What is the bottom of a boat called?
Boats and ships are one of the lesser explored means of transport. While many people might use them for recreational activity but still, they are objects of intrigue. Most individuals are not even familiar with how a boat or ship operates, let alone the parts of the boat. Today, we will help you understand more about them.
Did you know that the bottom of the boat has an actual name? Most people are not aware of these facts. Today, we will focus our attention on what is the bottom of a boat called?
We will also help you know about different types of boat bottoms which you can come across.
What is the bottom of a boat called?
The bottom of the boat is called hull. It is the part which directly comes in contact with the water. Hull can again be divided into two parts, which are the bow and stern. The bow is the front part of the hull while the stern is the rear part.
The design of the hull can vary from one boat to other. There are different types of the hull which we will go into the details below. The design depends on the boat type, the displacement and the weight which it has to carry.
It also depends on the speed at which it has to travel. Nonetheless, instead of just thinking that hull has a single design or a shape, you have to look at the hull types which we will discuss below and then you can understand about the design and different types in greater detail.
Types of boat hulls
We will now share with you different hulls so that you can understand more about their design. These different types are chosen according to the boat.
1. V-shape Hull:
The V-shape Hull, as the name itself suggests, resembles the shape of a V. The advantage of this hull is that it can easily cut through the waves. It is suitable for boats which encounter rough weather.
The disadvantage; however of this hull is that it provides less inner space. However, since it can cut through the waves, you can travel at a higher speed, which is an advantage when using commercial boats.
2. Pontoon Hull:
Pontoon Hulls consists of pontoons which can keep the boat afloat. The main advantage of this type of hull is that it provides you with a larger surface area and is comparatively stable. It is however perfect for boats which travel only a smaller distance.
If you want to stabilize your boat, it is one of the best of all types which you can go with. It is easy to maneuver but not suitable for traveling at high speeds. If you want to relax in the water and travel only for a short distance in your boat, you can certainly go with this type of hull.
It is high on stability but has moderate speed.
3. Displacement Hull:
Displacement hull is perfectly suitable for larger vessels. It can help boats and ships travel in rough waters. It is ideal for transport and commercial ships.
Even though the displacement is slow, but it can push through the water. It is one of the primary reasons why it is suitable for high-displacement vessels.
4. Round Bottom Hull:
Round bottom hulls can help you travel at high speed. However, they can do so at the loss of stability. They can make the turn in the waves.
That is why; you can deviate from your set the path to a certain extent. Often, the stability is on the lower side. That is why; when embarking or alighting from the boat, it is essential to be careful.
They are often used in sailboats and canoes to help them travel at a decent speed.
5. Flat Hull:
Flat hulls are suitable for moving at slower speeds. They are perfect for calm water bodies rather than seas or rough rivers. They are not that stable in harsh waters.
Often, the flat bottom hulls are ideal in smaller boats. It is because the water resistance is on the higher side for the larger ships; such a hull requires a lot of power to displace an equivalent amount of water. That is the reason why you will find these hulls only on smaller boats.
6. Deep V Hull:
The Deep V Hull is often suitable in power boats. It allows them to move at a higher speed. Also, due to the deep V, stability is higher as well.
It means that even at high speed, they can negotiate with rough water, which is what makes them so unique. You won’t find these types of hulls on larger boats since they won’t provide the same amount of speed to the larger ones. They are almost always exclusive to the small boats and power boats.
7. Multi-Chine Hull:
Multi-Chine Hulls are often suitable in catamarans. They are cross between pontoon hulls and V-shaped hulls. They provide stability and can help the boat travel at a higher speed than the pontoon boats.
However, this can happen only at the cost of maneuverability. You cannot make a quick turn when you’re on a boat having this type of hull. You can travel at a reasonably good speed and can get high stability, but fast turning is not the forte of this hull.
8. Tunnel Hull:
Tunnel hulls as the name itself suggest it consists of protruding edges with the middle part a bit higher. These also are often popular for fishing boats. Even though they make the ride a bit rough, but they can certainly increase the speed at which you can move. It is one of the primary reasons why they are popular in fishing boats.
They are perfect for providing you with stability when you’re stationary. It means that once you get into the fishing zone, you can stay there for hours together until you get your catch.
These are a different type of hulls which you can come across various types of boats. As you can see, each type has a specialty. That is why; you will only find it on a particular boat where it serves the purpose.
The different kind of hulls can provide you with various advantages like speed, stability, and displacement. Depending on these factors, different boats have different hulls.
Materials used in the construction of boat hulls
These days, boat manufacturing has become a large scale industry. Due to this very reason; hundreds of boats are being manufactured simultaneously on the assembly line. Most of the boat manufacturers choose from only four materials when it comes to building the boat hull.
We will help you know more about these materials below.
1. Steel:
Steel is one of the most popular materials to manufacture boat hulls. It is in use for almost a century. It is not only suitable for the boat hull but also the construction of the boat as a whole.
There are quite a few properties in steel which make it ideal as compared to the other options. It is durable, has high tensile strength, and is depression resistant. The cost of steel is on the lower side when purchased in bulk.
It is one of the main reasons why steel is suitable for making hulls. However, these days, some of the composite materials are replacing steel as they are comparatively lighter. When it comes to sustainability, it is one of the best options to manufacture the hull.
2. Aluminum:
The reason why aluminum has become so popular while manufacturing the boat hull is that it is light-weight when you compare it with steel. It is highly seaworthy as well and provides you with a stable ride. At the same time, it can easily withstand the pressure of traveling at a faster speed.
When you compare the mileage of the boat, which uses steel and the one uses aluminum, you will realize that the aluminum boat can provide you with better mileage.
With the help of corrosion resistance and chemical resistance, you can be sure that the hulls will last for a long time. The only bit of the problem is that aluminum is expensive than steel. It does not have the same oppression resistance, as well.
Due to this very reason, aluminum hulls are often painted with the lead paint to make them more sustainable.
3. Fiber reinforced plastic:
Fiber reinforced plastic is an example of a composite material. It has recently become quite famous. There are numerous advantages of fiber reinforced plastic.
Some of these advantages include durability, high tensile strength, light-weight, corrosion resistant. It can help the boat travel at high speed. It is not just used for commercial and personal boats but also military ones.
It is a substitute for wood and steel and in the maritime industry. It is entirely recyclable, which is another advantage.
4. Polyethylene:
Polyethylene has applications in fishing boats, amateur boats, surveillance, and even security boats. The high-density structure has a high strength to density ratio. It is impact resistance and low maintenance.
The high buoyancy makes it perfect for constructing boats and hulls. It is easy to mold, which ensures that you can build the hull of any shape and type with this material. However, it has a limited lifespan.
It also cannot withstand high temperature. These two are drawbacks of polyethylene. However, since it is recyclable and also increases the mileage of the boat.
The absence of hull paint makes it light-weight, which is why it maritime industry uses polyethylene as well. These are the four materials used for making the hull. Each one of them has its pros and cons.
So, if you up until now have been wondering what is the bottom of a boat called? The answer is hull. Hulls can be of different types, and the construction of hull uses a variety of materials as well.
That is why; the whole design and manufacturing in itself forms a significant part of the boat manufacturing industry.
What is the top of a boat called?
The top of a boat is called the “deck.” The deck is the uppermost surface of the boat that provides a platform for people to stand on. The deck is a fundamental part of a boat, providing a stable and flat surface for people to walk, stand, and work on.
It is usually the topmost part of the boat and is separated from the hull, which is the lower part of the boat that sits in the water.
The design and layout of the deck can vary greatly depending on the type of boat. For example, sailboats typically have a large open deck area with a mast and rigging for sails, while powerboats may have a smaller deck area with a helm station and seating for passengers. Some boats may have multiple levels of decks, such as a flybridge on top of the main deck, which provides additional seating and visibility for the captain.
The deck may also be used for various activities, such as sunbathing, fishing, or dining. On larger boats, the deck may have separate areas for different activities, such as a dining area, a lounging area, and a swimming platform at the stern.
In addition to providing a platform for people to stand on, the deck may also house various equipment and structures necessary for navigation and communication. This can include items such as GPS, radar, radio antennas, and navigation lights.
Overall, the deck is an essential part of a boat, providing not only a functional workspace but also a place for relaxation and enjoyment on the water.
What are the four sides of a boat called?
The four sides of a boat are called the bow (front), stern (rear), port (left), and starboard (right).
The term “bow” comes from the Old English word “bog,” meaning shoulder, and refers to the front of the boat, which is often pointed and shaped like a shoulder. The term “stern” comes from the Old Norse word “stjorn,” meaning steering or rudder, and refers to the back of the boat, where the steering mechanism is usually located.
The terms “port” and “starboard” are a bit more complicated. Historically, sailors referred to the left side of the boat as the “port” side because that was the side that faced the dock when the boat was moored. The right side was called the “starboard” side because it was the side from which the steering oar (or “starboard”) was used to steer the boat.
Over time, these terms became standardized and are now used universally to refer to the left and right sides of a boat, respectively.

Conclusion
The bottom of the boat is called the hull. The hull is the main body of the boat that sits in the water, and it is designed to provide buoyancy and stability to the vessel. The hull may be shaped differently depending on the type of boat, with some being flat-bottomed and others being V-shaped or rounded.
The top of the boat is called the deck. The deck is the upper surface of the boat that provides a platform for passengers and crew to stand on. It can also house various structures such as the cabin, cockpit, and other equipment needed for navigation and communication.
The four sides of a boat are called the bow (front), stern (rear), port (left), and starboard (right). These terms are used to describe the sides of the boat when it is in the water.
It is worth noting that the terms “bottom” and “top” are not usually used to describe the sides of a boat. Instead, the terms “port” and “starboard” are used to describe the left and right sides, respectively, when facing toward the bow.
