This is a brand new, unused Starfin, which is now difficult to obtain. Furthermore, it's a treasure with a handwritten signature by Shane Horan!! FIN: CENTER BOX FIN Material: Polycarbonate Length: 8ft (Height 19.5cm x Width 17.5cm) Color: PURPLE MADE IN AUSTRALIA STARFIN In the early 80s, Shane Horan, an Australian hero and former CT surfer, researched the speed and movement of yachts and repeatedly tested using advanced fluid dynamics methods to develop and commercialize this Y-shaped tip single box fin. It became a worldwide topic for faster take-offs, lighter turns, and increased speed. Pro Takao Kuga, who has won the JPSA Grand Championship five times, also achieved amazing performance and results with this Starfin for a time, becoming a hot topic in Japan. Suitable for single fin boxes on shortboards, mid-lengths, and longboards. There are some irregularities in the product, but this is due to the addition of stiffness to improve the fin's flex. This does not affect the quality of the product, so please understand. STARFIN Starfin Surfing Single fin Longboard Jeff McCoy MacCoy Shane Horan Takao Kuga McCoy
