You failed to explain that there are two different kinds of hydrofoils. Surface piercing and totally submerged. Boeing was the first company to make totally submerged foils it took three gyros just like an airplane they call it the Jetfoil and they were made 50 years ago way ahead of it's time. I worked on them.
Mantis dinghy is nothing new. The International Moth class has been doing this for the past 5-10 years now. BTW, Moth foilers make for some of the MOST erratic sailing and very entertaining spills 😂
@@tulahalpine6131 They are elevated above other boats and so become a decapitation machine in collisions and idiots don't tend to wear kill cords which leads to It going of at some insane speed and into swimmers or other vessels.
the reason why hydrofoil have virtually disappeared is that it can only operate on flat and still waters. See the video shows ONLY calm waters. 70% of video is animation btw
That's actually not entirely true. If anything hydrofoil vessels are better in choppy water. because lifting the craft out of the water helps minimise the effects of the weather and if it ends up being too rough you can just drop back down and use it like a standard boat. Actually Artemis recently used theirs to travel from Northern Ireland to Scotland.
Hydrofoil vessels can operate in choppy waters; they are actually much better than displacement hulls in these conditions, as they fly above the waves (eg Sydney Harbour hydrofoil ferry). They perform poorly in very rough conditions (big steep waves and deep ocean swells). Major reasons they have not succeeded has been the draft difficulties of the foils, and the power requirements for initial start off. Once on foils they are VERY low energy consumption, about 1/10th of regular boats' consumption. These newer foilers with pivoting foils solve the draft issue. The drag and power issue before take-off makes these most suitable for smaller craft, less so for harbour ferries, and unsuitable ever for commercial shipping and fishing vessels.
Imagine standing on a very thin stick, with both legs. That stick has to support ALL of your weight plus the weight of the vessel you're in. If your stick is not longer than the average wave-length, you strike water and possibly capsize. Aeronautic systems can correct themselves in a few hundred knots, a hydro-based system has FEET to correct the mistake before you and your passengers are breathing water. That said, I know it CAN be done, but don't know how to assemble the right cadre of minds to make it happen.

Love all of these crafts… why has this tech not become common place?
Very expensive to the people buy them.
Also much more dangerous in the hands of idiots.
Where is Candela?
@mistergum5130 why if I may ask?

Definitely the 'Foiler '.
Realy I like this amazing ships
Love them all my dream 🎉
Amazing
Saying the word ELECTRIC doesn't make something zero emissions, stop saying that

Not gonna Lie i build that ladt boat for artemis
Only one or two actually exist, the rest are prototypes or CGI
The Artemis EF-12 is on the market now.
The electric versions are a rich eco woke plaything. You are not going to save the environment with these craft.
why arnt all boats Hydrofoils?
