Hydrofoil Stabilizers

Hydrofoil stabilizers, sometimes called hydrofoil fins or outboard stabilizers, are a rigid "wing" that bolts to the cavitation plate on outboard motors as well as some I/O engines. As the hydrofoil moves through the water, it acts like a wing, raising the back of the boat in the water. This helps boats improve their hole shot and maintain a plane at lower rpms, which can improve fuel economy. By raising the stern the trim is adjusted and the boat planes with the bow in a lower position, which increase visibility and safety.

How to Hydrofoil Stabilizers Work?

As the hydrofoil moves through the water, it acts like a wing, raising the back of the boat in the water. Hydrofoil stabilizers, sometimes called hydrofoil fins or outboard stabilizers, are a rigid "wing" that bolts to the cavitation plate on outboard motors as well as some I/O engines. This helps boats improve their hole shot and maintain a plane at lower rpms which can improve fuel economy. By raising the stern the trim is adjusted and the boat planes with the bow in a lower position, which increases visibility and safety. If you want to reach a plane more quickly, struggle keeping your boat on a plane, plane in a bow high attitude, experience porpoising or chine-walking, a hydrofoil stabilizer may offer some real performance improvements. The extent to which a hydrofoil will improve your boat's performance depends on your equipment and the conditions you typically boat in.
