Rail fins enable high-performance surfing, and are most often " single-foiled ," with one flat side and one " foiled " side, as seen on an airfoil, for greater lift.

Rail fins are more or less engaged by the rider's heel and toes as they lean in the desired direction of their turn.

Rail fins also add lift ( known as " drive ") in trim and with greater holding ability, enable steeper wave faces to be ridden and higher speed " down the line.

Rail fins are typically " toed-in ," that is, the leading edge of the fins are oriented toward the centerline of the surfboard, which decreases the angle of attack in trim, which makes it easier to initiate turns.

Rail fins also typically have some degree of " cant ," that is, are tilted out toward the rail they are adjacent to.

Rail fins evolved into being and surged into popularity as riders ( Simon Anderson, most famously ) sought a solution to two major performance issues of a central " single " fin-both related to engagement of the foil: For one, a centrally-mounted fin is tilted up out of the water as the board is leaned over, and thus it loses more and more of its lift as the lean angle increases-if the lean angle is acute enough, the fin's tip can be the only area left in the water ; the tip may then rapidly stall and, having lost its lift, become disengaged from the water, leaving the board's bottom as the only control surface still operating.
