The Square Tail
The square tail, also known as chop tail, is the father of all designs. It's a high-volume tail shape that will plane fast across the water while offering a lot of stability. It's a great shape for mushy waves or slow sections of a wave. The square tail will react fast in short, tight turns. It is rarely used in modern surfing.
The Squash Tail
The squash tail, also known as rounded square tail, is the most common surfboard tail shape in the world. It delivers a comfortable and balanced feel regarding stability and maneuverability because it combines the benefits of the square and round tails. The squash tail is a versatile shape that will give you both control and hold in all kinds of waves, but especially in small to overhead surf.
The Pin Tail
The pin tail is the shape of choice for those seeking to get barreled in dramatic conditions. This tail design holds tight in the face of the wave and minimizes lift. It features the narrowest width of all tail shapes, which results in a directional surf, and maximum water flow. It can be hard to turn, and will not perform well in small waves. The round tail is the ideal tail shape for big wave surfing guns.
The Round Tail
The round tail offers a loose feel in terms of maneuverability and will provide enough hold in hollow and steep wave conditions. It is more versatile than the pin tail, and the extra surface area will deliver more speed in slow sections of the wave.
The Swallow Tail
The swallow tail is a popular design for both small and high-performance shortboards because it offers stability, control and hold when transitioning from rail to rail.
The Asymmetrical Tail
The asymmetrical tail is a 21st-century design created for backside and frontside wave riding. It usually combines two different shapes for the left and right sides of the tail, and offers traction and hold.
The Rounded Square Tail
The rounded square tail adds hold and less responsiveness to the original square tail.
The Rounded Pin Tail
The rounded pin tail is a blend of the pin and round tails. It offers stability and good speed.
The Bat Tail
The bat tail resembles the swallow tail, but it offers and central point of contact with the water.
The Wing Tail
The wing tail is a combination of rail shapes and the swallow tail.
The Thumb Tail
The thumb tail is a compromise between the squash and the round tails.
The Fish Tail
The fish tail is a wider version of the swallow tail that will excel in small wave conditions. It was a popular tail during the twin fin years.
The Diamond Tail
The diamond tail offers a sharper and more pivotal experience when turning, compare to the rounded pin tail.
