Doel-Fin® is the original hydrofoil developed by an aeronautical engineer to improve overall performance on all boats with outboard motors or outdrive units. Molded in two pieces of guaranteed unbreakable, high-strength plastic, each foil is designed to flex independently to absorb shock. 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. Doel-Fin is designed for use with small motors, big motors and inflatable dingies.

Personal Experience:
While cruising with a family of five, our 12' RIB with a 15 HP Yamaha outboard would plow like a bulldozer when we were all aboard with a full load of provisions. This not only uses more fuel and takes longer, but is also less safe. Once we installed our Doel-Fin®, our RIB would plane quickly and easily. It also made a tank of ga$ last a long time!
