The jet fin you show is a stepped/offset design with vents between the 2 surfaces to allow water to pass through on the back stroke to reduce drag/resistance. The spoiler on the aircraft wing you show is extending a surface out (at a very diffent angle than the rest of the wing) into the airflow over the wing to disrupt it and add drag to slow the plane - there is no venting, so really apples and oranges...
I'd also love to understand how you claim to have created a surface (a wing) that you move through the water without creating any drag?
@Bob Evans you answered your own question with regards to the bias on this board. Frog kicking is the predominant kick used by most people that contribute to this board. Wish you had something that worked for that
This is a popular misconception of how an airplane flies, and it is not true.The wing of the aircraft is not providing a propulsive force...the speed differential of airflow above and below the wing creates lift not propulsion...the extension of the wing surface area creates high speed and resultant lower pressure of the laminar air flow above the wing which increases the amount of lift produced while the aircraft is traveling at a slower speed.
This is a popular misconception of how an airplane flies, and it is not true.

Fins definitely work in a different way than airplane wings! And paddle fins s work differently than split fins as well!
