Thanks For sharing!. Am retired electronics engr. Making a 12.5 foot SUP for paddling, sculling or sailing using extruded one inch polystyrene sheets. The blank was laminated in a simple jig using clamps to form the bow & stearn curves.. It is beautiful. Getting it ready for fiberglassing with UN & BI Rutan glass cloth. (PS i designed 32 bit 1.2GHZ com;outer boards for military stuff like the Global Hawk drone integrated mission management cpmputer (IMMC) Motorola, now NXP has the lowest power integrated host processors. 130 times the MIPS of a 1968 IBM System 360 mainframe. LOL. Get paid what you are worth and vote with your feet. ❤❤

I'm a Tesla Senior Staff engineer and I must build one of these now too! THank you!!

A very cool project! The fact that you made it alone is very impressive. How can I contact you to find out some of the features of the technique?

Great project and a great job dude!!

RIP to that laser

Wow, you discovered something.

Nice work! Really cool to see this getting built.

impressive

New subscriber bro.

Awesome

I must have missed something I don't see you sailing the sailboat with hydrofoil I see it being towed did it ever work?

Dehler Segelboot 470 Olympia soll mit Hydrofoil und 10 PS Aussenboarder von Honda ausgestattet werden. Kannst du mich mit Know How unterstützen? z.B. mit deiner Matura-Arbeit oder Excel Sheet, Adressen etc. pp.

nice build. it would be fun to build an RC scaled-down version. at what speed does your boat hull lift out of water?

well done

Nice

Nice! Please never wear gloves when working with spinning tools like you did at 4:50. Very dangerous.

Nice! Very Nice!

Won't the forces be different from pulling to pushing with a motor?

scrap it..

The advantage of a single foil becomes apparent. You don't need perfectly balanced lift each side. Nice work and video thanks. Keep exploring!

Kids make the best test pilots.

Congratulations on this very interesting project. Please ccould we have a video of the boat sailing. John

How did you come up with the decision for how much wing area is appropriate (relative to your boat weight and target speed)? What made you chose this specific wing profile? There are so many to chose from (e.g. as NACA numbers) ... Btw: Interesting project, especially with the successful implementation of an automated electronic stabilisation. Congratulations! _(note: I also speak german, just in case this makes answering any easier)_

B r a v o !!!!!!!

Great work Lucas! I realise it has been sometime since the project... Can you make your electronics and control design available for me?

Bravo! Ganz gut gemacht, fehlt noch das heck-foil , dann wird es ganz ernst. Wann kommt das nächste video mit Heckflügel?

Your vertical controller works like a charm! Nice! You used infared or ultrasound or what to measure distance from sensor to water?

I hope you are keeping up with this video. What airfoil did you use and how did you calculate the size needed for the mass of your boat?

I think your main goal was the eletronic height control, could be the reason for completely disregard the KISS concept (there are already far more simple and less fail prone ways to mecanically do that), but lets put this aside, for now...at which speed have you foiled up, would you be able to reach such speed under sail? Adding lateral foils to a sailboat, you might have think in assymmetrical lift, to fight heeling forces, how would you reinforce (or completely replace) not only the spar but also, the mast's foot structure, to deal with the increased loads, without adding too much weigth? And finally, there is already on the market, a complete plug&play foil kit for Lasers but ... without Eletronic Heigth Control, for sure.

Outstanding!! Well done.

Keine Schwimmweste?

really amazing

Wow super impressive. Love how you combine electronics into it. I am in the prosess of combining two kayaks to a catamaran, and sail on it, and eventually hydrofoils. All transportable on a bike trailer for my electric fatbike. And the idea, is to chain drive my fatbike motor into the boat propeller. So it is a E-bike powered boat.

Very Smart. I wonder what it would do under sail speed wise?

Brilliant - how wonderful to combine two things that you obviously love - well done!

I built Tubby Tug in the past. I belonged to a boat club and everyone was impressed. coulc.it/boat I own a 1973 Chris Craft cabin cruiser, and to tell the truth we had more fun with the Tubby than we did with our big boats. It was great working with them.

Hey Lucas I was wondering if you could share your CAD drawings.

Looking forward to seeing you in the Alinghi team!

Brilliant! Thanks for sharing.

Where can I buy one?🤷‍♂️

YOU GONIG TO SAIL IT OR WHAT?

Really cool. But... Did you SAIL it??

Excelente trabalho!! Parabéns.

Hi. Interesting design but you will ultimately need a foil incidence control system. Research Hook foil control to vary the angle of attack of the main foils which could be linked to some trailing flaps on the main foils. Trying to control the incidence angle of the main foils using T foil at the stern does not work successfully. Believe me, I have tried it. You need an incidence control system for the main foils which will respond to their depth of immersion and vertical loading placed upon them. Good luck.

Need to put one on the bacl too

Haha wie cool! Hab deine Maturaarbeit mal grob durchgelesen. Echt Respekt :)

what servo motor did u use?

Awesome work guys ! A well deserved success !

Did you use sweeps (chirp) to read distance?

It would have been much better to see more footage at the end. Very cool. Fs ? Second ord pos. control? DSP on controller or do you just run recursion in std micro? Why FG instead of carbon fibre?
