Twin Surf Fins

A twin setup is usually found on retro boards. This fin setup makes your board very loose and manoeuvrable. Twin fins have two large fins at the side of the bottom of a board, which are foiled. This gives your board sidewards pressure and more grip on the rails. This is why boards with a short rail line, or very round boards with little effective rail, usually have a twin fin setup. This setup gives the board more grip. Besides this, the absence of a fin in the middle, enables the water to flow through easily. This allows for more speed, decreases the amount of control though. For example, check out the twin fins of Future fins, FCS and Feather!
