother and daughter. The daughter (in the purple bathing suit) has a fractured orbital socket as a result of her fall. The boat driver was apparently either dazed or unconscious after his fall, as he was still not in camera view in a portion of the recording made after the impact with the waves.

According to this new article
http:/ / www. news-leader. com/ viewint/ article/ 20120905/ LIFE06/ 3090 50095/ Video-captures-boat-s-violent-wake-crash-at-Lake-of-Ozarks-missou ri?odyssey=tab%7Ctopnews%7Ctext%7CFRONTPAGE
the cameraman is named Brett Tintera and was working for a cable television show, recording boating activities on the lake. He sustained a broken leg, broken wrist, and ruptured disc in his back as a result of the accident. He also says the boat speed at the time of the accident was 100-MPH.

I just have to say the guy is a complete imbicile for going that fast with unseated passengers. I am sure the engines have more intelligence then him.
