Before I posted a video of a hydrofoil sailing on the water, the whole ship is like flying on the water, after watching it, some netizens are very curious about how it is able to fly on the surface. Today, the boat people will share a few photos of the underwater structure of the hydrofoil, I believe that after you see it, you can understand the principle at once.
Hydrofoils on the Yangtze River
A small hydrofoil made by foreign cattlemen. Although the hydrofoils operating on the Yangtze River have been eliminated, I personally believe that in the field of play, hydrofoils still have good prospects.
Small hydrofoils
Let's first look at the way hydrofoils sail the Yangtze River.

Then look at the photo of it in the floating dock, and the bottom structure has been exposed.
Bottom structure of hydrofoils
If we zoom in locally, we can clearly see the hydrofoil structure at the bottom of the ship.

Is this a close-up of its thrusters, or is it a conventional propeller used as a propeller.
The propeller of a hydrofoil
After looking at its bottom structure, I believe you have understood. Hydrofoils use thrusters to propel the ship forward, and when the speed of the ship gradually increases, the buoyancy provided by the hydrofoil will lift the hull off the water, thereby greatly reducing the resistance of the water to increase the speed of navigation.
