Whatcha got down there?

You can’t see it when you’re on a wave, but the fin beneath your board is what’s making your ride. Or not.

A surfboard fin, or skeg, is a hydrofoil mounted towards the tail of the surfboard designed to improve directional stability and control.

Fins provide a lateral lift in opposition to the water to stabilize the board’s trajectory allowing surfers to change direction by shifting their weight.

Fins weren’t introduced as standard on surfboards until somewhere around the 1930s, and they revolutionized both surfing and board design.

But that was just the start.

Fin configuration

Surfboard fins are designed to be fixed in various quantities and configurations, and come in many different shapes, sizes, and materials. There are, however, three basic categories:

Glass fins: fixed or permanent fins are fiberglassed onto the board.

This type of fin was mainly used on older model surfboards. On retro, classic or vintage surfboards, glass fins can be easily broken and are tough to repair. You’ll rarely find them on a new board.

Removable Fin Systems: In the early 90’s, three Australian surfers invented the fin control system (FCS). Since it went global in 1994, FCS has become the industry standard. The system is used by everyone from pros to everyday surfers allowing a wide range of fin designs and a platform to change the performance of the board – depending on conditions – by changing fins.

The most common types of fin used today, removable fins can be unscrewed from the board and be replaced by a different shaped fin, or moved around in the fin box to provide a different setup for variations in maneuverability and stability.

Removable fins have also streamlined the surfboard manufacturing process, making it easier to install fins and repair damaged fins.

There are two major suppliers of fin boxes, FCS and California’s Futures fins. They both offer a big variety of fins but you’ll need to replace your fins with those from the same manufacturer, as each system is a little different.

Flexible fins: The big upside of flexible fins is that they can’t cut you so they’re much safer and are used most rental boards to avoid liability. Every upside, of course, comes with a downside. The downside is that flexy fins lose a little in terms of performance. For beginning surfers, however, performance isn’t the number one issue.
