Frequently Asked Questions

Q: What board types is this quick-release surfboard tail fin compatible with?

A: This detachable tail fin is designed to be compatible with a wide range of watercraft, including surfboards, longboards, stand-up paddleboards (SUPs), and kayaks. As long as your board has a standard fin box slot that matches the fin base dimensions (245mm × 115mm), the fin should fit securely.

Q: What sizes are available, and how do I choose the right one?

A: The fin is available in five sizes: 4.5-inch, 8-inch, 9-inch, 9.5-inch, and 10-inch. Larger fins generally provide more directional stability and tracking, making them ideal for longer boards and flatwater paddling. Smaller fins offer more manoeuvrability, which suits shorter boards and wave riding. Refer to the size chart in the product images for exact measurements.

A: No tools are required. The fin features a quick-release plug-in design that lets you attach or detach it by hand within seconds. This makes it extremely convenient for travel, storage, and switching between boards.

Q: How durable is this fin for regular saltwater use?

A: The fin is constructed from high-quality nylon, which offers excellent resistance to the corrosive effects of saltwater and UV exposure. It is built to handle the regular demands of surfing and kayaking, making it a reliable long-term addition to your gear.
