This feels like one of those "if you can think of it, someone has done it" moments. Also, this is the sailing skiff version of a sleeper - make one that looks entirely stock above the water line, challenge someone in a Laser to a race, ruin their day.

Do you think these are class legal ? I think you'd be the fastest ten year old around

40 years ago I entered a race for Optimist hulls with unlimited sail area, but we didn't try foils, suitable material wasn't available. So I really enjoy seeing this working, in moderate winds.

i race in sunfish and if there were 50 flying bathtubs i would be shiting my self

The lack of a rocket engine is a major oversight, disappointed it didn't achieve low Earth orbit. Otherwise, jolly impressive. Cheerio!

Your grandchildren would have a hard time learning to sail in that. I learned in an optimist and they can plane in enough wind, but on foils it isn't sailing, its flying.

Amazing that such a small sail can get it up on the foils. Balance looks challenging.

Windsurfers foil quite easily, its the size of the wing, the smaller the wing the faster needed to get up, but the higher top speed, bigger wing is lower top speed but barely any speed to get up

@@pureprotein9597 windsurfs are way faster than optimists though. I’m absolutely amazed they could get on the foil with only 5 kts with such a small sail, considering it’s very challenging even on a windfoil

This looks like awesome fun! I want to try one

really amazingg - great job !

this is great, cheers!

Wow, fun project!

Love this!

It's looking like this single foil makes the optimist go much faster.

Freaking awesome!

Amazing!

Awesome!

Superb!

Really neat!

Make kits available to upgrade any small sailboat like the Banshee. This is great.

super... bravo...:)

Glad to see this has been done, the next boat I am building is a Mirror Dingy style sailing boat with a foil for flying.

I wondered about foiling in a Mirror. First boat I ever sailed. Not super-fast but fun when I was 12. Sailed a Laser next. They were alright in light winds but could be impossible when it blew up a bit.

Hi.wonderful it is. I built two dings years back down here in costa rica. Love your design... would like to copy it and try it with windsurf sails.. are the measurements available? Thanks

I really want to try that !

Pure Fun! (Ok, and some science behind)

Amazing.

This is great.

People keep asking why do this to a 50 plus year old desighn. The point is to test and learn about foiling as a common sailing practice going forward. The opti is the most common sailboat on the planet so it is a great hull to prove the concept. Stock hull stock rig. Amazing results from the foil.

Det var förbannad bra! Hoppas Team NZ gå lika bra!

is fantastic i want that optimist

Ah, Chalmers University, welcome. I hope you're prepared for an unforgettable boat.

Been around a thousand years plus, the flying proa, thats how it feels

GREAT !!!

The song that youtube recommends in the description xD

I wonder if I could put that on to MY optimist...

Great! :):)

I wanna see what the foils look like!

It needs an aileron like the foiling catamaran i-fly has, wich always tries to correct the hull to a horizontal position when on foils automatically. Then it is easy for younger children to learn how to foil sail with these flying optimists.

Performance specs? Great to see it on a small dinghy - I am about to try it on mine.

Do you have a drawing on the boat, so we can test with one of our old optimist

You should also check out the International Moth.

amazing

GENIAL !!!

I loved it

Take that to a opti regatta you will smash every one

When you max out your starting tools and amour:

there would be lots of demand if they were distributing it. I sure would buy one

Now it looks like a coffin with foils!

I was joking about a foiling oppie yesterday and didn’t realise that it actually exists

You're ready for the America's Cup

Foil on a nutshell. lol. Fun to see.

I once tied the bridle of an 8m^2 ram parafoil kite onto the top and bottom of the mast of my opi. went out in 26 knots wind. from head to wind while letting the kite inflate to bareing away to broad reach I could get planning in 4 seconds. GPS said max speed 16.2 knots boat speed.

That's mad. Doing 16 knots in an Opti!

One thing I don't get about these foiling sailboats is it looks like the wind could blow it over when they're foiling, but even in good wind, it appears they aren't heeling much.

Yep, and now, we have the "Americas Cup Boats" doing almost the same thing here on the last day of 2020 in Auckland doing 50knots in very light winds, It's most probably "Thank You Sweden"

We have an Opti at home. When Chalmers develops a kit to fit an existing hull, we'll buy one!

If you install airfoils can it lift the keel completely out of the water?

this feel one thise is verry nice

foiled again!

good for you , person's

I think this is amazing, isn't it?

I spent many years in my youth racing these boats, up to the point where I weighed 100lbs making me non-competitive against the younger 70 lb. racers. It would take a very stiff breeze to allow this to happen. You should take note that if these boats when tipped fill with water, it is all over till the tow boat comes. My dad, who built our boats would have been all over this if it had been thought of back in the 60s!

Plans? Where are the plans? Or can I just buy foils?

seems like a bit of a handful.

I kept on looking at the line dragging to the keel board. Thought you could get another twenty knots plus if it was slowing you down. Tony

That would be the ride height wand. Same system as a foiling Moth. It senses the water surface and adjusts the main foil trim accordingly to optimise lift and ride height above the water to take some workload off the sailor.

Imagine this pulls up on the start line and just shoots off, peak embarrasment

Is there a way to buy the foils?

It's really amazing! How can we buy it for our young sailors in Russia?

Hi, I am working with the RYA, helping in the digital world and we would love to use this video in a presentation at an event. Is this OK with you? Many thanks

Catamaran energy in a ‘very’ optimistic way ⚡️.

what speeds do you get ?

Förändring av formen på hydrofoilen allt eftersom båten ökar hastigheten, är det någon man skulle vilja eftersträva?

How tall is the skipper?

Great student project. I would also like to know if the hull is class legal. What does the boat weigh? It appears 5m/s down wind is near the lower bound for foiling. Is it possible to foil up wind in some higher wind speed? The obvious next step would be a larger more modern rig. The Clarks rig for the UFO is excellent for the price.

I, too, would like to know what it weighs. Obviously the foils aren't class-legal, but even if you removed them I'll bet the boat isn't class-legal. I'll bet it is way, way underweight. The minimum class-legal hull weight is 77 lb (35 kg). I'll bet this one is a lot less. (I don't know what the minimum class-level rigged weight is.)

Remember that the best foil is actual as close to the water as possible without touching. Being able to control blade height is key.
