Whether you have a boat, are interested in a boat, or like to go out on boats, you have likely heard the term “beam.” This term often comes up when looking at the specifications of a boat or when people are comparing two types of boats.
The beam can influence the decision someone makes when they are trying to decide between two different models. But, if you do not know what this term means, you may not know just what significance or relevance it has.
So, what exactly is the boat beam? And why does it matter so much?
Well, let’s take a look.
What Is Your Boat’s Beam?
The beam of a boat is its widest point, measured from one side to the other and perpendicular to the centerline. To visualize this, imagine looking directly down at your boat from above; the beam is the distance across its broadest part. It’s different from the boat’s length, which is another measurement entirely. The beam is crucial because it influences the boat’s space, stability, and handling, which is why boaters often discuss their beam sizes.
Measure the Beam of My Boat
If you still have the specifications of your boat, you will find the beam’s measurement there; however, if you do not, you can measure your boat’s beam relatively easily.
To start, you will what to locate the widest portion of your boat’s hull. Your boat must be on a level surface to get the most accurate view and measurement possible. Once you are ready, simply take a measuring tape and measure the beam.
Why Does the Boat’s Beam Matter?
Okay, you now know what the beam is and how to measure it, but why does it even matter?
Balance and Stability
One of main reasons for the beam is to provide balance and stability for your boat. A wider beam is going to provide you with the best stability as it works to lower the center of gravity. It also spreads the weight of the boat out more evenly thus allowing your boat to float balanced on the water.
Having a beam that is wider is beneficial in that it means your boat is less likely to roll or tip over, even in rough water conditions. Many people prefer a wider beam as it allows them to feel safer while they are out on the water.
With that said, narrow beams have their place too. While they are going to be more prone to rolling or tipping over, boats with narrow beams are faster and more streamlined.
Performance and Handling
We have already established that your boat’s beam helps to stabilize and balance your boat. It also plays a critical role in your boat’s performance and handling. Boats that sport a wider beam are much more stable on the water which makes them easier to handle, something that is beneficial for new boaters.
Boats with narrow beams may not feel as stable and they are not recommended for new boaters; however, they are ideal for those who are after a boat that offers speed. Racing boats use narrow beams to ensure they are fast on the water.
Space and Comfort
When it comes to size, it does matter, and the size of your boat’s beam will dictate how much space you have on your boat. A wider beam lends itself to more room on deck and in the cockpit. Wider beams are excellent as they offer more comfort and space for both passengers and equipment.
If you have a family or you plan to spend a lot of time out on the water, a wider beam boat is going to provide you with the ability to feel relaxed and comfortable the entire time.
Narrower beams are not going to provide roomy and comfortable space but that is not to say the chairs and such on the boat are not comfortable – you will just be limited in space.
Maneuverability
When it comes to maneuverability, your boat’s beam will affect the way your boat moves out on the open water and when you go to dock. A wide beam can make it a challenge to move around, especially if you are in a narrow area or you are trying to dock with limited space.
Additionally, your boat’s beam influences the turning radius of your boat. A wider beam will need more room to turn as opposed to a narrow beam.
When it comes to maneuverability, the choice between a narrow or wide beam will depend on your preferences and where you will be using your boat.
Final Thoughts
Now that you know more about your boat’s beam, you can see why it matters. If you are in the market for a boat, the size of the beam will matter, and your boat’s beam will determine your experience on the water as well. If you are unsure of which beam would best suit you, test out one of each and see which one you feel most comfortable with. Once you consider your needs, you will find that choosing a beam size is easy.
