What Is Hydrofoil?

A hydrofoil is basically a wing-like structure consisting of a flat or curved piece usually a metal plate that is equipped with an outboard motor of a boat or ship or attached to the hull.

While moving forward, the surface of the device reacts to the water it is passing through by causing it to flow downward. The downward flow of water is what produces an upward force, which raises the vehicle’s hull.

By raising the boat’s hull from water, the hydrofoil is able to reduce drag, which results in greater speed and efficiency.

The inventor of the hydrofoil is Alexander Graham Bell, who happens to be the person behind the invention of the telephone.

Does a Hydrofoil Really Work?

As earlier indicated, what a hydrofoil basically does is to enhance speed while reducing drag.
While a hydrofoil is a great addition to a vehicle’s outboard, it doesn’t always work in every situation.
What really determines whether a hydrofoil will work or not is your boat design.

Hydrofoils generally provide a performance boost for outboards. However, the impact may not always be felt.

Usually, the smaller the boat, the more likely the impact would be felt.

Thus, a small boat using a hydrofoil can increase its speed by 2-3 mph and significantly reduce its side to side rocking motion by 10 -15 percent.

SE Sport Hydrofoil Clip

If you don’t want to alter or scuff your cavitation plate, then opting for a hydrofoil with a no-drill mount is your best bet.

Unfortunately, no-drill mounts are notorious for falling off when traveling at high speeds or during moments of impact. And most times, this is connected to the type of mounting hardware used to secure the hydrofoil.

Thus, in order to get a secure installation, you need to use the right mounting hardware. For SE Sport hydrofoils (specifically SE 200 and SE 300), using any other clip besides the SE Sport Hydrofoil Clip will lead to an insecure mount.

The clip is made of high-quality material that is break-resistant. So, no matter how many times it falls, you don’t have to worry about breakage.

To further guarantee its resilience and durability, the clip is reinforced with fiberglass. The clip is made in the US, so you can rely on its quality.

It doesn’t take much time to install, and no drilling is required.


  • No drilling required
  • Break-resistant
  • Four-fold securing method
  • Highly durable


  • Takes a bit of time to install

Features to Consider Before Buying

In order to find the perfect hydrofoil for your engine, there are some key things you need to consider.

Boat Size

This is probably the most important thing to keep in mind when shopping for a hydrofoil. The size of your boat will determine whether a hydrofoil will be useful to you or not.

Hydrofoils are generally targeted towards small boats and are ineffective with the larger ones.
So, if you have something below 22ft, then a hydrofoil would be a good investment. However, for larger boats, it would probably not make any difference.

Compatibility with Motor

Another thing you should strictly consider is how compatible the hydrofoil is with your outboard motor.

In this case, you need to pay attention to motor HP. For optimum performance, you need to get a hydrofoil that meets the power requirement of your outboard.

Mounting Option

There are basically two mounting options available for hydrofoils – clamp-on and drill mount.
Drill mounts are the most common and tend to “stick” better. They usually require the cavitation plate to be drilled to set them up. The major advantage drill mount offers is that it ensures the hydrofoil always remains in place.

However, if you don’t like the idea of drilling your outboard, then you can opt for a clamp-on hydrofoil.

These units usually come with mounting hardware for clamping them to your outboard. The major disadvantage of using them is that they can fall off. This mostly occurs when moving at high speeds or during impacts.


Also, you need to consider the material type before making your final decision on a hydrofoil.
There are different materials used for making hydrofoils. The most common ones are plastic, aluminum, and stainless steel.

Plastics are hard and thus last longer and handle impacts well. Aluminum and stainless steel are also great. Stainless steel is better in terms of durability and weight; however, it’s usually more expensive.

Aluminum hydrofoils may feature an anodized finishing and other special materials to improve its durability and toughness.
