Abstract
Watersport board fins with fin retention systems and associated watersport boards and methods. A fin includes a hydrodynamic blade and a fin base extending from the hydrodynamic blade. The hydrodynamic blade defines a fin plane and includes a leading edge, a trailing edge, and a foil surface. The fin further includes a fin retention system with a selective retention system that includes a retainer and an actuator coupled to the retainer via a pivot shaft. The actuator forms a portion of the hydrodynamic blade when the selective retention system is in a locked configuration and is configured to rotate away from the fin plane when the selective retention system transitions from the locked configuration to an unlocked configuration. The retainer is configured to rotate away from the fin plane when the selective retention system transitions from the unlocked configuration to the locked configuration.
