Surfboard Fin Size Guide
The Eveley 7" International 4A Center Fin is built around one of the most trusted templates ever used in surfboard design.
The balanced outline combines a stable base, moderate rake and clean tip release, creating a center fin that holds its line when trimming yet still redirects smoothly through turns.
In a 2+1 setup, the 7" size works as the stabilising engine of the board — giving you the hold and drive you need while allowing the side bites to keep the board lively.
Constructed from solid Pro Glass fiberglass, this fin provides the planted feel surfers expect when pushing through longer arcs or maintaining trim across fast sections.
The blue-on-white finish adds a crisp, classic look that stands out without overpowering the board.
If you want a center fin that simply works in almost any mid-length or 2+1 configuration, the 7" 4A is one of the most reliable choices available.

Many center fins either lean too far toward tight pivot or drawn-out rake.
The International 4A template sits directly in the middle.
That balance makes it one of the most versatile center fins ever produced.
You get:
• dependable hold when trimming
• smooth flowing arcs through turns
• predictable response in almost any board
This is why the 4A template has remained one of the most widely used center fin designs in surf history.

FAQs
What boards work best with a 7" center fin?
A 7" center fin is ideal for mid-length surfboards and 2+1 setups where you want stability without slowing the board down.
Where should I place the center fin in the box?
Moving the fin forward loosens the board, while sliding it toward the tail increases hold and drive.
Is Pro Glass better than honeycomb for a center fin?
Most surfers prefer solid fiberglass for center fins because it provides a more planted and predictable feel.
Can this be used as a single fin?
Yes — but it works best as the center fin in a 2+1 setup. Single-fin longboards usually run 8"–10" center fins.
