## Overview

Compatible with a wide range of SUPs and longboards, it includes a no-tool fin screw and plate for easy installation.

## Description

The Santa Barbara Surfing 8" Center Fin is designed for surfboards and stand-up paddleboards that use a standard US center fin box. Its classic single-fin format works well as a replacement or spare center fin for compatible longboards and SUPs. FITMENT: Compatibility depends on the fin-box system, not simply the board brand or model. This fin uses the traditional screw-and-plate mounting system found in standard US center fin boxes, including many common 8.5" and 10.5" boxes. It is not intended for proprietary slide-in, snap-in, or other non-standard fin systems. Before ordering, compare your existing fin and fin box. Make sure your board uses a standard center box and has adequate space for an 8" fin. Board designs and fin systems can vary even within the same manufacturer. The fin is made from glass-filled nylon and includes a no-tool fin screw and fin-box plate. The hand-tightened screw makes installation, removal, and fin-position adjustments convenient without a screwdriver. Suitable for compatible longboards, surfboards, and stand-up paddleboards for surfing, paddling, cruising, and general replacement use.

## Features

- FITS STANDARD US CENTER FIN BOXES: Designed for longboards and paddleboards with a standard US center fin box, including common 8.5" and 10.5" center boxes. Check your existing fin box before ordering.
- CHECK YOUR FIN SYSTEM: This is a screw-and-plate style center fin. It is not designed for proprietary slide-in, snap-in, or other non-standard fin systems. Board brand alone does not determine compatibility.
- 8" GLASS-FILLED NYLON FIN: Classic 8-inch center fin made from glass-filled nylon for surfing, paddling, and general replacement use on compatible longboards and SUPs.
- NO-TOOL FIN SCREW INCLUDED: Includes an SBS no-tool fin screw and fin-box plate so the fin can be installed, removed, or repositioned by hand without carrying a screwdriver.
- REPLACEMENT CENTER FIN: A practical replacement or spare for compatible surfboards and stand-up paddleboards. Compare your existing fin, mounting system, and available fin-box space before ordering to help ensure proper fit.
