Dan Mann's high performance groveler.Think small wave grovel, fast and fun. No-paddle takeoffs, buttery floaters. The Sweet Potato is probably the widest, flattest, thickest small wave surfboard you will ever surf. It's high performance but it's definitely a groveler, this shape is the absolute most fun you can have in really bad waves. It's the board that should never leave your trunk.This is the updated Sweet Potato, refined with a swallowtail - the latest iteration of Mannkine's small wave shape that transformed what surfing is for many. It converts waves that would normally require a longboard (if even) into rippable potential and fun because of the generous volume packed into a small package that is loose and generates tons of drive. The trademark deep double barrel concave essentially splits the board in half when tipped over and driving through turns, making the board feel way more narrow than it actually is. The new tail outline, combined with some tweaks on the bottom contours through the fins, has increased the maneuverability for tighter pocket turns without taking away the projection and grovel speed in gutless surf. *** Helium Core Technology A stringerless EPS core with flex controlled at the rails made from Paulownia and Balsa wood - this construction is light and lively underfoot, and excellent at generating speed in everyday waves. Volcanic Lamination Technology Forged in fire, this Basalt lamination technology is our sustainable alternative to carbon, and is our most durable with elevated response.
