This revolution, “The Bonzer Experience”, is about evolution: evolving ones thoughts, experiences and consciousness. It’s about dynamic changes that produce quantum shifts in understanding and performance.

J.G. Bennett, describing Gurdjieff’s concept of evolution, states, “Evolution is the production of high level energy from a lower level source.This requires an apparatus of a different kind; for the “upgrading” of energy is improbable and cannot occur at all unless some high level energy is present. Life is an evolutionary process that goes against the direction of probability. The work by which Mankind is transformed is evolutionary.”

This quote sums up in a nutshell, more than 30 years of some pretty intense work. In 1970 the 3 fin Bonzer represented a quantum leap in possibilities, and in late 1982 the 5 fin Bonzer presented another tremendous shift in design and performance potential. Maybe it was pure naiveté or a misguided sense of mission, but whatever it was, ever since the first wave we rode on a Bonzer we have felt an obligation to continue refining the design in order to keep possibilities open. We have wanted to give something back to surfing, which has so greatly enriched our lives.

Against all probability the Bonzer stands here today as a symbol of the open-ended nature of evolutionary potential and performance capabilities.

How the Bonzer System works ?

mecanisme-bonzer-surfboard-compressorThe primary purpose of the Bonzer system is to efficiently organize water flow. We have done this 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. When you’re doing a turn, the water travels diagonally across the bottom of your board. The Bonzer side fins have a base totaling 9-3/4” on each side, and a maximum depth of only 2-3/4”. The angle, combined with the shallow depth of the fins, allows the fins to come in and out of the water with little resistance. This makes rail-to-rail transition much easier, which in turn allows you to keep your board on the rail with much less effort.

While turning, the fins on the inside rail are fairly vertical in the water, providing very refined edge control. As the water races across the bottom, the outside fins deflect it down and back through the tail. We have always looked at the water that escapes off the outside rail as unused energy. The combination of the Bonzer concaves and the long base of the side fins redirect far more water through the tail area than other designs. This maximizes the use of the force that is created during turns. The fins are essentially an extension of the concaves and, since water adheres to curved surfaces, there is very little disturbance as the water passes through the fin area. This dramatically reduces drag. Basically, we have tried to create surfboards that you can get more out of with less effort and energy input. It’s all about reducing entropy.

BONZER 3 Fin Versus BONZER 5 Fin


The Bonzer 3 and 5 fin systems have very similar performance characteristics.

The main difference is that the 5 fin setup is a bit quicker off the top, and is more maneuverable in the hook. This makes it more conducive to a contemporary approach to wave riding. The 3 or 5 fin systems can be used on any model. This will produce a slightly different feel in each, but inevitably, the shape of the board will determine more the way the board rides than the fin set up. For instance; putting the 5 fin setup on a Russ Short Model is not going to turn it into a contemporary shortboard.

The position of the center fin can vary from surfer to surfer. We have included a basic guide within the description of each particular model. This is not etched in stone. Please feel free to experiment. A few general rules are:

If you are having trouble finishing out turns and cutbacks, or are not getting up and down the face quickly enough, you should move your fin up approximately 1/8” to 1/4”.
If you are digging rails, or catching rails in the front 18” to 24” during cutbacks, you should move your fin back approximately 1/8” to 1/4”.
The leading edge of the the center fin usually ends up about even with the trailing edge (at the base) of the of side fins, plus or minus 1/4”.
Please understand that these are basic guidelines, and are relative to where you stand on your board, and if you are standing in the right spot according to your style and the type of board you are riding..
