Captain Fin Co. Jeff Mccallum Glass

The fin is constructed from a specialized glow glass material that absorbs ambient light during the day. Once the sun goes down, it emits a visible glow, making it a functional and aesthetic choice for sunset or twilight surf sessions.

This fin is designed for surfers who prioritize maneuverability and responsiveness. Its narrow base and flexible template make it ideal for tighter turns and more active, lively longboarding rather than traditional nose-riding or heavy trim.

Yes, this is a standard single fin designed to fit into any universal longboard fin box. It uses a standard fin screw and plate system for installation.

The flexible template allows the fin to load up and release energy through turns, which helps the board feel more lively and responsive. It is particularly effective for surfers who want to pivot quickly rather than relying on the stiff, drive-heavy feel of a traditional fiberglass fin.

A 9-inch fin is a versatile mid-range size that works well on most standard longboards between 9'0" and 9'6". If you are riding a larger board or prefer more hold, you might consider a larger fin, but for most, this size offers a balanced feel.
