Captain Fin Jeff McCallum Quad

These fins are specifically designed for retro fishes, hybrid shapes, and boards with wider tails like squash or swallow tails. The raked template helps stabilize wider tail blocks, making them a great choice if your board feels a bit loose or skittish in turns.

The solid fiberglass construction provides a very stiff flex pattern, which translates to maximum drive and speed. You will notice less flex during turns compared to composite or plastic fins, giving you a more direct, responsive feel when pushing hard through maneuvers.

Yes, these fins are designed for the FCS II system. While they are compatible with the tool-less FCS II boxes, they also come with screws if you prefer to secure them for extra peace of mind.

The flat inside foil is designed to provide a consistent, predictable feel. It offers a clean water flow that creates a balance between speed and control, making it easier to hold your line on open wave faces without the fin feeling too twitchy.

While they are high-quality, these fins are generally better suited for intermediate to advanced surfers who have a developed sense of how fin flex and template shape affect board performance. If you are still learning the basics, you might find the stiff, performance-oriented nature of these fins less forgiving than a more flexible, neutral template-base fin.
