What’s a hydrofoil stabilizer?

A hydrofoil stabilizer lifts the stern of a boat, helping it get on the plane and stay level at slower speeds. It improves fuel economy, maneuverability, and driver vision, and can prevent porpoising. It is easy to install and does not affect outboard maneuverability or fuel economy.

A hydrofoil stabilizer is a device attached to an outboard motor or in/out of the boat to help the boat get on the plane or level. The vessel is also helped to stay on the plane at slower speeds through the use of a hydrofoil stabilizer. Acting like an airplane wing, the stabilizer lifts the stern of the boat as it travels through the water, pushing the engine up and out of the water, bringing the boat up the plane a much shorter distance. than a hydrofoil boat equipped with stabilizer. Beyond a performance aid, the stabilizer is also a safety feature and improves driver vision by allowing the boat to operate with the bow in a lower position, which aids operator vision over the bow of the boat. ship.

As a boat travels through the water at low speed, the bow is usually high in the air with the stern very low in the water. This causes the boat to use a large amount of fuel as it pushes a large flat area of ​​the hull through the water. As the engine speed increases, the stern is pushed up and the boat begins to flatten or fly. The hydrofoil stabilizer helps raise the rear of the boat and shortens the time it takes to get the boat airborne. Once on the plane, the boat glides through the water much easier and is much easier for most people to maneuver.

For many boats, the ability to stay on the plane at slow speeds is greatly improved by the addition of a hydrofoil stabilizer to the lower engine unit. Commonly bolted to the engine’s cavitation plate, the hydrofoil stabilizer does not affect the outboard’s maneuverability and does not reduce fuel economy for most engines. The hydrofoil stabilizer actually improves the fuel economy of most boats because the boat more easily approaches and stays on the plane at slower speeds. Most boat owners install the typical stabilizer in a matter of minutes using only small hand tools.

On many outboard-equipped boats, the boat undergoes a series of rising and diving actions called porpoises. This is often caused by using an outboard motor that is on the verge of being too small to adequately propel the boat into the plane. By installing a hydrofoil stabilizer, the boat will often arrive by plane without the climb and descent characteristics associated with a small engine.
