The Oxnard plain is one of most fertile places on Earth, but historically, despite an extremely hollow harvest season, the surfers taste a bit sour. Still, sometime in the1970s the offshore winds blew the pesticides and pot smoke in a direction just right for innovation, and the Campbell brothers created the Bonzer fin setup: a stubby little center fin accompanied by two or four runners. Ignore all imitations.
This fin was designed by the Campbell Brothers with the intention and specific purpose of being paired with their Bonzer Surfboards. This center fin is meant to complement the unique bottom contours and fin setups of their 3 and 5 fin designs.
The Bonzer fin works synergistically with the additional runners to efficiently and effectively organize water flow across the bottom of the surfboard, resulting in a highly optimal transfer of energy. If you have a Bonzer board, this fin is the official prescription prescribed by the Brothers Campbell to fix it up for maximum performance.
