This was a very informative video along a great way to show and explain varying sea conditions on the haul of different styles. Even though it was in model form it was the best way to show a beginning sea fairer with great info.
Amazingly well thought out design! I live close to a similar testing facility in Holland, called MARIN (Maritime Research Institution), and I've been to some spectacular wave and drag tests there, as well as their own propeller designing and tests - absolutely brilliant stuff... I have a solid and broad background in physics, and understand hydro- and aerodynamics, so this does indeed fascinate me.
There is nothing that compares to him ...he is absolutely stunning ... Exquisite... In the fact. that he can adapt to any variable of sea astonishing...
your discovery is awesome sir.i'm your a big fan.I like speedboat. Speedboats are the only mode of transportation where we live.our residence is in a Island. I see your all vlog.love from Bangladesh. 🇧🇩🇧🇩
These are excellent tests run by Safehaven Marine. In 1962 I left Chatham Dockyard and went up to Durham University where later I was transferred to the new university at Newcastle-upon Tyne. I used to often go to a Museum somewhere at the Town Moor and this Museum housed the Turbina the first British steam turbine ship built by Parson. There in the corner where Turbine as the house I used to see and handle a few stepped hulls which were similar to the models shown in this video. There must have been about a dozen wooden models all having different step arrangements including various airing ducts. I know that Turbina was moved from that Museum to another one " the Discovery Museum at Newcastle" and I just wonder what happened to those old models made by Parson. Turbina had a lot of propeller problems as the steam turbines where directly shafted to the propellers and Parson compromised on the problem by using three propellers on the same shaft of which there were three if I remember correctly. ruclips.net/video/w5bQqih0GEA/видео.html ruclips.net/video/zbobWg86J9I/видео.html ruclips.net/video/ky2p-ddlO6c/видео.html ruclips.net/video/v8NmQM_s8_E/видео.html
Model testing looks good but if you take a closer look in choppy conditions like in 3:33 the bounce of the boat on the waves affects the angle of the tow line thus the bow on the model remains upwards sliding through the waves.
Perhaps I am wrong, but I get the impression at 3:40 that the rope is lifting the bow. In that way you are influencing the free running behaviour of the model.
I'm into model Boats, and have made several designs through the years. I am currently building what's called a Outrigger. It consist of 3 main parts, one center hull 26" X 3.5" and 2 Sponsons on the front of either side at 12.5" X 2.5" and a overall length of 36". The Sponsons are connected to the center Hull by 2 Carbon Fiber rods, and the overall size of the boat is 36 inches long, by 24 inches wide. Itll run Fast Electric 6 cell 3976 Brushless motor, from Leopard industrial motors, with a 36 degree 1.75 inch Prop. @ 30,000 RPM, I'm trying to get 180MPH+. I have a smaller version running 3 cell batteries, and a 2056mm Brushless motor, with 34 degree 1.25 inch Prop, running 128+ MPH!! This new design, is gonna be a BEAST!!! if you will look online at a company called ZIP KITS OUTRIGGER RACING BOATS, You will see the kind of Boat I'm talking about. They want 175.00 just for the wooden boat pieces themselves, with no assembly at all. No motor, no hardware, Nothing but plans, and laser cut pieces you have to put together yourself. Hit Me up if Your interested in a outrigger to put together, and I'll send you one of mine, for @ 75.00. Itll save you 100.00!! Also, if Your NOT interested in going fast, and being stable in the water, this is not Your Boat. As it will be capable of Triple Digit Speed!! 100+ MPH!! have a good day, and SET THE WATER ON FIRE!!
Great video. What a challenge to construct such fantastic hull design. How much could the crew take with all those forces on their bodies over many hours ?
Hello Frank. Thats a great design. Never thought a mono Hull could work that way. Would it be possible i can make a project like this just for my RC boat?
Uhm, that is not a mono hull. It is more of a trimaran, with the middle hull in front of what is basically a catamaran hull at the rear. Not sure what you would call it though. a CatMonoComboHull maybe? Anyway, point is it's not a monohull.
@@minhtraoho8031 since it has 3 separate and distinct sections that touch the water. I would say that it is a trimaran. But that's just my point of view
I don't mean to negative but I'm not sure if towing in such a way gives an accurate reading of how the performs through waves since the bow is being lifted by the tow line especially when it's going over and down the back of the wave. Being propelled from behind, it might behave very differently.
If You are interested, I'm building RC Outriggers, that are 36" long X 24" wide. They run Brushless motors, Fast Electric, and are capable of Triple Digit Speeds. 100+ MPH!! These Kits are selling on E-Bay, Amazon, Ect for 175.00 to 1,000+ dollars. That's just the wood kit, No Motor, No Hardware, No Nothing!! Bass wood laser cut, and building plans, is all that comes in the kit for 175.00 to 1,000!! Its Crazy!! My kit, I built from Scratch, and I'm in the process of taking the Kings of the Mountain down!! There is a Man from Germany, with the ZIPKITS Outrigger he paid 600.00 dollars for, being clocked at a sanctioned event at over 285 MPH on Fast Electric, with a GPS. I have the same Motor ESC, Batteries, servos, Controller, and Reciever that He does, in My Boat. I'm going to be at a Sanctioned Event in Sep, in Florida, to see if I can break His World Record, with My own Hull Design. If I can pull this off, I have a Buisness opportunity to be able to sell My designs, to the Masses, way cheaper than anyone else, and it will be the Current World Record Holder, and I'm hoping everyone will want one, lol. My best Friend of 35 years, and I, Design Test, and Build, our designs, and were gonna make em out of Carbon Fiber, and Epoxy, So, they will be virtually Indistructable. Hit Me up if Your interested, and we'll work something out, and get You to having some fun. Good luck, and, SET THE WATER ON FIRE!!!
I want to make a smaller boat with a capacity for 4 peoples. may i imitate your concept as in that video? it looks like very stable. it's the best concept in the world.
Look closer... They aren't pulled from the front.. The string runs from a anchor point mid-read and runs through a loop in the front for forward stability
The way they did it is def better then just tiring a string on the bow. But I don’t think it’s nearly as accurate as say a real motor and prop or jet pump. Don’t know why they took all the time to make the pull rig instead of a powered setup
OK so where do I buy one of these models I would like to put it like as are no a 23 CC or maxim Raven and higher performance 2 stroke engine in it so that would have to be probably 2 and a 1/2 feet long maybe 3' probably would be good if you could get back to me . Best regards PS nice job C1 USN retired
What are you trying to achieve here, speed?? First observation; what your giving up for speed your losing in stability and control. Sooo, if your looking to set a speed record on a lake you might be headed in the right direction. As far as function use, or improving the concept of boat shape; I'd say, keep thinking. Also, you're having to go long in length, which is going to give up the added benefit of holding space; so no chances of a cuddy cabin or sleeper berth..not competitively Again...if you're hoping to achieve some sort of record on a lake worth investing obviously a lot of time and money; good luck.
(LOL) The mini me RC experts seem to know so much more than the people designing and developing and building these hull systems.Boy aren't they lucky they put it on RUclips so they can be steered in the right direction.
I applaud your safety related research and development. However, your testing of two hull designs towed in parallel is flawed due to the opposing bow waves.
the old one bobbed up through those waves just as well. you sure it ain't just black tight leather in stead of denim gov. (male or female which ever you prefer. ) kids. huh.
That’s all nice marketing hype but it ignores the actual limitations of tank (or open water) testing with a scale model. Testing can give you comparative resistive results but the only thing you cannot scale is the water itself. The first time you will get good empirical data is with the first full size prototype.
That leads to my question as a layman. As water density isn't "scaled" to the model, how are results converted to the actual mass and inertia of a full-scale prototype? Thanks.
@@erwinroman4217 Typically you'll use dimensionless parameters like the Froude and Reynolds numbers. You can't do both at the same time, so for displacement vessels people use the Froude number to get the wave drag and then do strip integration along the wetted area to evaluate the viscous drag at Reynolds number of the model and the prototype. I don't know what is typically used for planning vessels of this type. Norman is correct that really good data comes from the prototype, but given the cost involved, it is essential to do model work on any radical design to at least get into the right general area for the prototype. If you follow the other videos on this channel, you'll see that they added a hydrofoil after sea trials of the prototype.
I'm suspect of rope attachment (towing configuration) during trials. Power boats are pushed with props not pulled sails (ropes). I'm sure you have stacks of evidence proving your hypotheses, but that's all there are in real life demonstrations. You must push the boats with engines and the skill of drivers. Too many different factors to be considered to pull a scale model along side a rib and make any conclusions.
Small boats are not even close to reality when it comes to saltwater , any deviation can push o pull the hull all over the place . You have money to burn building a boat to survive the next cataclysm when it will happen. This dragonfly of yours can't stand a tsunami and can't hold provision for a long period of time. Building something how's banging on waives is a waste of time . Looks good for an rc ship ,but having people inside that one is like living in a washing machine in dry mode, no stone on kidneys after a ride that is certain.
Catamaran with a monohull bow. Catamaran for stability. Monohull bow for better wave piercing ability. best of both worlds

I very much appreciate the towing set up for the models well dun!
Greetings from Indonesia, the Aru Islands, Maluku Province, on the Indonesian border with Australia
Excellent to see the Tank Tests and simulations. Industrial Espionage is my 1st concern.
Olá meu caro amigo, essas embarcações são uma obra-prima, admiro o designer e todo desempenho tanto em águas paradas como em águas agitadas.
I know very well this type of Hull..!! congrats for your 1:1 scale,beautiful!!!

Thank you very much for all, I'll visit you.
I will love to see a PWC with that hull design. Maybe you can send it to Seadoo and make a lot of money!!! Excellent design by the way!
Model testing looks good but if you take a closer look in choppy conditions like in 3:33 the bounce of the boat on the waves affects the angle of the tow line thus the bow on the model remains upwards sliding through the waves.
Agree. You keep towing the boat in perfect direction when, actually, the proppelor would be out of the wather and no power would be generated.
🤩 una vera opera d'arte.. grande uomo!!
KAPAL YG HEBAT DAN MANTAP ....SANGAT SANGAT SEIMBANG DAN KEREN BANGET
Impressive design and engineering.
I think this boat is just so freaking cool
If money were no consideration I believe I’d have one for my own
Within the simulation test put a electronic steering mechanism for better results within high speeds and twisting !👍😏👊
I used to test pull mine using a food scale for I could see the drag weight
Perhaps I am wrong, but I get the impression at 3:40 that the rope is lifting the bow. In that way you are influencing the free running behaviour of the model.
Would like a model like 60" so i can make an RC model for my self. 😭

That's what they should have done anyway for simulation instead of pulling it at angle though the water.
And that's how the thunderchild two was born!!

Looks like a championship racing boat.
Man, you will killin the structural engineer 😅
Very clever, however, Boat's are not towed but rather pushed from the stearn. I wonder how you figure that into your equation?
Now that was a fantastic video KUDOS.
the video is perfect for testing the prototype ship model
Estava estudando e vi está lancha muito criativa. Ewald Otto Kowalski. Brasil.
Не понимаю по английски, но и так все понятно по видео, круто!
Would be great if you made a scale model RC boat or turned them into drones they could have some interesting uses.
Hey amazing love the videos.
She runs as smooth as glass.
Interesting hull design.
Super test super aerodinamik good
What are the models doing now? I would love to have one and make an rc version
Should make the boat remote controlled by starlink and seek out some 40 meter rogue waves in the ocean!
Uall the best vídeo about design boat!
That's an impressive design
I want to make a smaller boat with a capacity for 4 peoples. may i imitate your concept as in that video? it looks like very stable. it's the best concept in the world.
Is being towed from the front the same as being powered from the stern?
Look closer... They aren't pulled from the front.. The string runs from a anchor point mid-read and runs through a loop in the front for forward stability

Well spotted! I missed that on my tiny phone screen.

Me gustó el estilo del casco muy bello
Water is 8 x thicker than air so the models should be a bit heavier to compensate the ratio of the real weight of larger boat
1 day ill buy one of these - full scale
like a catamaran navigator
brilliant engineering
Amazing job!
Nice work
Thanks! That's awesome!
What are the disadvantages of this hull design?
Show de bola essas embarcações com motor jets, um sonho de consumo, vocês não querem me presentear com uma pequena embarcação?...
Selam sana , elinize sağlık.
Is the model scaled to weigh also or just size?
Very cool!
They run well going straight, can they turn
👏🏻👏🏻👏🏻👏🏻👏🏻
Good morning... Is it possible to buy one to make an rc model? Thanks
Bravo 👍
Nice...ill take a hull for RC :-)
Be a good fast attack boat or special operations craft
OK so where do I buy one of these models I would like to put it like as are no a 23 CC or maxim Raven and higher performance 2 stroke engine in it so that would have to be probably 2 and a 1/2 feet long maybe 3' probably would be good if you could get back to me .

I like it.
Towing from the bow seems like a dynamical fail- these boats would normally be propelled from the stern?

making it as a race yacht, maybe
Я, конечно, не специалист, но если модель тянуть за нос, то это не тоже самое, как в реальности, когда привод в корме.

Its a rough test to see jow each design handled in water
Testing
I saw a company working with that design in Florida in 1990. Didn't have elongated bow but the rest was just like your design. Ummm
Can't most of this be done on a computer with CFD nowadays? This seems so 18th Century...
Yeah, but those simulators takes some serious data and skilled programmers.
Need a electric model!!!!!!
It would be better if it was a swath Hull

All these armchair experts, yet none of them a yacht builders.
Towing the models is not the correct way to test them, put a motor on each one of them.
