Traditional longboard control with durable solid Pro Glass construction and International 4A template balance.

The 10" International 4A Center Fin is a traditional single-fin template developed for controlled trim, smooth turning response, and dependable hold in longboard surfboards. Manufactured from solid da-blue Pro Glass fibreglass, the fin provides consistent flex characteristics and structural durability suited to everyday surf use.

The International 4A-style outline combines a balanced base, moderate rake, and refined tip profile to support predictable rail-to-rail transitions while maintaining stability during noseriding and drawn-out turns. Its 10-inch depth is suited to full-length longboards requiring reliable tracking and smooth directional control.
