[ Twin Fin ]
Twin Fin is designed for knee high to well overhead waves in
all conditions. Twin fins first appeared in the late '60s, but were
somewhat overlooked until Mark Richards embraced the design in the
mid '70s and early '80s. The narrow tails common to single fins could
limit performance with their lack of surface area. The extra surface
area in the tail of twin fins provide lift, acceleration and speed.
The surface area combined with the two fin configuration yields a
fast, loose, and responsive surfboard. Design features -
Rocker: Low Speed Box, Low Continuous, or Low Relaxed.
Profile: Moderate foil with adequate volume. Outline:
Moderate cut swallow for a classic twin or any of the contemporary
shortboard tail configurations. Bottom Contours: Vee or tri
plane entry to tri plane wide point to panel vee wide point to tail.
Or vee entry to single concave wide point to shallow double concave
spiral vee from wide point to tail. Rails: Moderately full
rail with foiled rail profile for control for bigger surfers. Lower
moderately thinner rail for smaller surfers.
