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 2 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, steadier turns, higher top-end speeds and lower bow rise at all speeds.
• Doel-Fin® improves overall performance - even on boats with well designed hulls
• Save up to 30% on fuel consumption
• Faster out-of-the-hole for happier water skiers
• Maintain lower planing speeds without constant throttle adjustment
for wakeboarding, tubing or beginner skiers
• Less bow rise for better visibility and increased safety
• Simple 15-minute installation; hardware included
