Dave, is that the video on your RDP Facebook page? My son shot that video (fixbonz)

It’s on our IG and FB pages and while he may have shot a similar video he didn’t shoot that one.

Chase Gibson shot the one on mine.

Freedom One page just reposted RDP's Top Gun version of the video 😂

I saw they reposted a Ricky Bobby version of it too.

Cool to see that they appreciate some humor even though it was massive crash.

Between the water and lowest point of the boat. 70' if you scale it using the boat length.
That’s crazy high as that means it would clear transmission lines. Not saying you’re wrong. Just falling from that high and hitting the water can do serious damage add in the mph really shows how lucky they are.

I just scaled it like a set of blue prints. There's probably a computer program that could get the exact distance. What's a few feet though at that speed and height. It definitely slowed down in the air. I would agree on Luck or Karma as to how it turned out.

We've seen where chutes have helped the land dragsters with recovery (to a degree) in a flip situation, but they will come out automatically if something triggers it (ie engine pops or other things).

It seems to me with boats, the drag chutes on water dragsters still work on it because they capture water and air at the end of a run.

However I just don't think it helps when shit goes wrong though in a boat. It happens too fast for humans to deploy them and the boat may just wind up wearing the chutes and not helping any as it tumbles before landing.

I wouldn't mind seeing someone come up with a system for auto-deployment but it would have to be triggered on some kind of AoA sensor or a potentiometer should the boat suddenly veer off course or direction.
I can’t imagine pulling the nose of an air entrapment hull down into the water at those speeds would end well. I know they have them on drag boats but the hydrodynamics of them are a bit different than these large cats.

Here's the bottom line, these big cats at these very high speeds are 95% aerodynamic crafts, with NO aerodynamic control. Absolutely crazy imo that anyone will drive them, it's literally like playing Russian roulette, not a matter of if but when. And this is coming from someone that is involved in a fair amount of work for boats like just like this one.

We have gotten to a point where they need active aero surfaces to push these speeds, either a combination of tunnel vents, or a small forward canard between the sponsons, controlled by a closed loop system to keep the craft within the margins of a safe angle of attack, because the instant that bow rises just 1/2" too far it's all over with and there is nothing that can be done to save it.

Why would you pick aero over hydrofoil

About 90’ to the top if you believe the placement of the scale lines I drew below. That’s nuts! . Pic #1 is right before the throttles were cut when the props came out of the water

I believe the owner of Lickity Split was killed in that tragedy. Don’t recall seeing videos of the incident. Was the cause ever determined? Correction, the owner of Lickity Split was not onboard that day. There were 2 fatalities - Brad Kloepfer and Paul Selberg. Connie Kloepfer was critically injured and flown to Phoenix.
Connie died a few days later in the hospital. Brad and Connie were great people. We regularly hung out in Havasu over dinner or drinks. I didn’t know Paul. Sad.

The water drag on something like that, even when aligned with flow, would be exponentially more than an above water aero surface at a neutral angle of attack. It would be a speed impediment.

Not sure I agree with that due to the idea you’d make up whatever losses by lifting the hull out of the water at lower speeds and he’ll even higher speeds.. you can make it where the hull thing is ground effect

If you saw how much speed is lost by just a 1/4" of the water pickups being out of placement it would blow your mind. Also there is no way a hydrofoil could wisthstand the forces without majorly deteimenting the performance.

Upstaged them bitches in the flying penis. 😁
Glad the driver and t-man were unhurt. Testament to Pete's hulls and engineered safety rigging. 👍

No way. Water has way too much drag.

It ended up right side up at the end but hit the water upside down..

To echo tank it was extremely similar to Mike F outer limits crash. When you look at the aftermath of the OL crash it also ended up right side up but the roof canopies appear to be gone..

Watching the vids side by side this one almost seems more violent than the OL crash (depending on the video you watch) but they came away pretty clean.. luck of the draw I guess.


Todd Taylor spoke to them this AM and they said they are already excited to get it back together and set records..

Rewatched the OL incident this weekend after seeing the F1 video, my non-engineer brain says that when the OL clipped the bow on its first rotation it brought the boat back down to the water much quicker than it otherwise would have. F1 getting a clean rotation on the first go around allowed it to stay in the air longer and scrub more speed. Additionally, it seemed like OL landed more directly on the canopy where the F1 came in nose first and rolled, further dissipating energy away from the occupants. Luck of the draw for sure.

Since this video has made it so far and wide outside of the performance boating circles, do you anticipate any changes to the event next year? My family that sent it to me all said how lucky they were that it didn't blow over onto spectator boats, I don't see that as being a possibility but an interesting outsider perspective.

It ending up in the spectator fleet due to a blow over isn’t likely.. however a steering failure, drive failure on a twin bravo boat things like that it is a possibility but doesn’t seem to ever happen.

All of this and I have not seen any mention of the wind on Saturday possibly being an issue. I was pulling out of Thompson bay about 45 minutes before this happened, and wind was blowing like a MoFo.. gusts were crazy. I leaned over and told Terri, there gonna cancel the shoot out, no way they can run in this wind….

How dare you try and bring logic into this discussion😡

The consensus is they need HANS devices and bat wings and everything will be ok😝

LOL. Accurate measuring right there...
😁
I actually used a ruler on the screen to scale that by the boat length, I think it was 19/32 =40’. 👌🏻

The field drawings I send to architects and engineers when we have issues with design are of the same quality but they usually have circles and the letters wtf on them.😆

I remember when a certain DCB went thru the spectator fleet years ago at Desert Storm...WFO.
Of coarse that was simply due to trying to beat Predator...and never lifting.

If the conditions were perfect every year they would have to change the name of the event!

I agree it was a windy day and of course that could have been a factor. But I feel any boat going over 180mph always has the possibility of blowing over. Theres been accidents before where boats blow over and there was no wind. I don't believe there was any wind factor in the Outerlimits blow over at LOTO but I could be wrong

imagine how spectacular the crash would be if a foil came apart at speed.

Curious if Shane T tuned it. That’s a bad mofo right there.
