True Ames Bonzer

Yes, this is a standard single-fin base design, so it fits into any standard longboard-style fin box. However, it is specifically engineered to work in conjunction with the side runners found on Bonzer-style surfboard setups.

The size selection generally depends on the length of your board and your personal preference for pivot versus drive. A smaller 6.5-inch fin will feel looser and more responsive in tight turns, while the 7-inch option provides more stability and hold through drawn-out carves.

The Campbell Brothers design is specifically shaped to manage water flow through the concave bottom contours of a Bonzer surfboard. It works in tandem with the side runners to create a more efficient energy transfer, resulting in better speed generation and tighter, more precise turns.

While you can technically put it in any board with a standard fin box, it is optimized for the specific hydrodynamics of a Bonzer setup. Using it on a standard single-fin board may result in a ride that feels quite different from what you are used to, as the template is designed to work with side runners rather than alone.

Yes, the material impacts the flex pattern of the fin. Fiberglass provides a stiffer, more traditional feel with consistent drive, while the honeycomb construction is lighter and offers a bit more flex, which can make the board feel slightly more lively and responsive.
