'Here he is, in his kite surfing gear' 🤣 Great video, informative and entertaining. I had no idea of modern day boat and sail/kite technology has come so far. Thanks for sharing
Latest speed on the training foil is 43+knots. The team are now finalising the design of the final foil (daggerboard) and aim to break 50 knots in Q4 2024 ready for a run at the record in 2025
How is wind a renewable energy ? I mean it's free; but it cannot be created. It's the result of low and high pressures and totally unpredictable... Very cool project though.
Fascinating that the boat can actually travel faster than the wind itself. That's something I'll have to study, because right now, I don't understand how that works. But I'm sure it has to do with the sail being at a fairly specific angle to the wind direction; and if that's the case, then the direction of travel of the boat must be pretty restricted as well. That would probably make sailing by this method for the transport of people or goods between ports or harbors impractical at this time. But it's still worthy to study and refine the science and engineering of the method, because ways around the limitations may yet be found. Looking forward to hearing how things develop. Best of luck.
@@kellyrobinson1780 Do not complicate your life so much my friend. Put a spoon under running tap water. On the concave side it will splatter you with water; on the ROUNDED side it will be PULLED into the water stream. THAT is how a sail/wing works. It creates a depression that SUCKS the object it is fixed to along/up. To go FASTER than the wind there comes a momenbt when your sail/wing is creating it's own depression and the faster it goes and the faster the air moves over it's surface, the bigger the depression = sailing faster than the wind. Kites are already used to haul large ships at sea and save fuel. It's al about the angle and the direction you wish to go in and of course t what speed. A ship is NOT going to want to go 50kts fast..... All you ned is for the kite to reduce consumption by 40% by pulling the ship along in the correct direction. Cheers.
Amazing project! Iconic and breathtaking design, by the way! Found this by chance while watching Sailrocket2 and will follow your record attempts from now on. (Will keep my fingers cross!)
The Boat design is just breathtaking. This is just amazing, just when you think we have reached our limits on water speed generated by wind only .... u guys just go and do this.... I am here for it and waiting to see that record go down!!! Go Team!!
I've seen this general design in a sailing boat engineering book decades ago. It was the optimal design for speed. I was intrigued by wingsails. Parasail kites are a step above.
Aside from the countering foil in the water, those 3 hulls are going to create a fair bit of drag. So as well as the foil cavitation issue, drag will also have to be resolved.
@@maxhugen the main challenge with this approach is in fact stopping the craft from flying. Hence the superventilating daggerboard foil to keep them down.
@@katamaranscom Sure, I understand that, having done force/drag calcs and max speed predictions on the F50s. Wish you success with that foil... and will be keenly looking for it's profile at some time in the future. 😎🇦🇺
@@katamaranscom Sailrocket made it to 65 knots. _I think_ Paul Larsen and designer Malcolm Barnsley incorporated some way to induce *ventilation* to the flat trailing edge of the cavitating foil. This should reduce the severe drop in pressure in that area, with a resultant reduction of drag. BUT this is guesswork on my part as Paul hasn't ever revealed how he got the foil to perform at those speeds, AFAIK. Will 80 knots happen? Possibly. Despite the fastest sailing foilers in the world like the F50s and the AC70s struggling to pass 50-55 knots, Sailrocket showed higher speeds are possible. Won't be easy though - it's the hardest nut for the team to crack IMO. 😎
@@maxhugen yes, I think I remember something about a Super-ventilating foil on Sail Rocket 2. Interesting to note that quite a few kite surfers have held this record, all planing. But there is a limit to how much kite power 1 sailor can handle, which I guess led them down the kite boat route. Also, on the windsurfing circuit, it's foils at lower wind speeds that win the races. As the winds and speeds pick up, they switch back to planing. That's with current foil technology of course. I have done my fair share of spinning out on a windsurfer at speed. It's a great way of going sideways and crashing at speed 😅
55 knots top speed so far (102kph). They also come up against the same issue over 60 knots: cavitation over the foil surfaces resulting in a loss of lift and increase in drag. SP80 does have a superventilating foil, but it's to keep the boat down. The main challenge is staying on the water with this approach
none of this would be possible without the invention of Ben Lexan's winged keel which he invented and fine tuned for the Australia II victory in 1983 when Australia were the first nation to win the America's Cup lifting it away from the US after 132 years of unsuccessful challengers.
a hydrofoil system could potentially be used to enhance the performance of the SP80 Speed Machine and increase its chances of breaking the World Sailing Speed Record. Hydrofoils are lifting surfaces that elevate the hull of a vessel above the water, reducing drag and increasing speed. By incorporating hydrofoils into the SP80's design, the team could potentially achieve higher speeds and improve its overall efficiency.
@@katamaranscom the team may need to develop advanced control systems to monitor and adjust the hydrofoils in real-time, ensuring that they are operating at the optimal angle and depth to avoid cavitation.
@@katamaranscom I asked AI the question , then asked it what is the best option - it said this ' The best option for the SP80 Speed Machine would be to focus on a combination of the following: 1. Advanced Hydrofoil Design: T-foils: These offer high lift and stability at various speeds. Surface piercing foils: Can reduce drag and increase lift, especially at high speeds. Adaptive control systems: To adjust hydrofoils in real-time for optimal performance and cavitation avoidance. 2. Optimized Hull Design: Sleek and aerodynamic: Minimize drag and maximize speed. Stability: Ensure the vessel remains stable at high speeds. Hydrofoil compatibility: Design the hull to work seamlessly with the hydrofoils. 3. Powerful Propulsion: High-efficiency sails: Maximize energy capture from the wind. Kitesurfing-inspired techniques: Utilize advanced kiteboarding techniques for increased propulsion. Cutting-edge materials: Use lightweight, high-strength materials for sails and rigging. 4. Crew Expertise: Specialized training: Train the crew in high-speed sailing techniques and hydrofoil handling. Physical fitness: Ensure the crew is physically fit and capable of handling the demands of high-performance sailing. 5. Weather Conditions: Strategic planning: Choose optimal weather conditions for record attempts. Real-time monitoring: Use advanced weather forecasting tools to make informed decisions. By focusing on these areas, the SP80 Speed Machine can significantly enhance its chances of breaking the world sailing speed record. It's important to note that a combination of these factors will be necessary to achieve the desired performance.
@katamaranscom I understand they have to follow the rules to make the record "official" but why not incorporate those things for after the record runs? Would they be beneficial or allow more performance?
It's just so far into what I'm used to, a displacement mono that does .6 .7 true wind on a close reach. Oh yeah and you can sleep on it because it has a cabin
Is it possible to implements of this technology? Transport, passenger ships of certain classes etc. Private yachts, transportation of certain cargoes, cleaners of plastic pollution etc. To reduce "carbon footprint".

They need to look at a Top Fuel Hydro hull !!!!! It looks like the nose of the boat is plowing too much water
Foils are unstable over 60 knots. You can't use an engine for this record, but if you could, planing would be the way to go like Spirit of Australia
When I see racing catamarans and this too I always wonder what if it was allowed to leave the water and sail as plane, how would one make it?
@@user-he4ue6is7k trouble is, you need some lateral resistance to get the kite to work as a foil. In the air, you will just be blown downwind.
It's just so far into what I'm used to, a displacement mono that does .6 .7 true wind on a close reach. Oh yeah and you can sleep on it because it has a cabin
Or you can do the same and better sleep in a catamaran and go much faster
