SIMILAR TO THE robinson, the zappa is a bonzer inspired shape with a slightly straightened outline built for speed. invented by the campbell brothers, the bonzer is time tested and the zappa is a modernized version of the classic for todays surfing. made for deep barrels and built to surf circles around snakes and kooks alike. a slight concave to a “vee” with a deep double centered concave coming out the tail. 3 or 5 fin setup with a center box design to utilize an approximate 7” inch center fin, making the zappa unique edition to our lineup.
