1. single fin

A single fin is basically a long board, but it can also be a beginner’s board. The single fin provides stability and control, a smooth and natural feel that no other tail fin system can provide, and is suitable for all wave conditions.

Unfortunately, more control means less performance, because a single fin limits surfing to lean turns and straight line changes.

2. twin fin

Split the middle fin on either side of the tail of the board, The goal is to get the water flowing in the middle to increase speed and improve turning, the disadvantage is that the stability is relatively low, not suitable for large waves, but it is more maneuverable in small waves and is suitable for use with a sensitive fish board because it can increase speed.

3. thuster

Typical of modern surfboards, which combine single fin and twin fins for sensitivity and stability,

this thrust type of rudder is the most common, these devices can be found on all surfboards. In most wave conditions, they perform well, you can feel stability when you use a maneuverable surfboard. the inner side of the left and right fins is flat to increase momentum, middle fin is normal shape fin. in addition, the outer fins are tilted inward toward the tip of the plate, making it easier to turn around.

Thuster have two combinations, one is three small caudal fins, another one is 2+1 caudal fin, that is, one large caudal fin and two small caudal fins.

At the same time, the stability of the three fins(Thuster)increases the speed and agility, which can be mounted on a variety of surfboard types. If you need a little more flexibility than a 3-fin, consider using a 4-fin, suitable for both modern short boards and vintage fish boards, but this kind of caudal fin is still relatively rare in China.
