The Fin
This fin was designed by the Campbell brothers to specifically pair with their Bonzer surfboards in order to complement the unique bottom contours and fin setups of their 3 and 5 fin designs.
The Bonzer concept dates back to 1970 when brothers Malcolm and Duncan Campbell took action on their desire to ride shortboards in good sized surf, without the limitations that came along with the single fin and twin fin designs of the day. With a little inspiration from their dad, the Campbell brothers created the first standardized tri-fin surfboard… The Bonzer 3. Later, in 1982 the 5 fin Bonzer was born, presenting another massive shift in design and performance potential.
True Ames’ roots are deeply entangled with the Campbell brothers, who were some of its original clients back when the shop was just getting started - and the two are still working alongside each other to this day! While much has undoubtedly evolved since then, the Campbell brothers’ fin and bottom design systems live on through the decades and continually compete toe-to-toe with modern day surfboard concepts.
The Bonzer center fin works synergistically with the additional runners to efficiently organize water flow across the bottom of the surfboard, resulting in a highly optimal transfer of energy. If you have a Bonzer board, then this fin is the official prescription prescribed by the Campbell brothers to fix it up for maximum performance.

From True Ames
The Campbells shaped this fin around the runners, not against them: the center fin and the canted runners share the load, so the board drives like a single fin with far more push behind it.
Our take
On a Bonzer-bottom board this is the engine of the system: planted, line-holding glide with far more push than a plain single fin, rewarding riders who set a line and run it. But it only makes sense paired with Bonzer runners on a Bonzer bottom — if your board is not a Bonzer, this fin has nothing to organize and a standard single or tri will serve you better.
More About This Fin
The True Ames Bonzer center fin was designed by Malcolm and Duncan Campbell and is made in solid fiberglass. It comes in four sizes — 6.0", 6.5", 6.75", and 7.0" — all with a full base and mellow rake. It is built to run as the center fin of a Bonzer setup alongside Bonzer runners on a Bonzer-bottom board. Sizing scales with the board: 6.0" for shorter Bonzers, up toward 7.0" as length and volume climb.
