Curiosity takes you places, right? One of the most interesting designs on surfboard mechanics, the Bonzer, was born thanks to the curiosity of the Campbell Brothers. The primary purpose of the Bonzer system is to efficiently organise water flow. By designing fin and bottom systems that work in a synergetic fashion in order to maximize the use of the energy that is created by the water passing through the tail area of the board. This fin has being designed to work on any kind of Bonzer surfboards. Thanks for being curious :)"
