• 1. Enhance stability: The fins can be inserted into the water to form support, reducing the left and right shaking of the surfboard, especially when beginners stand or deal with turbulence, to avoid imbalance caused by unstable board body.
• 2. Improve handling: By adjusting the angle and force of the fins, the steering and wave cutting of the board can be precisely controlled. For example, when making steering movements, the fins can quickly transmit force, making the movements more flexible.
• 3. Enhance propulsion: When the water flows through the fins, a reactive force is generated to assist the plate in sliding on the waves, reducing speed loss, especially in small or gentle wave areas, which can extend the sliding distance.
• 4. Optimize balance: Multi fin systems (such as three fin and five fin) can evenly distribute water resistance, allowing the board to maintain balance in different wave conditions and adapt to surfers of different weights and sliding styles.
• 5. Adapt to various wave conditions: Fins of different sizes and shapes can cope with different wave types, such as large fins suitable for large waves to enhance grip, and small fins suitable for small waves to improve flexibility and surfing adaptability.
