Dolphin fin refers to a swept-back single-fin template with a curved, flowing outline designed to balance hold, stability and smooth, high-arc turning. With a moderate base, extended rake and tapered tip, dolphin fins promote fluid turning, trim control and predictable rail engagement across a wide range of longboard and mid-length conditions.
Their behaviour depends on tuned fin foils, moderate fin cant, balanced toe-in and precise fin placement, which define how the fin drives through longer turns and maintains centred trim.
Dolphin fins are commonly paired with single-fin longboards, performance logs and 2+1 setups, enhancing flowing lines, projection and stability while maintaining a classic, balanced feel.
Shapers refine dolphin fin performance through template tuning, foil balance and material or construction choices that maintain responsiveness, feedback and control.
