Myth - busted

Alton Mumma · 04-24-2007, 10:10 PM

I agree, this one needs to be revisited, in the water.

In the small scale, they were able to split one scale boat. They had no success when they pulled the small scale boats into the piling, but when one of them simply grabbed onto a boat and slammed it into the piling, it spit. Because he had a hold on it, it didn't bounce off like all the other boats. If you factor water into the large scale tests I bet the results would change.

Other views back at the marina:

It was "Temporary Insanity's" skipper who claimed a 25-MPH impact speed. "Build-Team" attempted to refute that.

The "Discovery Community" website isn't happy with this test, either: "Bad, Build-Team, BAD!"

Quote:

"They have also excluded loading.
No motor, no gear, no passengers...
all the factors that would serve to drive the boat onto the post were omitted from the test.

I also disagree with their estimate of the impact point.
It's almost dead on the nose and not from the side.

Once again, the Build Team over simplifies and under tests."

It's funny that they dropped the boat at the end and the bow area was really demolished. IIRC, the boat only dropped about 30 to 40 feet and therefore could not have been going more than 20-25 MPH when it hit the ground. If hitting a blunt surface at 25 MPH (with no engines attached) could do that much damage, it's quite possible that a point load at the same speed could cut into the boat as deeply as it did, especially if the boat in question was built differently (and had engines). They were way off base on that one.

I say we conduct our own test...I'll pay for the steel piling and all the beer we can drink while we watch the test. Only one catch: We are going to conduct the test with the boats that cause way more damage and are far more dangerous than go-fast boats. Care to guess what kind of boats these are?

Hey SP,that's my new 10 person PWC.Back off or I'll beach that thing next to the T-bar!

Have at it SS... While you're at it bring the dancing girls too!

I posted a picture in photopost of the same boat. I don't remember where on the web I found the picture, but it seems to prove the first picture.

This is reported to be the same boat at haul out.

To me, the original picture looks like a smaller boat than the boat in these two pictures. But it could just be the angle or lens.

What myth did they bust? That the accident occured? Or that the speed of the accident was only 25MPH?

It does seem like a look of damage for 25MPH. Something about these pictures just doesn't look right. I suspect staging.

I haven't seen the show yet so take what I say with a grain of salt. But I would suspect the test would be a lot different with the weight of the engines and fuel (which could add up to 3000# to the test). Also I would suspect that the original collision occurred with the engines running and producing substantial power. That boat at 25 mph would be just up on plane, requiring much power to keep it moving. Obviously the collision was unintended and the operator, even if he was at the controls after hitting, would take a second or two to throttle down. I would think the force from the engines would be enough to cause more damage than just a coasting boat hitting the pier. Finally I think it would take substantially more force to move the bow of a boat travelling through the water off course than it would to move a boat travelling on a trailer off course. I don't think the test as described in these posts is valid. I think the Mythbusters are busted and need to do this one over again.

Seaplane Pilot · 04-26-2007, 10:15 AM

The way the damage occured to the boat in the photo just does not seem probable. I'm no accident reconstruction engineer, but it looks too perfect. I would think that a boat hitting a piling head-on would cause more of a blow-out effect than a straight cut out as shown in the picture. I too think this was a staged photo.

There's much discussion on the Discovery Channel message board about this Mythbusters episode and the accident in general...it would appear this is not a doctored photo and the accident really did occur.

I think they should do a program on GFBL going over the witches. Nah that would not be nice.,

jrc, they were trying to bust the fact that that accident happened at only 25mph.

I think they have a lot of work to do if they really want to call it busted. Maybe crash a similar boat, in the water, using a remote system, or something. The Mythbusters usually go so overboard, I was surprised at how little they did with this one.
