3D Printed Hydrofoil Surfboard - Will it Work?

- A hydrofoil is an airplane-like wing structure under the water attached to a surfboard that generates lift. In this video I will mount an electric motor that will make it possible to lift out of the water and "fly" above the water.

I assume that the wings bend and a lot of lifiting power gets lost. Try to Analyse the under water situation by using a GoPro or such. Great video. Love to see part 2
Bump
That was my thought as well. Given how thin they are, when put under the load of a full person they probably just deform to the point that there is no lift
i thought so too
When I've seen commercial foils, they were VERY stiff - all solid CF and resin. I think the 3D print / wrap approach is not rigid enough Maybe 3d print a new one with room for a truss rod?
Or maybe good ideas from people that have created successful boards.
The presenting and editing makes it such a joy to watch! Nice job Simon!
Chaotic Evil editing at it's finest
It so satisf.....
I just want to say that I love the humor laced throughout your builds as you run through the trial and error process.
Great project ! Your main wing looks quite small, I do kitefoiling and the typical front wings are around 800cm2. Then the wingfoilers use bigger wings like 1000 to 1800cm2. I think you should try at least a 1000cm2 front wing with a 300cm2 rear wing for it to lift you over ;)
I hydrofoil a lot and if you were to stand back a little more that would of definitely flew in the water. It’s a huge balance game.
I have also a foil but electric and i think that you just need a bigger motor or bigger wing, is just not enough lift, if he leaned back more it would lift but the wing would stall immediately i have like 30h on a electric foil so i know a little bit
@@henryknowacki3554Yeah I agree stall or un-natural flight angle on the front wing could also happen instead of flight. Definitely more speed could help too no matter wing surface area. However, these are all things worth trying but stance would be an easy test before tedious fabrication.
Yes ne needs to lean back more problem is the box to all the electronics are right where he needs to stand so he'll have to address that somehow.
My gut feeling, is that the box is in the way, so he can't stand back any more. Something to consider for future designs I guess.
yeah he needs to be able to stand in such a way that his center of gravity is a fulcrum for the wing
I really like your video style and how you show your mistakes and your trial and error, and you have great dedication.
Edit: Is it possible to put jets on and have water cooling run trough the foil in to the board?
The foil sticking into the bottom of the board was hilarious! I think you need much much bigger wings. Also wings with a lower aspect ratio will make them stronger and more stable at lower speeds. Look at winging boards for inspiration.
Not necessarily, since the plastic box was above the foil mast, it was preventing him from getting his weight back, also higher aspect wings are usually better at everything that isnt carving + yaw
great progress on this, looking forward to the next iterations 😎
I always look forward to your videos. You're not afraid to show the development process and the failures along the way. Keep up the great work and you'll hit a million subs before you know it!
You probably could have gotten it to work but you have the battery components blocking you from standing over the foils. My suggestion, for simplicity, is to add a footstop behind the battery and controller compartment. That way you can balance your weight over the foil. I don't think you have quite enough power to stand in front of the foil at this point. Maybe not even standing over it but worth a shot. Good luck. Can't wait to see your next steps and future projects.
That’s what I was thinking. What would happen if he left the foil as in bud shifted the weight back. One foot behind the electronics box and one in front.
Correct. If his body weight is too far forward on the board, the foil will never lift him.
Yup you need your weight centered over the lifting wing. Can't believe he didn't consider that fact when building this.
@@capodad2u has to be a lil in front of quarter chord to maintain stability, But at his speeds the wing is too small, he needs more power
Most commonly the center of mass should be directly above the front wing. Now the back foot is roughly above the front wing. It really seems that there is some lift coming from the foil. Just try to stand like Charles suggested and the board/foil should rise from the water. If not, then you check the angle/size of your front wing. Nice work, keep going!
What I like about this video is you present even the fails as a fabricator and designer myself I have come up with all kinds of ideas that in theory should work but it takes me forever to perfect and get them working the way they are intended so kudos to you for providing the video footage because people need to understand the amount of work it takes to get a CustomDesign working correctly
I'm amazed that the larger hydrofoil mast survived without being glassed. Great job on those new print settings! 👍
I love how you just iterate past things that don't work the first time. The little editing cuts are hilarious. Since I have no skills I can only suggest some Velcro in the electronics enclosure to keep things from sliding around. Oh and maybe a gasket for the lid. Keep creating!
Love the creative ways of putting on the wetsuit. I've been following all the jet-boards with great interest. Hopefully I can make one of my own one day. As an old guy who is 65, I can relate to issues getting it up. You're young and will definitely get it up the next time. The idea of using 3-d printed parts as a shape to fiberglass over is brilliant and should be real useful.
🤣👍
Love how persistent you are at design changes that will help you reach your goals.
I built my own hydrofoil through Clearwater foils and things I noticed with that is once you make it out of the water you lose all you surface tension/drag meaning you can go slower once you break free. Also make the wing thicker for more lift…
Your speed is fast enough to go up, but your wing is too small. Really impressive to see that the 3D printed mast resists with your second prototype 👌
Either the wing is too small, or it flex too much under pressure. I would recommend a full carbon piece.
@@AlexLefevreArt it's both
I agree it is both.... but for sure the wing is to small and maybe the wrong shape for lift under load in the water.
I tried basically the same project last year except I thought the board building from xps would be too time consuming so I just bought a cheap board from my local decathlon. Also did some research and found Ray Velinga' s videos explaining the hydrofoil calculations. he also has a book its a great read, it would help you a lot.
One other difference between your design and mine is that I used two aluminium box section to strengthen the 1 m long spar, İt works great.
now Im building a much stronger v2 cause the first one broke on the board-spar joint while testing.(on sea with me on it while my dad was pulling me with a boat. which was terrifying to say the least)
You should video the building process for the second version bro!
big 3d prints like that really need some kind of extra strength, either box or threaded rod tightened down a bit like re-bar in concrete - I find thinking of 3d prints like concrete is good for the design process
@@trif55 Very nice analogy. When talking about pla I pretty much always use concrete as an example, cuz pla is stronger on compression then tension especially if the print lines are perpendicular to the force.
Also its stronger than some materials like abs but not as flexible.
I also used Al box section and shrink-tubed the bits. Not as strong as FG skin, but nice and smooth.
@@OzAndyify interesting 🤔 now I'm thinking what if I shrink tube after fiberglass/epoxy.
Does shrink tube peal off easy.
Your delivery of lines and editing is the best. Always makes me smile.
The amount of patience you have its amazing . very inspirational
I'm a windsurfer from Germany. I'm pretty shure, that you need a bigger front wing. (maybe out of carbon)? You are really fast, so fast enough to get up.
Also your Board is really long. The Foil Boards in Windsurfing are a lot shorter and wider. Then the board ist also pushing more water down. And maybe you need to shape your nose a little more like a windsurfboard.
But so far, great job. Be careful, if you're getting it and the Board ist lifting it will be very unstable. And if its lifting to much, the foil will get out of the water und dann you will crash very hard.
Amazing project.
You probably need a bigger wing with a stronger material like carbon or even glassfiber to decrease the flex...
Honestly like your videos because you never back down if things go wrong or stuff breaks. Looking forward to the next part!
Your editing is fantastic. So much fun to watch and learn.
you can check out actual foils for windsurfing boards to see how they do it(shape and size). i'd recommend windsurfing ones because those carry the most amount of weight(bigger board and a heavy rigg so a lot of weight)
Or a downscaled one off of a moth (sail boat).
@@moite2665 if the structure scales properly then sure. windsurf foils are the perfect size though so they'll definitely work
Impressive. An inspiration to continue with our projects...)) Thanks
Seems like you're on the right path. Keep going, I'm sure you'll figure it out! Can't wait to see it.
Respect on the determination and execution, hope to see more
check the flexibility of the wings, i suspect that they are bending giving you a different lift capacity than what it has been modelled for. Also a taller mast will give you easier lift, så perhaps the wing you have is modelled for no flex and tall mast, so you will need more power through speed to get equivalent lift. you can also make some cutouts at the back of the board reducing the trailing edge and thereby drag. Last thing, you might be able to get it to lift with some "pumping" but then you might just break parts. Great build though! and great storytelling of the challenges!
this is probably right to some extent
Yeah, i second this. The wings seem like they are potentially not strong enough and are not keeping their shape.
Your an inspiration mate. Keep it up.
That’s awesome. I’m always waiting for another video of yours. Truly an inspiration to keep myself of the bed and start working on a project. Keep it coming💪🏽🙏🏽
Im hyped to see the new wings installed, nice project !
Perhaps changing the incidence on the wings could help? Also I think you're right that lighter (and maybe stiffer) wings would be necessary.
the lift coefficient of a profile change if the angle of attack change, but also the drag coefficient increase if you move the center of gravity in the
back of the board.
a good way to find the best shape of the profile can be to use standard iso profile ,size the bigger wing to create such a lift taht should bee more or less equal to your body force plus the one of the surfboard itself and then computing the rear wing applying a momentum equilibrium.
in other words in order to deesign easly the wings the procedure can be:
1 choose a standard profile for water application (you can find on internet)
2 consider that the angle of attack is 0
3 size the main profile to counterbalance the structure and your weight
4 size the rear profile looking ate the momentum conservation equation (if there is an offset between the center of gravity and the main profile lift force you have to consider it)
A couple other comments point to the biggest issue with your wing and not generating enough lift. In layman's terms, with a higher aspect wing (wider in width and narrower in height), more speed is required to generate equal lift, than that of a stubbier style wing. When you pick up speed you can clearly see the board trying hard, but there is just not enough surface area to make it for the max speed you can get up to. When you go to a higher aspect wing, you will increase your drag significantly, but the trade off is you will able to be get the board up an foiling!
Foiling SUP downwind setups which are popular would be a solid place to start given the length and weight of your board, or some of the larger efoils, like getfoil! Great video as always my man!
PART 2 please and thank you!! Great work, man!
As a foiler myself all you need to do is move the mast forward which will create more lift. And only a small movement which be very effective. You'll also want to adjust this setting quite a bit so make it adjustable. Great effort by the way, love it 👍
he definitely needs a bigger wing. trust me, mine is small and bigger than his
@@kstorm889 yeah I agree, I'm running a 950cm2 wing on a fairly small board and his looks smaller than than that.
Great work mate!
A couple of thoughts:
1. The lift created by the hydrofoil is proportional to the size of the wing and the angle of attack of the wing.
See if you can design a few different airfoil sizes and add a method to adjust the angle of attack and test them.
2. You may need to make the connection between the board and mast stronger. When the board is out of the water your entire weight will need to be supported by that joint.
Consider doing a test on land where you attach the mast to something solid and then stand on the board. If it doesn't break, you're good.
Awesone to watch this video Simon! Nice editing as always :)
The 3D printed foils n Mask didn’t break is amazing and your patience is exceptional. Good work.
Foils are cool, but Efoils are pretty damn sick too! Wish they weren't so top heavy thanks to electronics... someday I'm sure that won't be an issue. Really enjoyed watching you learn haha
Awesome idea and nice to see how far you already got with this. I did laugh a bit at that first design, still surprised the wing itself didnt break even in the second design. I think the wing is deforming from all the upward force it is receiving, you may need a slightly stiffer wing even.
Edit: ah i’m not the first person who noticed. 😅
its cool to watch! Nice job Simon!!
Great build! Way to persevere. One thing which you might know, is that adding extra wall thickness when slicing has a much larger effect on strength and stiffness of 3D printed parts vs adding infill. It's why hollow structures can be very strong while reducing weight. Love what you are doing. I watch it with my kids. Best regards.
I love your edits, makes the videos really fun! Can't wait for more!
wings definitely need to be stronger, they are likely deforming too much under the water to provide the needed lift, but otherwise this looks great so far, i'm sure there's lots else to do before next video. lol
Awesome man, you got some good speed up too! Can't wait to see the next iteration! :)
amazing project! Well done, tough endurance to make it working !!!
I am looking to to build 1 for myself for a scientific experiment soon - just curious, how much did all the material cost you? Thanks so much!
So many of these kind of projects on youtube are flexing by making it look easy and like ti worked first time. It's so great to see the iterative process.
As for what I'd recommend: A bigger front wing will mean more lift, at the cost of a lower top speed. Looks like you're right on the edge of breaking free.
I agree with the comment's. A great deal of people try to make perfect video's. I like the humor and the failures as much as the success. Looking forward to the next video
Sick! really looking forward to seeing that thing lift in the next video!
Brilliant to watch , fantastic progress, it’s going to work keep going 🤙, thanks for posting
Nice, nice. Good work AND presentation.
Looks like a fun project.
Very entertaining video showing warts and all. Know you will keep trying till you get it. Thanks so much.
Nice work. Back foot should be placed directly above mast. So you need to be much further back. Maybe bigger foil. Stiffness of all parts it’s important too. Speed looks good.
really cool project, please continue that
My suggestions:
Place your center of gravity above your front wing.
Cover all of your printed part with thick layers of carbon fiber, especially in mast connections . With glass you are way too flex.
Seal better your battery box.
Keep your speed controller as cool as you can.
I'm really impressed that you get that fast with this setup.
Looking forward for your follow-on video.
Keep it up.good luck
Its fun to watch you grow bud. You have come such a long way.
Sick! Great video. Looking forward to the next iteration.
Looking forward to seeing the working product.
You build it, we love it. I continue to dream harder. Great job.
I love the shed man that looks really cool
Laughing out loud when the fuselage drove itself into the board! haha
I find that when using a store bought e-foil sometimes you have to place your foot on top of the mast in order to make it lift. this is exactly where your electronics box is...
What a cliffhanger, DO BIGGER WINGS!
Nice wet suit transitions!
Very nice!👍😁 Great job and video!
Awesome. Persistent always pays off.
Love this series and great video editing
I was looking at 3D printed wings for a while and was worried about them breaking. Happy to see it works and now I know I can use a 3D printed one too.
I've really got to admire your persistence and your dedication and getting the job done and how quickly you can change your wetsuit laughing good job good job great video it works need done on the design but you know that kudos
Very nice design!
Keep it going man! We love your work
Glad I stumbled on this channel! Super interesting 🎉
Its such a joy to watch you and your great designs
That's badass, from that first video I saw of a Hawaiian guy riding an unpowered hydrofoil board-I instantly knew that eventually powered hydrofoil boards were going to be awesome. I even tried to get my friend who builds aftermarket high performance wave runners and jet skis to build a prototype. Awesome work on all that 3d printing and building, I look forward to the next one.
Keep up the good work. The mast the wing is mounted to may be flexing forward from the thrust pressure. You may need a brace going from the front side of the motor mount diagonally (45 degrees) up to the bottom of the surf board further up towards the middle of the board (front to back).
Интересные эксперементы. Спасибо за ваши работы
Very nice project !!
You can build anything! Love your vids!
Great stuff.
Couple of suggestions.
It's all weight shift when controling the foil. So stand above the front wing.
Do quick rocking from front pressure to rear pressure and back to front foot pressure to get flying.
Much easier to do on a shorter board and with a flat deck.
One foot either side of mast is essential.
Your videos are always enjoyable to watch
I'm not smart enough for any helpful suggestions but I really do like this project. Good luck with the next iteration.
도전정신이 정말 좋아보입니다. 응원합니다.
The cut just before peeling the plastic had me absolutely dyinggg 😂😂😂
Honest constructing....top man.
Great video as always, Simon - you are a legend. As for those board, I guess maybe give it pitch control on the wings? I think that's what the sailing boat things have to account for different wind speeds. Good luck!
I love this. I never thought of using Fiberglass on 3d prints.
Nice work man. It will fly next time and your Cool Score will go off the chart :)
I saw a comment about running a fluid simulation I agree with that, also maybe increase the surface area of the wing looks small relative to the board , also change the angle of attack, should generate lift much earlier, looking forward to part 2 😊
You just earned another long over due sub. Good luck with your projects bro.
Rear wing is upside down. Fantastic effort. Keep it up
Awesome job, I love seeing the failurs and then success
this was pretty cool. would love to see an update. super interesting.
What an epic adventure! Honestly, I call this one a win
the editing was fire in thus one!
Foiler here. You need a larger wing. Like 2x the size. The larger the wing the less speed you need to get flying. Double it and try again, also need the surfaces to be baby smooth. Nice work so far!
awesome project, really liked the video! Keep going :)
I love your videos!! Always amazing 😀
Could watch this all day.
