What are the different types of surfboard fins?
How fins affect a surfboard? HEIGHT / DEPTH The taller the fin, the more hold it will have in the water, providing the rider more control. While shorter fins don't grip the water as well, they do allow the board to slide-out a little, which some surfers enjoy. Click to see full answer. In this way, what do Fins do for a surfboard?
What are surfboard fins called?
The degree of surfboard rake or surfboard sweep determines whether you have a looser feeling in your fins or you get more pivot out of them. Fin Foil The fin foil is an aerodynamic shape from front to back of the fin. Much like the wings on a plane, this foil generates lift under the board.
Why does surfboard have fins?
Fins are important because they are the device that gives you stability, control and direction on your surfboard. They help you maintain your speed and “cut” through the water, in a way that would be impossible on a finless board. There are many different fin set-ups.
Do surfboard fins really matter?
The size of the fin is going to impact your performance. A larger fin generally will have more hold and also provide plenty of control in bigger surf. A smaller fin, on the other hand, is going to be more forgiving and loose but you're going to sacrifice a lot of drive and control in bigger surf.
What does more fins do for a surfboard?
Fin Size: Bigger fins equal more hold, as more surface area is in contact with the water. Smaller ones create a “looser” feel. Fin Flexibility: Stiffer fins provide quick response but are less forgiving. Fin Base: This is the length of the fin at the part where it meets the board.
What does 5 fins do for a surfboard?
Five fin set ups feature two rail fin boxes and one center fin box – depending on the board, you might fin all Futures or all FCS boxes or Futures/FCS on the side with a single fin box in the middle. For most boards, the five-fin setup allows you to swap between a thruster and and quad set up.
Do larger fins generate more speed?
This is a fin performance measuring system that Futures uses to make the tech easier to understand. The larger the number, the more speed the fin generates.May 24, 2017
How many fins should a beginner surfer have?
2 Plus 1 Fins: The Stable Glider. Riding a single fin with two side fins is called a "2+1" setup. This configuration creates more stability for beginners while allowing a more experienced surfer to create speed where a single fin alone cannot. This is the ideal fin cluster for a beginner surfer.Feb 24, 2020
Is it better to have 3 or 4 fins on a rocket?
Three fins are best when designing a high performance, low drag rocket. This allows interference drag (drag caused by interference of the airflow over the body and fins at the junction) to be reduced by 25 percent.Aug 26, 2001
How many fins should a surfboard have?
Nowadays, 3 fins is the most common configuration and can be found on a variety of surfboard shapes and sizes. The two outer fins are closer to the middle of the board, angled towards the board center (“toed-in”) and can be flat on the inside in order to increase water tracking and speed.
What size fins should I ride?
How to size single fins? It is best to size your single / longboard fin relative to your board size. A generally accepted rule of thumb is to use the same size fin (in inches) as the length of your board (In feet) so for a 9ft board you would use a 9ft single fin.May 12, 2021
Whats the difference between 1 fin and 3 fins on a surfboard?
There are differences between thrusters and single fins. Single fins are for more down the line surfing, arcing turns and speed generated from the wave itself through positioning on the surfboard. Thrusters are easier in many respects, that's why they are so popular.Aug 16, 2020
What makes a surfboard a fish?
The shape of a typical fish surfboard is meant to give an intermediate rider a much more pleasurable experience on waves that are generally small and not all that thrilling. The wide and flat bottom makes it much more stable than a shortboard. It is also thicker and has more volume which adds to the stability.Jul 27, 2020
Do fins help catch waves?
Our Fins Look Like Modern Airplane Wings and Boat Keels Surfing (and SUP) is all about speed and control, catching lots of waves, and having long surf or paddling sessions before tiring out. We designed our fins to help people catch more waves, maneuver better, and have longer surf sessions.
What gives a surfboard drive?
Drive is said to how much the fins help you accelerate out of turns if you put enough pressure on them against the water. While fins by definition will produce drag for a surfboard going straight, the water surging against a fin in mid turn will produce a feeling of acceleration. This is known as drive.
How much do surfboard fins affect performance?
Some people even claim that your choice in Surfboard Fins can impact up to 40% of your performance.
What does it mean when your fins are bigger?
If the cant of your fin is larger, your going to gain a little more of that responsiveness through your turns. It means you can maintain some more drive when your board is tilted on the rail. More Fin Cant means your fins are angled outward in relation to the bottom of your surfboard.
What is a fiberglass fin?
These fins are strong. Although the thinner you sand them back the more they will flex. For shortboards the size of the fins means they are usually quite stiff. A stiff fin is the go-to for powerful waves when you want control and stability.
What does it mean when you look at the fin rake?
When you’re looking at the arc of the fin and how far back it tilts or sweeps, you’re looking at the fin rake. The larger the degree of rake, the more drawn out your turns will be. This is great for those bigger days with a nice long wall to work with. Less fin rake and a more upright fin template, means that you’re going to get some more pivot out of them – great on junkier, weaker days.
What is a cant on a surfboard?
Fin Cant is the degree of outward angle a fin has in relation to the bottom of your surfboard. If a fin has zero cant it’s position straight up and down at a right angle to your board. This is going to be fast in a straight line, but it won’t give you as much responsiveness through turns. If the cant of your fin is larger, your going to gain a little more of that responsiveness through your turns. It means you can maintain some more drive when your board is tilted on the rail.
What is the fin depth of a board?
Fin Depth. The fin depth or fin height refers to just how far the fin extends away for the bottom of the board. A deeper fin in the water is going to have more hold and stability than a shallow fin. The more shallow a fin, you are going to get more release when you throw that tail around through turns.
What is the fin base called?
The part of the fin that is actually attached to the board is called the base of the fin or the fin base. A longer (or wider) fin base is going to help with your drive. This translates into drawn out turns. Compare this with a narrow, or short fin base that is going to let you turn a little easier and sharper but without as much of that drive.
What is a single fin surfboard?
Single Fin. Single fins are most commonly found on longboards. The original fin set up is considered outdated by some, but it is still appreciated by others because it brings a different feel while riding the wave. They are usually long and wide, big enough to provide control over the surfboard on its own.
Why are fins important?
Fins are important because they are the device that gives you stability, control and direction on your surfboard. They help you maintain your speed and “cut” through the water, in a way that would be impossible on a finless board. There are many different fin set-ups.
Why do surfers use quads?
This helps surfers generate speed, even in weak waves, and helps to do quick turns, a bit like with a twin fin would, but with extra control. Surfers also use quads in big hollow waves, with the back fins placed further back on the board, for extra hold in steep waves.
Why are single fins good?
Provides good speed, as fewer fins creates less drag. Single fins are great for smooth, slow turns. The size of the single fin can help to prevent spinning out in the tube.
What is the most popular fin set up for surfers?
Thruster Fin. This is currently the most popular fin set up for most surfers, from beginners to experts. Frustrated with the fact that twin fins wouldn’t “hold” enough in bigger waves, Australian Simon Anderson came up with the idea of a three equal-sized fin set-up in 1980.
What does a small fin base do?
A small fin base will generate less drive but will provide quick and short turn arcs. Fin Rake or Sweep: Fin rake means how far the fin goes backwards (the way it tilts to the back). Less rake means it’s easier to pivot quickly, and more rake will create longer, more drawn out turns.
What is a sweep on a surfboard?
These are just a few of the many different fin characteristics. Another crucial element to consider is the surfboard’s tail shape, as it works in harmony with the fins to create a particular response, hold and control in the water.
What effect do surfboard fins have on a surfboard?
Surfboard fins have a huge effect on how your surfboard performs. Even the slightest changes in fin design can make a world of difference. If you’ve ever broken a fin and continued surfing or swapped the fins on your favorite board, you’ve probably already got a sense for it.
How do fins affect turning?
Fins set closer together or further apart will affect turning and drive, as will fins set closer or further from the back end of the board. You’ll also find that fin configuration will change how your boards feel. A single fin feels much different from a quad.
What is recoil fin?
Recoil refers to how quickly or slowly it takes for a fin to return to its original position. As some general rules of thumb, a more flexible fin is good for long, drawn out carves and turns, while a stiffer fin is generally good for quicker maneuvers and speed.
What is the fin base on a surfboard?
The fin base is the portion of your surf fin that is connected to the bottom of the board. In other words, it’s the bottom most portion of the fin that’s in the water. A longer base gives you more drive, hold, and more drawn out turns.
What is an asymmetrical surf fin?
Asymmetrical surf fins, which can be flat on one side or have a different foil ratio on each side (e.g. 80/20, 70/30, inside foil, etc.), are often found on the side/front fins on thrusters and quads. A fin’s foil controls the board’s lift and drag forces as water moves over the bottom of the board.
What does it mean when your fin is too fast?
A fin that’s too slow to recoil or hard to flex may feel sluggish and sticky , while a fin that’s too fast may feel like you’re surfing a step behind your board out of turns.
What is a fin cant?
Fin cant refers to the angle at which the fin leans relative to the bottom, perpendicular surface of the board. More cant is associated with more turning control, but increases drag. Less cant, or a fin that sits more upright, will produce more speed and drive with less turning control.
Glassed-In vs Swappable (Removable) Fins
Glassed-in fins are laminated into the surfboard. As you might imagine, a glassed-in fin might be smoother and sounder than a removable fin. However, glassed-in fins are difficult to repair and do not offer you the versatility of removable fins.
Box Types & Compatibility
Although longboard fin boxes are generally cross-compatible across all boards, the rest of the fin boxes out there are almost certainly equipped with one of these three box types:
Choosing Your Fins
When choosing fins for your surfboard, you should start with your weight. Choosing the appropriate fin size is the first essential step to choosing the right fins. Once you have decided on a size, examine your board's fin configuration, or fin setup. Your board will be outfitted with 1 to 5 fin boxes.
Fin Size
The following chart is evo’s recommended fin size according to rider weight. If you are in between sizes, consider the type of board or type of waves you will be riding with that particular setup. For example, if you are in between size M and L, you might pick size M fins for your small wave board, but size L fins for your big wave board.
Fin Configuration
Once you’ve decided on your fin size, you need to understand your board's fin configuration. To determine your fin configuration, examine the base of your surfboard near the tail. The number of fin boxes you see is the fin configuration and will likely range from 1-5. The most common surfboard fin setups are Single, Twin, Thruster and Quad.
Fin Dimensions and Geometry
The Sweep, Toe, Base Length, Foil, Flex, Height, and Cant are important measurements of every surfboard fin, and should be considered when choosing your next surf fins.
Conclusion
So what kind of fin is best for you? The best way know what fin is best for you and the waves you surf is to try different sets. Just like test driving a car, you should test drive fins in a variety of configurations and types.

What are the pros and cons of single fin?
The advantage of a single fin system is definitely the speed they produce, fewer fins create less drag, they offer a more laid back ride with a smooth, slow turning performance, the larger size also prevents spinning out in tubes, and nose riding.
What is a thruster setup?
A thruster setup uses three equal sized fins with the two outer fins being more forward, and the center fin is more to the rear of the board.
What is a 2+1 fin?
Using a traditional thruster setup but with a slight difference, a 2+1 fin setup has a larger center fin, where a thruster setup has three equal sized fins, a 2+1 has two smaller rail fins or otherwise known as "sidebites", and larger central fin.
What is a 2+1 on a longboard?
The sidebites offer greater lift, control, and stability to the board when it's on the rail, typically a 2+1 won't be used for a shortboard or fish, but for longboards giving you a better option than a single fin. Ideal Conditions: Small to medium size waves on the clear or choppy surf.
What is single fin setup?
Single Fin Setup. Now, these are traditionally found on longboards, but it's not unseen on shortboards. The single fin system is seen as outdated by some as newer analysis comes out it's evident that there are certainly better options, but they do certainly serve their purpose. Single fins can be found in both a glass-on setup, ...
When did twin fins become popular?
Twin Fins or Dual Fin Setups. Becoming popular in the late 1970s and early 1980s the twin fin became popular when Mark Richards used a twin-fin setup on his fish, winning four consecutive World Champion Ships getting himself in the Australian Hall of Fame.
Why do you need two fins on a surfboard?
Having two fins positioned near the rails of your surfboard will also add stability and hold in big-wave surfing when maintaining a high line is often critical. Lastly, quad fins are great for generating drive through turns.
How many fin boxes are there on a surfboard?
The options you have will be determined by the number of fin boxes in your board. It usually ranges from 1 to 5 fin boxes.
What is single fin surfing?
It is the most traditional surfboard fin configuration. Single fin setups tend to result in faster, direct down the line surfing.
What is a cant on a surfboard?
Fin Cant is the degree of outside angle a fin has in relation to the bottom of your surfboard. If a fin has zero cant, it is positioned at 90 degrees to the base of your board. This setup will be fast down the line, but it will lack responsiveness. If the cant of your fin is larger than 90 degrees, your board will be more responsive through turns.
What are the two most important elements of a surfboard?
The two most important elements of surfboard fins are the size and shape of the fins and how you setup your fins on a modern surfboard. However, there are a plethora of other variables to consider with surfboard fins as you’ll see below.
What is fin foil?
The fin foil is an aerodynamic shape when you look down the line of the fin. Much like the wings of a plane, this foil generates lift under the board. Different foil shapes result in different levels of performance in your surfing. There are a few of types of fin foils of which each have a few variations.
What is the difference between a bigger fin and a smaller fin?
The size of the fin will dictate your performance on a surfboard. A larger fin generally will provide more hold and also give you plenty of control in bigger surf. A smaller fin is going to be more loose and forgiving, but you’re going to sacrifice a lot of control and drive in bigger swell.
How does the fin of a surfboard affect the way a surfboard turns?
The length of the base of the fin (where the fin and bottom of board meet - typically the widest point of the fin) affects the way the board turns and drives out of turns. A larger base provides more surface area to push against the water when executing a turn, resulting in more hold during the turn and more drive out of a turn. This is a useful design for power surfers executing long/drawn out turns, but to turn sharper and quicker you may want to consider a fin with a slightly smaller fin base.
Why is a surfboard fin so flexible?
The flex of a surfboard fin, or lack thereof, is important for the affect it has on the feel of a surfboard. The flex that a surfboard fin has will directly relate to your projection into and out of turns, which in turn will produce speed and affect the control you have of the board. A stiff fin ultimately gives you the most control and stability while surfing - and therefore are great for when the waves get on the bigger side. Surfboard fins that are more flexible tend to offer a higher level of "board feel" and allow the surfer to push harder thru turns and get a bit more speed out of each transition. This however also leads to a feeling of less control over the surfboard.
What is a fin toe?
TOE. The surfboard “fins toe” refers to the angle of the fin compared to the stringer of the surfboard. While these change from board to board and shaper to shaper, they are typically toe-in, meaning that the front of the side fins are turned in towards the stringer, making the angle smaller. This causes the water to put pressure on the outside ...
What is a rake on a surfboard?
The rake measures how far back the tip of a fin curves in relation to its base, giving the fin its arc. The more rake that a fin has, the longer and more drawn out your turns will be - perfect for those big, lined up days where there is plenty of wall to work with. The less rake a fin has the tighter the fin will turn, therefore making it more maneuverable but sacrificing drive and stability. The fins are better suited for punchy, beach break conditions.
What is a glass on fin?
Glass-on fins are surfboard fins that are laminated into the surfboard when the surfboard is being built. These offer a smoother/more predictable feel when surfing, however are not removable. This can be an issue when traveling, as a broken glass-on fin can be a nightmare to repair.
What are the two major fin companies?
The two major fin companies are FCS and Futures. Most shortboards (and longboards for that matter) that you will see on the market today most likely feature one of systems.
What is a surfboard fin?
A fin that is straight up and down (90 degrees to the surfboard) has no cant. The less cant that a surfboard fin has the more drive and acceleration you will have, but lessens maneuverability. A fin with a good amount of cant will feel looser and more maneuverable.
How to change the feel of a fin?
The simplest way to change the feel of a single fin is to adjust the position of the fin on your board. Moving the fin forward in the fin box will make the board looser, which allows for easy turning. Moving the fin back towards the tail will widen the turn radius and give the board an overall stiffer feeling, which allows for more drawn out turns. Another way to change the feel of your board is to try a different size fin: larger fins will have more stability and control, while smaller fins will loosen things up. Additionally, experimenting with different amounts of flex can deliver fresh sensations; more flex delivers more power and projection in your turns, while less equates to a more responsive and quicker feel.
What is a quad in surfing?
Faster than thrusters, and with more drive than twin fins, quads align well with a “down the line” style of surfing that leans towards comparatively horizontal -- as opposed to vertical -- maneuvers. The notable increase in effortless speed is a consequence of reduced drag by way of eliminating the center fin, and the generous drive and hold come from 2 fins working with each rail. Quads also tend to be a favorite in racy barreling surf thanks to their unique combination of speed, drive, and hold.
What is a thruster setup?
The thruster setup has been the standard in high performance surfing for the past 25 years in great part due to its commendable ability to provide the ultimate blend of control and maneuverability in anything from small mushy waves to 15 foot barrels. This blend of control and maneuverability provides access to the upper echelons of modern performance surfing, but also allows for classic surfing with clean, powerful lines. Typically, a thruster setup will have 3 fins of the same size and template, but there exists room for tinkering -- e.g. some thrusters have a slightly smaller center fin for a looser feel.
