Try a simple "flat" wing(even flat it's still technically an airfoil). Just a flat board for wings, stabilizers and rudders. In RC airplane they got things called them foamies. They fly perfectly with no classic airfoil. Only dihedral angle(like v of a boat edge) and swept back angle really makes a difference in response and stability. The lifting of this hydrofoil wing is all in the angle of attack which you control with your leg and stance. All those complex curved surfaces affect "efficiency" and "drag" but with slow velocity it's not a big factor.
What you say is true however an aerofoil does 2 things. An aerofoil increases the range of angles and speeds for which the wing will not stall. Aerofoils also decrease drag ratios for wings, especially parasitic drag. ...Just be sure that the back of the foil is fairly sharp tapering. Cheers
@@TheSurfer446 people who complain about bad RU-vid video quality make me think, "THIS ISN'T WHAT I DIDN'T PAY FOR!" RU-vid creators get my respect for sharing the knowledge, period, end story, mad props.
@@TheSurfer446 The little kite that takes you out (and up on foil) in Surf... the new sport. wing surfing on foil board. Wng foiling. -Great job! -Cheers!!!
Would this foil also work when you try to pump it, not being pulled by the boat. Or would it work when mount it to my surfboard with the mast and sail?
