True Ames has been making high quality surfboard fins since 1979 and is a huge presence in the alternative surfboard world today. The Greenough 4-A has been the most popular single fin design for nearly 40 years. The full base combined with a tapered, moderately flexible tip provides solid drive off the bottom and sharp responsiveness through arcing turns. Designed for both generating speed and surfing in the pocket, the 4-A is a fin that holds when you need it and releases when you need it.
It has slight signs of use, but can still be used as is.
