The simple answer is: Yes, you can surf without fins. Honestly you can surf anyway and whatever you want. Whether it works or not is a whole other question. But finless surfing is possible and it works.
Fins are important because they give 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 board without fins. There are many different fin setups.
The size of the fin affects your performance. A larger fin generally has more support and also offers a lot of control in bigger surf. A smaller fin, on the other hand, is more forgiving and looser, but you will sacrifice a lot of drive and control in bigger surf.
Fins can provide lateral lift against the water and stabilize the board’s trajectory, allowing the surfer to control direction by varying their lateral weight distribution. The introduction of fins in the 1930s revolutionized surfing and board design.
Single fins are best for surfing small/medium, fat and weak waves. Since one fin creates less drag than multiple fins, they are most useful when surfing smooth, slow turns. That being said, if you’re trying to make quick turns or moves, a single fin won’t handle it as well as a multi-fin setup.
From beginner to expert, the Tri-Fins will always be the answer. The additional +1 fin on the back provides more stability and maneuverability. And since it has 3 fin boxes, you can ride with a single fin or twin fin style.
Today 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, are angled towards the middle (“toed-in”) and can be flat on the inside to increase water handling and speed.
Our fins look like modern airplane wings and boat keels
Surfing (and SUP) is all about speed and control, catching lots of waves and long surfing or paddling sessions before you tire out. We designed our fins to help people catch more waves, maneuver better and have longer surf sessions.
Fins have gotten ridiculously expensive in recent years, and for one very simple reason. People are willing to pay that much. Fins rock the Keystone markup and serve as great up-sell items. Ever worked in a surf shop?

Most surfboards in your local shop do not include a set of fins with the price of the board. Surf shops love this because now you have to hover over the fin wall and pick a set that will cost you at least $40.
Rake – also known as sweep – is the distance the fin tip curves away from the base. The rake affects the ability of the board to turn. The smaller the rake (i.e. the more the tip deviates from the base), the less maneuverable the board is and the longer and more tedious the turns become.
Fins typically act as foils that generate lift or thrust or provide the ability to control or stabilize motion while propelled in water, air or other liquid. Ribs are also used to increase surface area for heat transfer purposes or simply as an ornament.
Tri-fin/Thruster: The pro. The World Championship Tour is largely the home of the thruster. Fast, responsive and mature with a variety of choices, the Thruster is the top choice for most when it comes to performance. Three fins allow a surfer to pump water out the stern to generate propulsion.
You need a fin on a paddleboard to maneuver it properly. Without a fin you would be spinning in a tight circle. The paddleboard fin also adds stability to the board.
A single fin feels slack and has more speed across the board. They’re faster to turn, but not as sharp and with less drive than a 2+1 setup.
Surfing is not a complicated sport. Unlike many other water sports, the truth is that surfing only requires a surfboard and someone willing to ride the ocean waves. The basic surfing equipment for beginners consists of a surfboard, fins, a leash, wax and a wetsuit.
Blake Peters: Twin fins have great speed and flow and it’s a different surfing style in general; a little more graceful and less aggressive. Twins are great when you’re surfing somewhere that has a point break or wave that lets you run and open face.
