Twin Fin Meaning in Surfing

The twin fin is a surfboard setup that uses two side fins. This arrangement lacks a center fin which results in a very fast feel. The board moves quickly because there is less drag under the tail area. Twin fins are known for being loose and easy to pivot in surf. This setup works best in small to medium waves with flat sections. Surfers enjoy the skatey and free sensation of this two fin design. A surfer zips across a small wave on a wide twin fin. Maintaining rail pressure is vital to keep the board from sliding out. One rider performs a wide carving turn on a classic twin fin. This fun and fast configuration offers a unique alternative to standard three fins.
