How to Choose a Longboard Fin

The first type of fin used on surfboards was a metal boat keel, according to Matt Warshaw's Encyclopedia of surfing. The fin didn't truly catch on in surfing until 1940, and up until 1970, only a single fin was used. Today surfers can choose anything from a single fin to five fins. The fins may be permanently attached through glassing or removable, allowing you to swap out fins. Long board surfers typically adopt either a single fin or a tri-fin configuration, depending on their needs.

      Check whether your fins are removable. Take your board to a surf shop to remove glassed-in fins and replace them with new fins. Removable fins are easy to replace on your own.

      Select fins based on your surfing abilities. Longer, single fins provide greater stability, making it easier for you to get up and to balance on the board. Tri-fins make your surfboard faster and more maneuverable.

      Talk to someone at your local surf shop about the strengths and weaknesses of a single fin versus a tri-fin configuration. Employees at a surf shop usually know the local conditions and are in a position to advise you on the most appropriate fin, or fins, for those conditions.

      Experiment with different fins. Ask some of your fellow surfers if you can borrow their boards to try out the fins. Talk to them about whether they like their fin, or fins, and ask them to explain why.
