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.

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. kzfaq.info/get/bejne/rZuShNSazZardXU.html kzfaq.info/get/bejne/sMiflbqYnZyuaX0.html kzfaq.info/get/bejne/od9io5CVydKzZpc.html kzfaq.info/get/bejne/rJ5-oLR-xNmcj3k.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.

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!!

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 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.

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.
@erwinroman42175 жыл бұрын
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.
@MrSunrise-4 жыл бұрын
@@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.

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.

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.
