Surfboard Construction: The Basics

Surfboards are a surfer’s trusty companion, taking them on wild adventures and thrilling rides. But have you ever wondered how they are made? At its core, surfboard construction involves shaping a foam blank into the desired form, adding a fiberglass layer, and applying a resin coating. The foam blank is shaped by hand or machine to create a custom design, and then the fiberglass cloth is added while the resin coating is applied to help harden and protect it. There are various materials and techniques used in surfboard construction, and each one has its unique pros and cons. Whether you’re a curious beginner or a seasoned pro, understanding the basics of surfboard construction can take your surfing experience to the next level!

Surfboard Construction: The Basics

Surfing is more than just a sport, it’s a lifestyle. Every surfer has their own unique style and preferences when it comes to their surfboard. Whether you are a beginner or a seasoned pro, understanding the basics of surfboard construction can help you pick the perfect board for your needs. In this post, we’ll go over everything you need to know about the materials, techniques, and designs used in surfboard construction.

The Foam Blank:

The first and most important part of a surfboard is the foam blank. The foam used in blanks is typically made of polyurethane, expanded polystyrene, or extruded polystyrene. The foam is shaped using either hand tools or automated machines, such as computer-aided shaping machines. Experienced shapers often use hand tools to make minor adjustments while creating a board.

Once the foam blank is shaped, it’s given a fiberglass coating that helps protect the foam from water and adds durability. When selecting a foam blank, it’s important to consider the type of surfing you plan to do, as well as your experience level. Thicker and wider foam blanks are generally better for beginners, while thinner ones are suitable for advanced surfers.

The Fiberglass Layer:

The second layer of a surfboard is the fiberglass. Fiberglass is a type of woven cloth that is laminated to the foam to give it added strength and stiffness. A typical surfboard has one to two layers of fiberglass cloth, which is laminated onto the foam core with polyester or epoxy resin.

The weave pattern of the fiberglass determines how rigid the board is. A tighter weave pattern makes for a stiffer board, while a looser pattern adds some flex. The amount of fiberglass used can affect how heavy the board is, with more fiberglass adding weight to the final product.

The Resin Coat:

The final layer of a surfboard is the resin coat. Resin is used to seal and protect the fiberglass and foam, preventing water from getting inside the board. The two most commonly used types of resin are polyester and epoxy. Polyester is the more traditional choice and is commonly used on cheaper boards, but it has a lower tensile strength than epoxy. Epoxy is a stronger and more durable resin, which is why it is commonly used on high-performance surfboards. Boards made with epoxy resin are lighter but typically cost more money than those made with polyester resin.

Types of Surfboards:

Now that we’ve covered the basics of surfboard construction, let’s dive into the different types of surfboards on the market.


Shortboards are the most popular type of surfboard, commonly used by experienced surfers for their maneuverability and speed. They are typically around 6-7 feet long and have a narrow nose and tail, making them optimal for performing tight turns and tricks. Shortboards have a flat rocker, which reduces drag and increases speed but can make them harder to balance on.


Longboards, also known as Malibu boards, are the oldest type of surfboard and are often used by beginner surfers. They are typically between 8-11 feet long and have a wide, round nose and tail. Longboards have a greater volume than other surfboards, which makes them easier to balance on and ride waves. They also have a gentle, curved rocker that makes them easier to control.


Funboards are a hybrid between shortboards and longboards, combining the best of both worlds. They are typically between 7-8 feet long and have wider noses and tails than shortboards, making them easier to catch waves on. They also have a flatter rocker than longboards, allowing them to pick up speed and be more maneuverable. Funboards are a great option for beginner to intermediate-level surfers who want more stability than a shortboard but more maneuverability than a longboard.


Fishboards, as their name suggests, have a fish-like shape with a wider nose and tail than a shortboard. They are a great option for smaller waves because they generate more speed with less power. They are typically between 5-7 feet long and have more volume than a traditional shortboard, which makes them easier to ride. Fishboards are popular with surfers who want quicker turns and a more playful ride.

Wrapping Up:

Now that you have a better understanding of how surfboards are made, you can make an informed decision about which board will work best for you. Before purchasing a new board, consider your experience level, the type of surfing you plan to do, and what size board will work best for you. Keep in mind that used surfboards for sale can be a great option if you’re on a budget or just starting out. Happy shredding!

Choosing the Right Surfboard Design

Not all surfboards are created equal. Design plays a huge role in the functionality and performance of a surfboard. The three main design factors to consider are the rocker, the rails, and the tail. The rocker is the curve along the bottom of the board from nose to tail. A high-rocker board is great for steeper waves because it can maneuver more easily. A low-rocker board is ideal for flatter waves because it can go faster with less drag. The rails are the edges of the board, and they can be sharp or round. Sharp rails provide better maneuvering in steeper waves, while round rails are ideal for catching waves more smoothly. Finally, the tail is the back end of the board, and it can be wide or narrow. A narrow tail allows for tighter turns and better maneuvering, while a wider tail provides more stability and balance. Keep these factors in mind when selecting your perfect surfboard.

Caring for Your Surfboard

Once you’ve purchased your surfboard, it’s important to care for it properly to ensure it has a long life. Rinse your board with fresh water after every use to remove salt buildup. Store it in a cool, dry place to prevent damage from the elements. Avoid leaving it in direct sunlight for extended periods because it can cause the foam to deteriorate over time. Also, consider investing in a surfboard bag to protect it during transport. With proper care, your surfboard can last for years.


Surfboard construction is fascinating, but the most important thing is that you enjoy the ride. Whether you’re a veteran surfer or a beginner, there’s nothing like catching a wave and feeling the thrill of the ride. Keep in mind all the detailed information covered in this post when choosing your next surfboard or taking care of your current one. With a little bit of knowledge, you can make sure you choose the right surfboard for your needs, and that it will last for many amazing surf adventures to come. Happy surfing!

FAQs About Surfboard Construction

Here are some commonly asked questions about surfboard construction:

1. How long does it take to shape a surfboard?

Shaping a surfboard can take anywhere from a few hours to several days, depending on the complexity of the design and the experience of the shaper. It can take even longer if the board needs multiple layers of fiberglass or if it’s being painted.

2. What are the benefits of using epoxy resin over polyester resin?

Epoxy resin is stronger, more durable, and has a higher tensile strength than polyester resin, which is why it’s preferred by many surfers for high-performance boards. Additionally, epoxy provides a lighter finish. However, because of its cost and performance advantages, epoxy resin is more expensive than polyester resin.

3. Can beginners ride shortboards?

While shortboards are typically used by experienced surfers, beginners can also ride them. It’s important to select a board with enough volume and width that will provide more stability and make balancing easier for the beginner surfer.

4. What is the best material for a surfboard to be made of?

The most common material for surfboards is polyurethane foam or an extruded polystyrene (EPS) foam core. For the fiberglass, polyester and epoxy resins are the two most commonly used materials. The best material for a surfboard depends on the surfer’s desires, preferences and surfing level.

5. How can I tell if a used surfboard is in good condition?

Before purchasing a used surfboard, examine it for any visible dings, cracks or obvious signs of damage. If possible, feel the board, if you can feel any soft spots or see any signs of water damage, it may indicate that water has entered the foam core. Also, make sure the fin boxes aren’t damaged and the fins fit securely. You can always ask the seller for more information or photos if needed.

6. How do I know what size board is right for me?

The right size board depends on your experience level, weight, and the type of waves you want to surf. A good rule of thumb is to select a board that is 6-12 inches taller than your height.
