The Fish Revival: Redefining Speed and Flow in Modern Surfboard Design

Back in the day, if you paddled out on a fish you were either a kneeboarder on a wild tangent or a shaper who had been sniffing too much resin. For decades, the fish was a weird, stubby stepchild of the shortboard revolution, a strange little craft that seemed to have one trick: go fast in gutless, mushy slop. But something happened on the way to the point break. The fish, that old-school twin-fin sled from the late seventies, got a total goddamn renaissance. It didn’t just come back—it evolved, mutated, and now it’s one of the most versatile, rippable shapes in any quiver. This is the story of how the fish broke free from its retro cage and became a modern design masterpiece.

The original fish, pioneered by guys like Steve Lis and later refined by Skip Frye and the Campbell brothers, was all about speed in small waves. It had a swallowtail that looked like a snake’s tongue, a wide, almost bloated outline, and a low rocker that let it glide across flat sections like a hovercraft. But the early models were thick, heavy chunks of foam that lacked the drive to hold a rail on a steeper face. They were fun, sure, but they weren’t exactly high-performance. Fast forward to the early 2000s, and a new generation of shapers started asking a simple question: what if we took the fish’s speed and made it turn?

Enter the modern fish. The key innovation wasn’t the outline or the tail—it was the rail and the foil. Old-school fishes had a hard, 50-50 rail that was almost a straight edge, making them slidey and unpredictable on a critical drop. Modern shapers started adding a sharper, more defined rail with a gradual tuck, turning that stubby hull into a blade. They thinned out the nose and tail, reducing the foam volume while keeping the planing surface wide. This meant the board still generated ludicrous speed on the flat, but now it could bite into a vertical pocket and hold a turn like a proper shortboard. The swallowtail became tighter, with less release, giving you more control in the carve. Shapers like Tomo, Rusty, and Stretch began experimenting with vee bottoms, spiral vee, and even a little double concave through the back third, all designed to channel water flow and give the fins a cleaner bite.

The mass adoption of epoxy and carbon fiber construction was the cherry on top of the stoke cake. A modern fish built with a lightweight EPS core and a bamboo or glass stringer has a lively, springy feel that the old polyurethane bricks could never offer. You paddle easier, you pop up faster, and you maneuver with way less effort. Add in the fact that a lot of these boards are now glassed with a slightly softer flex pattern, and you’ve got a sled that absorbs chop and chatter while still transmitting every ounce of energy into a rail-to-rail snap. The fins evolved, too. Those old-school twin-fins could be finicky and prone to spinning out if you pushed too hard. Modern templates—like the upright keel with a small trailer, or the pivot-style thruster setup—give you the speed of a twin with the hold of a quad. It’s a cheat code for everyday waves, the kind of mushy, gutless lineup you paddle into at dawn when the tide is wrong and the wind is onshore.

The true innovation, though, is the philosophical shift. The modern fish is no longer a compromise board. It’s not a “groveler” for when the waves are waist-high. It’s a legitimate weapon for chest-to-head-high surf that lets you draw the longest, most drawn-out turns of your life. You can take a modern fish to a punchy reef and lay it on rail with the confidence of a thruster, but you’ll exit the pocket with way more speed and projection. It turns surfing back into a flowing, endless dance of acceleration and release, rather than a series of herky-jerky hit-and-spray maneuvers. The fish has become the ultimate expression of the soul surfer’s dream: ride every section, never stop moving, and let the wave do the heavy lifting.

So if you’re still paddling around on a standard shortboard that feels like a wet dog after three waves, maybe it’s time to catch the wave that’s already here. The fish isn’t just a retro fad—it’s a modern design that unlocked something primal. Speed. Flow. And the pure, unadulterated joy of a single, unbroken rail-to-rail arc. Go order one. Your stoke will thank you.

Start with your local waves and what you want to do. For most daily drivers and performance surfing, the thruster (3 fins) is your go-to—balanced and versatile. If you’re chasing speed in hollow waves or want insane drive off the bottom, try a quad (4 fins). It’s fast but can feel tracky. For a loose, retro, soul-carving feel on a smaller or mellow wave, a twin-fin (2 fins) is pure joy, though it can be slidey. Don’t be afraid to swap fins and experiment; your perfect feel is out there.

When it’s small and weak, you need a secret weapon—that’s the groveler. These boards are wider, flatter, and thicker than your standard shortboard, with a fuller nose and a squash or swallow tail. This design gives you maximum paddle power and planing surface to generate speed in mushy surf. They’re not for critical turns; they’re for generating fun where there seems to be none. Think of it as your small-wave cheat code to keep you stoked even on a summer day with knee-high slop.

It’s a weight and durability thing, for sure. Traditional polyurethane foam and fiberglass (PU/PE) boards have that classic flex and feel but can be fragile. Epoxy construction with expanded polystyrene (EPS) foam creates a lighter, stronger, and more buoyant board. They’re perfect for average conditions, as they paddle easier and can take a beating. Carbon fiber strips add next-level stiffness and pop for high-performance snaps. While purists still love the “glass” feel of a PU board, epoxy tech lets you surf longer with less fatigue.

They’re totally legit for certain breaks! The idea is that your frontside and backside turns are fundamentally different. An asym board has a different rail shape, fin setup, or bottom contour on your toe-side versus your heel-side. For a regular footer at a right-hand point break, it can make your backside (facing the wave) more drawn-out and your frontside (back to the wave) more snappy. It’s not an everyday board for everywhere, but for a specific wave you surf all the time, it can unlock a new level of flow.

Channels are those deep grooves running from the fins to the tail. They’re all about control in heavy, powerful surf. Think big, chunky waves like Pipeline. The channels act like the fins on an airplane’s wing, directing water flow and reducing side-slip when you’re taking off late or driving through a critical section. They give you extra hold and predictability when you absolutely cannot afford to slip out. You won’t find them on your small-wave board, but on a step-up or a gun, they’re a game-changer.

Rocker is the board’s bottom curve from nose to tail. More rocker helps in steep, hollow waves for tight turns and prevents nose-diving. Less rocker means more speed in flatter sections. Concave is the channel running along the bottom. Single to double concave helps channel water, creating lift and control. It’s like the board’s undercarriage engineering. A flat board with no concave would be a slippery sled, while too much rocker in small waves kills speed. Shapers blend these curves for specific wave types.
