How Long Should a Boat Trailer Tongue Be?

If you’re planning to buy a boat, one of the most important things to consider is the trailer tongue length. The tongue is the part of the trailer that connects it to your vehicle’s hitch. The length of the tongue determines how well your boat will sit on the trailer and how easy it will be to tow.

What is a Trailer Tongue?

Before we dive into how long a trailer tongue should be, let’s first define what it is. A trailer tongue is the part of the trailer that extends from the front of the frame and attaches to your vehicle’s hitch. It plays a crucial role in keeping your boat stable during transportation.

How Long Should a Boat Trailer Tongue Be?

The length of a boat trailer tongue depends on several factors, including the size and weight of your boat and where you plan on launching it. In general, experts recommend that the tongue should be around 10% to 15% of the total length of your boat.

For example, if you have a 20-foot boat, then your trailer tongue should be around 2 to 3 feet long. This will help ensure that your boat sits properly on the trailer and stays balanced during transportation.

Why is Trailer Tongue Length Important?

Having an appropriate-lengthed trailer tongue is important for several reasons:

– Stability: A proper-lengthed tongue helps distribute weight evenly on both axles, keeping your boat stable during transportation. – Maneuverability: If you have too short or too long of a tongue, it can affect how well you can maneuver while towing.

– Launching: If you plan on launching your boat in shallow waters or steep inclines, having an appropriate-lengthed tongue can make it easier for you to get into and out of water. – Safety: A poorly balanced load can cause accidents while driving.

Factors That Can Affect Trailer Tongue Length

Several factors can affect how long your boat trailer tongue should be. Here are some of the most important ones to consider:

– Boat weight: The heavier your boat is, the longer your tongue needs to be to maintain stability during transportation. – Trailer length: The length of your trailer can also affect how long your tongue should be.

Longer trailers may require longer tongues for proper balance. – Hitch type: Different hitch types require different lengths of the tongue. Make sure you choose the right hitch for your vehicle and boat.


The appropriate-lengthed trailer tongue is crucial for safe and stable towing of your boat. Before purchasing a trailer, make sure you consider all the factors that can affect how long it should be. By doing so, you’ll be able to transport your boat with confidence and ease.
