"Doel-Fin is the original hydrofoil developed by an aeronautical engineer to improve overall performance on all boats with outboard motors or outdrive units.
...
The positive effects include greater stability, consistent planing at lower RPM, faster out-of-the hole performance, better gas mileage, steadier turns, higher top-end speeds and lower bow rise at all speeds."

"It uses the same principle as airplane wings. Water flow over the wing creates lift in the stern and compensates for motor weight. Doel-Fin will "calm the boat down" in rough water and eliminate the bow-high position.
...
You can expect fuel savings from 10-50%, with the average being around 30%."

 

daquiri are you suggesting the products are similar? They don't seem at all alike in terms of the function.
