- This is just a prototype test for my undergraduate thesis. There's still much room for improvement ..
I hope you'll enjoy it ;)
Designer: Jean Paul Farrugia
Building and Construction: John & Jean Paul Farrugia
Cameraman: Daniel Abdilla
Music: Colomb, Nicolas Jaar
I just came across this video.Jean Paul Farrugia was a student at the Faculty of Engineering at the University of Malta. He was an excellent student and his project was obviously regarded as one of the best of that year. This was the first hydrofoil ever built at our University and considering the limitations, Jean Paul deserves all the congratulations he can get. It was a good design, well constructed, strong, well finished, kept simple, light, and yet with very little twist in the hull. Considering that the foils were straight, all the lateral stability came from the weight distribution of Jean Paul himself. Jean Paul Farrugia should consider reading for Ph.D.
As we say in our language, Prosit tassew..
+Carmel Pule', Thank you for your kind words.

I just saw this video you made many years ago when you were a student. Many compliments, the job you did was... amazing !
I whish you all the best about your job, career and your life !
I love this.. You should put a video for the making of, step by step.
I was also wondering about stability. Introduction of some stabilty would be a fine continuation of the project...
Props to the school as well
as i've said in the description, this is only a prototype which was designed to fly in a straight direction. right now i'm designing suitable ailerons and flaps in order to bank and maintain pitch and roll stability.
Were you able to build the second design?
how is work the v2 or v3 of this foil? any video of the new prototype?
I would have had the foils descend like in a sailboat dagger board and then pin them in place.
I spent so many time watching vids how to adapt hydrofoil on boat until now, no one like yours... Very good jobs.
Many many Thanks for sharing with us 'ur skillful knowledge... U can earn a lot of money !
God bless U. Best Regards :-).
What an awesome project man! So many people waste their lives on stuff, that is something you'll remember doing forever. Long may it continue!
Very, very impressive! I was amazed by how little power your design needs!
Excellent job!! I had never thought before that the foils could have been made out of wood!!!
I like that hull.
Music spot on. (I certainly don't usually say that!)
Subbed, I certainly didn't expect to do that either.
Well I am quite impressed with how stable it was in the video. I now see that you do have control over pitch since you have a manual control for the angle of the front strut and foil. Anyway, it is a fine looking craft, congratulations. Looking forward to a video of your next iteration.
I'm not gonna lie I thought that front foil was way too small at first, but it worked beautifully! Amazing work!
Beautiful, elegant design.
Deserved a more glamour at the launch 😂 love it!!!!
Yamaha 2hp outboard. Here I was only using half throttle due to the ventilation of the foils.
You may investigate a propellor with more forward movement allowing for more speed if you do not need all the power for take-off.
you were using half throttle cause your foils are to long for the outboard shaft, lol
How about 4 flip down foils? Attached to the front spar and transom. Possibly the outboard on a jack plate?
@@jamessutherland5107 Quadrofoil have beaten him to it... and done a very nice job...
Is it faster and more economical? Looks like you need a longer stern leg?
Nice work, and I'm looking forward to the next video.
It's pretty awesome
And, ventilation of the Propeller...
-Wow, impressive project, yes!
nice job except that you have to mount the motor about 6" lower to get more trust and the pick up of water to keep it cool.great job habib. regards from Canada.
This is amazing!!
Sick and Amazing!
Great build and video. Thankyou
WOW This is impressive!!!
Great Video, Keep it up!!
Looks like a nice idea, could add it to a flying dinghy to reduce hull drag and get airborne easier. Well done.
Fantastic!!!
Fantástico!👏🏼👏🏼👏🏼👏🏼👏🏼👏🏼👏🏼👏🏼
extremely nice made congratulations
Well done.
Great video
epic project bro!!!
what type of reactions do you get???
so cool, and back in 2012 I love it
The hull is a work of art. The hydrofoils work perfectly. All this on 2hp at half throttle!?
Very cool !!
Beautiful work! Can you give some details of the airfoil used, and the anheadrel or deheadrel and the angle?
Pretty!
good job ,runs great with small HP
Jean, at what speed does the boat start rising?
Im planning to put a hydrofoil on my motorized kayak too. -Bob
Well done 👏🏻👏🏻
All you need is a longer leg on the motor. Great build!
AWESOME!!!!
Good job!
did you extend the drive of your engine to ensure the prop wouldn't be too high after lift? I've been thinking about building a similar craft for my undergrad senior design project, very cool!
cool, im going to show this in my class when i talk about hydrofoil. Thanks
Génial 👏👏👏👏👏👍
felicitation pour l'excellent travail, Jean Paul !!! Ou est ce lieu? Le bateau est en bois ou en fibre de verre?
I didn't know that such a magic existed :)
BRAVO!!!!
Fantastic build and video!
I am looking to add lift to the back of a 7,000 lb 28ft boat. Can you suggest the size of 2 hydrofoils which would be needed? Thanks, Wally
Totally want to build one of my own. How did you know the foils would provide sufficient lift at that size?
Bring that craft to NY!
Boat name : “who you foiling “
Excellent project, well done. What was the power of the engine pls ? Thank you
Awesome boat! Do you have any plans or specs/dimensions you could share?
Félicitation, la finition est tres belle.
nice work
Wonderful! How much does it weigh? Looks like your holding air without the motor!
XLnt job congratulations ! like the Wright bros you flew. unlike the Wright bros you had no steering. to effect steering anhedral or dihedral in the foils would have allowed the craft to bank stably. Then steering could have been affected by a movable front foil or outboard thrust. beautiful and successful venture you did. I bet you didn't stop smiling for a week.
Superb!
I don't see any surface follower, or controls. Do you control it by moving your weight?
With advance in small home shop machinery, are you able to improve the design and build upon your thesis.
Look forward to it.
Well Done !!! :)
Nice!
How about turning , how stable is it?
Would it be possible to make a wakeboard like this? The ones I find online only have a hydrofoil at the end. But it would be a lot easier to build if one was in the front and one in the back, just like you did it. Do you think it is possible?
ki ka already being made along with surf boards
Aaand it is working, nice
Realy nice.
I subscribed just to break the evil number of 666 subscribers and send this some blessings toward this guy, but realized how blessed this guy is already!
Gr8 job & such a tiny outboard.
A Q if l may. The foils even though they worked well. Wouldn't it have been better if instead of being flat that they had a V- shape to them similar 2 the hull shape.
I am no marine engineer by any stretch. And not a Sydney Australia resident but the hydro foils on Sydney Harbour have that V shape.
Other than that a fabulous job & fuel saver. 👍👌
Its looks great and very stable. Would it not be more stable if the hydro foils had a dihedral?
fatatomicsausage I think a small amount of dihedral would allow the foils to be smaller with the same stability. Still it is a very good achievement. Bravo.
Stability drops with a wake id imagine but I just discovered this tech 10 minutes ago
Very GOOD. So the foils are fixed (non controlled) and the hight depens on the speed of the boad: Faster High - Slow Down. Very easy.
Great 🔥🔥🔥
Congratulations awesome
Bravo! (nice music too).
I assume with the amount of lift that you could get away with smaller foils?
I would bend the sides upwards at a steep angle and use smaller foils. That would provide much greater stability.
Did you use a long shaft outboard motor? We only have a short shaft and planning to make a similar design
you could try electric motor maybe. it could be super quiet :) and it looks cool
Cool!
did you buy the plans or design it and how can I get a copy? Not sure I want the foil but I do like the boat
So cool🤓
brilliant
Awesome
Can you tell me some info about your hydrofoil boat? I’m working on a similar project and need some guidance.1. What is the length and width of the hydrofoils? 2. What is the weight of the boat and payload? 3. What speed did you need to lift the boat out of water? 4. Did you feel any speed increase once elevated? Thanks
well done
did you used a particular marine ply for the hull sides? Okoume maybe? from where did buy it?
Which speed you get and fuel consumption?
Is it 2 hp engine?
congrats
At what angle did you put your hydrofoil at? And how did you shape your hydrofoils?
That is sweet!! Man I'd like to make something like that.
do it
Do it
Nice...
sick
TOP!
wow jean :D
Bravo.
How does your boat maintain roll and pitch stability? The foil angles look fixed.
Nice👍
Never thought the music was nicolas jaar!
the work....
Это мы придумали !!! 80 лет назад !!!!
Do you mind sharing what you used to shape the wooden fin?
well that's cool
did you glass the foils? how did you reinforce them???
Bravo
Well Done :D :D :D
You need a longer lower unit the prop was coming out of the water towards the end of the video
Gabriel Hernandez Without any doubt. As you may understand this was just a prototype..
that's called surface propping supposed to be that way
@@walkertongdee The prop has to be designed to be surface piercing in order to it to work well, I doubt that the prop on a 2HP outboard was ever designed to run in this mode.
Cool
Eu só queria saber o que acontece no caso de uma colisão!? Sera que apenas danificaria ou afundava o barco???🤔🤔
