Fins Unlimited Joel Tudor Fin

This fin is designed for traditional longboarding, specifically for surfers who enjoy pivot turns, nose riding, and maintaining a classic, smooth style. Its geometry encourages tighter turns from the tail while providing the stability needed for extended time on the nose.

This fin is compatible with any standard US Box system, which is the most common fin box found on longboards. If your board has a single slot with a sliding plate and screw mechanism, this fin will fit.

A 10-inch depth provides significant hold and stability, which is ideal for larger longboards or surfers who want a locked-in feel. It offers more surface area to pivot against, making it easier to initiate turns from the center of the board compared to smaller, more raked fins.

It leans heavily toward traditional logging. While it has updated geometry for a more modern feel, it is fundamentally a pivot-style fin intended for classic, flowing lines rather than high-performance, aggressive maneuvers.

You will need a standard fin screw and plate, which are typically included with your surfboard's fin box. You will also need a flathead screwdriver or a specialized fin key to tighten the screw once the fin is positioned in the box.
