Captain Fin Co. Jeff McCallum Fin

This fin is designed primarily for mid-length surfboards. Its template excels in boards that require a balance of hold and maneuverability, particularly when you want to draw out long, fluid turns on open faces.

The stiff fiberglass construction provides a predictable, stable feel underfoot. Unlike more flexible fins that might whip or spring out of turns, this fin offers a solid, reliable response that helps you maintain speed and control through carving maneuvers.

The narrow base is intentional; it allows for easier pivoting and tighter turns compared to a wide-based fin. While it offers less 'drive' off the bottom than a wider template, it compensates with increased maneuverability and a smoother, more fluid sensation when transitioning between turns.

This fin is better suited for style-focused surfing rather than high-performance, vertical snaps. It is engineered for sweeping arcs and maintaining flow, making it ideal for cruising, trimming, and carving on mid-length boards rather than aggressive, top-to-bottom surfing.

An 8-inch depth is a versatile size for most mid-lengths, offering enough surface area to hold the board in the water during turns without feeling overly draggy. It provides a good middle ground between a smaller, looser fin and a larger, more locked-in single fin.
