The Phase Five 1-inch Skim Fin is the standard fin offered on many Phase 5 boards. This wakesurf fin is a great fin choice if you are looking for a loose ride that still will have some stability. If you are currently running either one or multiple 2-inch fins this is a great choice if you are looking to have a fin that will break free easier on spins or shuv maneuvers *Includes ribs and 1.25" screws (1” screws fit the Shrimp and Scamp) https://www.phase5boards.com/blogs/phase-5-wakesurfers-blog/phase-5-finology
