Captain Fin x Alex Knost BMT Bonzer Surfboard Fin

This fin is specifically designed for eggs, mid-lengths, and specialized bonzer setups. Its upright profile and 50/50 foil are tailored to complement the specific rocker and rail lines of these boards, providing a balance of drive and pivot.

Volan fiberglass is known for its distinct flex pattern. It provides a lively, responsive feel through turns, allowing the fin to load up and release energy more effectively than stiffer, molded plastic alternatives.

Yes, it is designed to be compatible with all standard single fin boxes. You won't need any special hardware or adapters to install it.

A 50/50 foil is symmetrical, meaning both sides of the fin are curved identically. This design provides consistent, predictable water flow, which helps stabilize the board and keeps it tracking straight while still allowing for smooth rail-to-rail transitions.

While it is a high-performance template, it is quite versatile. If you are riding a mid-length or an egg, this fin is a great choice for learning how to engage your rails properly, though it is primarily aimed at surfers looking to refine their setup for specific board types.
