May be a silly or stupid question, but what is it about these beasts that creates the huge rooster tail? Doesn't seem to matter if they are piston or turbine powered. kip Its a combination of half of the 16" prop and the skid-fin that throws up 2 tons of water. The current boat throw more of a rooster tail in the corners as they have a way bigger skid-fin.   |

great stuff calvin! i'd love to hear the blue blaster run again.  duane Thanks! Here is the sights and sounds of the Blue Blaster.  But of course in real life the sound or as I call it, music is absolutely beautiful. It was even echoing off the bridge, which was kinda funny. |

That Atlas boat has a great paint job.

A great example of a 2-ton Roostertail! Absolutely awesome!  |

Chip Hanauer getting the 6,000lbs 1977 Atlas Van Lines completely out of the water going a conservative 150mph into turn 1. BTW with no seat belts (no seat belts in open cockpit hydroplanes back then - it was considered dangerous)   |

i wonder what was going through chip's mind as he sat in bill's boat. duane I know he's admitted to doing so in the previous times....but its hard saying if he did this time as this was a "new" rebuilt Merlin they were testing out....so I bet he was really trying to pay attention to how things were running..... There was also a bit of drama, as on their way over during the travel from Seattle to Tri-Cities, the engine shifted over a little while the boat was being transported on tilt, which made the prop shaft alignment go off. So they had to fix that before they went out. Then while they did the first test run it had a fuel leak that they didn't notice until they brought it in.....so that could have been bad as it could have caught fire while out there. |

I also learned the museum gets some their work done on their Merlin's by Roush Aviation. www.roushaviation.com/ |

As I mentioned before, I grew up in San Diego and Bill Muncey was a local legend. I saw the boat around town frequently. The "jet" boats are cool, but those old airplane engined monsters were the best. MJ |

great shots calvin!
one correction though, bill muncey was a national legend not just local.
as a kid, i remember seeing him in the pits in miami and he just seemed to have an aura about him.

Back then hydroplane racing was more of a nationally recognized form of motorsport....any more it's mostly just known here in Washington State and a good amount in Madison, IN. Yep, everyone loves the ex-WWII aircraft engines....nothing beats the unique sound they put out.....and how important they were in helping win the war makes them even more special. |

Yes, he was an incredible spokesman for the sport, he simply was hydroplane racing and keeping it in the national spotlight back then......Muncey and Bernie Little (Owner of the Miss Budweiser) were very instrumental in keeping the sport going..... |

That sounds about right: San Diego is famous (infamous?) for luring stars late in their careers then claiming them as it's own. Willie McCovey and Ricky Henderson are just two sporting examples. They also like to claim Pearl Jam (!) because Eddie Vedder lived in San Diego for a bit. I think it's all part of San Diego as a whole feeling a bit of an inferiority complex compared to L.A. and San Francisco. Having lived in the Bay Area for the last 6 years, I think I prefer the charm of the city trying to keep up as opposed to the city convinced of its superiority. That's about as deep as I'm prepared to go. :-) MJ |

OK. I hate to do this but I've another stupid question. Wouldn't the boat go faster if the entire prop was in the water?  kip |

I'm, for sure, no expert, Kip, but I think that works for displacement hulls, like the offshore boats. But they have a guy to just manage the throttles, to control the rpms. Hydroplanes just skim the top of the water, a very small contact patch. Maybe Calvin, or Duane can chime in, with a better explanation.

This is actually a very good question. I bet not very many could even explain this?
I think this is the absolute simplest way to explain it....
It deals mostly with physics why there is only half and ideally one blade in the water at one time....where ever there is an action, there is a reaction.
My best way to explain it, I THINK.....its easier to pick up water and throw it out into the air, then throw water in water.....it would take a tremulous amount of power to push water back into water.
I think most of all it has to do with drag! eliminating drag of the other blades that are not producing useful work.
Also the pitch, and the speed have alot to do with everything too!

That was a very good explanation. If I had had a prof in college that explained physics that well I probably wouldn't have gotten that F. Thanks Calvin and clm1545.

I believe the prop serves a couple of functions. It obviously propels the boat forward but it also lifts the boat. These boats are referred to as "three point" hydroplanes in that they run on the tips of the sponsons and as mentioned ideally one blade of the propeller. If you look at side shot of the Atlas boat you can see the principal in great detail.
I have only seen them run once and that was at Barrie, Ontario, Canada years ago. Most were turbines but one was internal combustion, what a lovely sound.
This is a great thread on a model forum, very cool. Some incredible photography. Keep them coming.

Yeah, I believe you're right on prop lifting the boat as well! (I think I've heard that somewhere else too!)
Thank you for your input!

Yesterday I made the trip down to the Tri-Cities for the Columbia Cup, hydroplane races. I went by myself and did very well! It was 105 deg. and I handled it very well. I started out on the Pasco side so I could get some shots of them going into turn 1 during Qualifying and the Vintage Hydroplane race. Then I headed over to the other side of the river so I could go in the pits and hang out. Then watched the dash for cash race which was pretty impressive. Overall great day, I was there for 4hrs and it flew by. Here is my first instalment of pics to share, I have about 200 more to go though! LOL But here is the basic shots of the current Unlimiteds.  I got to hang out with one of my favorite engines out of the G03 Racing Team pit - the big twin turbo Allison V-12 - thats my only selfie since I was by myself - I had one of the lady crew members take my mug shot after I bought their awesome Go3 racing T-Shirt Here's all the basic side shots of all the boats besides one that had a mechanical problem and didn't qualify.  U-1 Miss HomeStreet Bank  U-3 Miss ACE Hardware Go3 Racing Team  U-5 Graham Trucking (ex Miss Budweiser T-6 Hull from 2000)  U-7 Graham Trucking (ex Miss Budweiser T-5 hull from late 90's)  U-9 Jones Racing - Les Schwab  GBR-11 Peters and May  U-16 OH BOY! Oberto  U-21 Darrel Strong presents, PayneWest Insurance  U-99.9 Miss Rock more pics and videos later |

Saw a all red hydroplane going west on the freeway through Boise last week. Since I was in the east bound lanes all I saw was the bottom as that was facing me.  Paul Erlendson And I guess before anyone jumps in id better ad that it was being hauled on a truck. |

It was most likely one of the Graham Trucking boats or the U-3 Go3 Racing as they are located in Indiana and all traveled over last week. But most of the teams are from Seattle. |

Unfortunate I didn't get to get much video of the U-3 Go3 Allison. Plus I was trying to get pics at the same time....then one of the turbos blew (?) on the 2nd lap of qualifying. If you have a good sound system, the Twin Turbo Allison rumble should sound pretty good!

You have to do a model of the Peters and May boat. What great colors! Thanks for sharing the photos. They are great. Glad you had a good time.
