The Skeg

In order to understand what a skeg guard is and its significance, it is important for us to learn about the skeg first. What does a skeg do on a boat motor and on watercraft?

How Skegs Work

The skeg’s function varies depending on the watercraft. For boats, the boat motor skeg serves as protection for the boat propeller and some rudders attach to the skeg, but it also affects stability.

Skeg Vs Rudder

While the rudder and skeg are both fin-like devices and both are found at the bottom of a watercraft’s stern, there are things that set them apart. First, their shape may differ in that rudders are more vertically elongated and may be narrower.

Skeg Guard

Now that we have a better understanding of the skeg, it’s time to turn our attention to the skeg guard. While the skeg serves to protect the propeller from damage, the skeg guard is used to protect the skeg from damage. But is it really necessary for us to protect the skeg in the first place?

Why Use a Skeg Guard

As mentioned above, the skeg is an extension of the keel and so is part of the watercraft itself. Because the skeg also helps keep the watercraft stable, any significant structural damage to the skeg may affect the watercraft’s performance. This is where problems come in.

How the Skeg Guard Works

The skeg guard is often made of a durable material such as stainless steel or aluminum, but you can also find other types such as a carbon fiber skeg protector, and some people even make their own homemade skeg guard. It is usually bolted onto the skeg and serves as a shield against anything that may cause damage.
