Very impressive. The only disadvantage I can see it that it draws what looks like at least 14 feet, which is a problem in many areas.

Thanks for this Ray!.. Some great work you do!

At the first and second boat, the lever is too small to compensate rolling forces. Would (additional) outriggers with surface piercing dihedral foils make sense? What is the assumed take-off speed of the first two vessels?

As I wrote earlier, COMMON terminology assumes air is the medium. Terminology usage varies by profession, and dictionaries don't cover hydrodynamics. I worked for the organization named in this video. Hydrofoils fly under water.

@pznerd did you not listen to the words... better speed, less drag... more fuel efficiency.. pretty obvious if you think about it....

@PorkyPiggles 15 лет назад

If shit hits the fan it flies off in all directions. The term fly can be used for things without wings. I travelled from Budapest to Vienna on an old hydrofoil and it felt like I was flying. It certainly wasn't floating. Call it what you like.

The problem w/Hyrdofoil is the boat launch average 2-5 feet. So how would one launch and/or load its hydro boat? Not very practical. How would you dock your boat in most lakes?

@m1leswilliams 15 лет назад

So I'm correct if I say I'm going to hop on a plane and float to the Carribean... The term foil is a reference to the wing hydro for the medium, as in aerofoil. Hydro foil doesn't mean fly.

@justinwoods7640 11 лет назад

It is not flying, it is still in the water. However if we take the hydrofoil as a separate part of the boat then yes it would be "flying" but only hovering unless the hull of the boat is at least 10ft above the water.

@wookie_wagen 14 лет назад

would the bottom of the boat hit the bottom of what ever body of water its in?

@Ng.Vo24 15 лет назад

what if that hydro foil concept of yours hit an under water obstacle with it's foil, would that ruin it

@chuanist 15 лет назад

You've made a nice try at educating a small mind. However they frequently crouch behind familiar prejudices and strongly resist anything new.

@my1987toyota 15 лет назад

thats all fine but it probably has a 20ft draft at slow speeds wont be seeing one of those here in intercostal Florida.

So you like Hydrofoils I see. Well do you also like Musicals. If so check out "Hydrofoil - The Musical". It tells the journey of one mans quest to become foil-borne

@rvell7829 7 лет назад

Osho, I love your video. There should be more operatic hydrofoil videos on RU-vid.

@PorkyPiggles 15 лет назад

The principle of lift through forward motion of a wing is technically flying, through air or liquid. Being open minded is essential to scientific progress. If you think a boat cannot fly through water you're limiting your inventive thought process

@cartmanrlsusall 8 лет назад

it looks weird but she seems to work well

@anachronist 15 лет назад

Common terminology assumes air is the medium; try talking to a naval architect or engineer. Airfoils fly through the air. Hydrofoils fly through the water, that's why they are called hydrofoils. That's the basic way we look at it in the Navy, anyway.

@Scorpac 14 лет назад

@SWMoneyMaker and you think the USCG has no eyes yes? they will see the boat before you see them. so they will know whats going on with it...

@energyalt56 13 лет назад

In H.K & China there are a lot of big hydrofoil boats that carry 450 passengers or tourist

@anachronist 15 лет назад

Hydrofoils hitting things underwater (e.g. trees, whales) are a problem for any hydrofoil craft, not just this one.

@frnesbit 15 лет назад

Does not look very practical to me????

@anachronist 15 лет назад

Wrong. Hydrofoils do fly, but the medium they fly through is water.

The "Drug Boat" would obviously be going slow enough to the point where it doesn't go up to show that it is a hydrofoil boat which would allow the drug runners to indeed hide their drugs well.
