Hydrofoil is a foil, that operates in water. Hydrofoil are similar in appearance and purpose to aerofoils used in aeroplanes and drones. Boards that use hydrofoil technology are also simply named foilboards.
As a hydrofoil craft gains speed, the hydrofoils lift the board’s hull out of the water, decreasing drag and allowing greater speed.
How Hydrofoil works?
Since air and water are governed by similar fluid equations— But with different levels of viscosity, density, and compressibility. The hydrofoil and airfoil create lift in the same ways. The Hydrofoil shape moves smoothly through the water, deflecting the flow downward, which, following the fluid dynamics, cause an upward force on the foil. This turning of the water creates higher pressure on the bottom of the hydrofoil and reduced pressure on the top.
how to attach hydrofoil to surfing board?
There are many mounting solutions for Hydrofoils. But for foil boarding we need foil mounting with wide Hydrofoil adjustment range.
