The nanazero's Classic center fin complements the nanazero MID02 perfectly, featuring a wide base width (root part) that provides straightness and stability, resulting in relaxed and pleasant turns in large arcs. It's an excellent choice for surfboards that prioritize stability or cruising, even beyond the nanazero brand.

Term related to Fin

We will explain the terminology and principles behind the elements that define the characteristics of fins:

fin

Base

The length of the horizontal part where the fin meets the surfboard.

A longer base enhances drive power and facilitates speed gain. Conversely, a shorter base improves turning performance and makes turning easier.

Depth

The length (height) of the vertical part of the fins protruding from the surfboard into the water.

Greater depth increases stability but also increases turn resistance. Conversely, smaller depth results in smoother turns but sacrifices stability.

Area

The area where the fin extends outside the fin box.

A larger area enhances stability and drive power but increases resistance. Conversely, a smaller area facilitates easier turns.

For longer boards and heavier riders (and boards), a larger area is required.

Sweep

The angle of inclination of the fin.

A greater sweep angle increases stability and drive power but also increases turn resistance. Conversely, a smaller sweep angle improves turning performance, results in smoother turns, and reduces turning radius.

Foil

Bulges on both sides of the fins.

Foil controls water flow. The "50/50" configuration, with bulges on both sides, is commonly used for center fins. The "Flat" configuration, flat on the inner surface and bulging on the outer surface, is commonly used for side fins.

Cant 

The angle at which the fin is tilted from a vertical angle of 90 degrees to the bottom surface of the surfboard.

Center fins are usually at 0 degrees (perpendicular to the board), while side fins are angled a few degrees. This angle increases water resistance when the board is tilted, enabling sharp turns.

Notes
  • Some foreign substances, such as black dots, may be present due to the nature of the manufacturing process. Thank you for your understanding.
  • Scrape marks resembling grazes may be visible on the base due to the manufacturing process, but they are not considered defects.
  • While nanazero's fins are inspected to conform to the fin manufacturer's standard size before shipping, in rare cases, they may be difficult to fit due to compatibility issues with the fin box, or the fins may wiggle if the box is too large.
  • If the fins do not fit, do not force them, as they may become stuck. Instead, adjust by gently scraping the bottom of the fin with sandpaper.
  • If the fin wiggles and does not sit securely due to the fin box being too large, adjust the base thickness by applying aluminum tape for stability.
  • Fins made of hard materials can cause injury upon contact. Please exercise caution to avoid contact with people during wipeouts. If the fin tip is sharp, rounding it with sandpaper can help prevent injuries.

    Tight and Doesn't Fit As Is きつくてそのままではハマらない

    As fins, they are neither particularly good nor bad. I was happy that they came in a case. However, needing to sand them down significantly to fit into the box is a bit of a problem. I'm not sure if the issue is with the fins or the box.

    フィンとしては可もなく不可もなくといった感じ。ケースに入っていたのは嬉しかったです。ただヤスリでかなり削らないとボックスに入らないのはいかがなものでしょう。フィンに問題があるのかボックスに問題があるのかはわかりませんが。
