Enter the coefficient of lift, the hydrofoil velocity (m/s), and the hydrofoil wing area (m^2) into the Hydrofoil Lift Calculator. The calculator will evaluate the Hydrofoil Lift. 

Hydrofoil Lift Formula

The following formula is used to calculate the Hydrofoil Lift. 

HL = CL * (997*V^2/2) * A


  • HL is the Hydrofoil Lift (N)
  • CL is the coefficient of lift 
  • V is the hydrofoil velocity (m/s) 
  • A is the hydrofoil wing area (m^2) 

How to Calculate Hydrofoil Lift?

The following steps outline how to calculate the Hydrofoil Lift.

  1. First, determine the coefficient of lift.
  2. Next, determine the hydrofoil velocity (m/s). 
  3. Next, determine the hydrofoil wing area (m^2). 
  4. Next, gather the formula from above = HL = CL * (997*V^2/2) * A.
  5. Finally, calculate the Hydrofoil Lift.
  6. After inserting the variables and calculating the result, check your answer with the calculator above. 

Example Problem:

Use the following variables as an example problem to test your knowledge.

coefficient of lift = .45

hydrofoil velocity (m/s) = .35

hydrofoil wing area (m^2) = 2HL = CL * (997*V^2/2) * A =  ?
