FEATURES
1. Collapsible Design:
- Ensure the fin is designed to collapse or fold easily for convenient storage. This could be achieved through a hinge or flexible materials that allow the fin to bend without losing structural integrity.
2. User-Friendly Adjustment:
- Make the adjustment process user-friendly. Whether it's changing the length, angle, or folding the fin, the process should be intuitive and not require special tools.
3. Durable Materials:
- Use durable and resilient materials for the fin that can withstand the stresses of surfing and the repeated bending for storage. Consider materials such as reinforced plastics, carbon fiber, or other composites.
