The Atlas Paddleboard Fin was optimized for tracking, speed and efficiency. It requires no tools, so leave the screwdrivers and hex keys at home where they belong. It's large size allows for superior tracking, while it's hydrodynamic shape provides speed and efficiency. The Atlas Fin was designed as a replacement fin for the 2022 Tarpon 10'6”, Tarpon 11'6” and Dorado 10'6” Paddleboards.
