Twin Fins in Australia: When They Arrived and Why They Stuck
The twin fin didn't just arrive in Australia; it blew the doors off a single-fin culture that had gone stale, and it never really left.
The Short Answer
Before 1977, most Australians were wrestling single fins. They were beautiful but hard to turn in the small, gutless waves that make up 80% of our surfing days. Then Mark Richards (MR) refined the twin fin in Newcastle, won four world titles, and proved that having two fins was the key to speed and "skatey" performance.
While the thruster eventually took over the competition world, the twin fin stuck around because it’s fundamentally more fun. It’s faster across flat sections, looser off the top, and turns a mediocre beach break into a playground. In Australia, where we have everything from Noosa peelers to Burleigh points, the twin fin is the "second board" every surfer eventually buys.
| Feature | Single Fin | Twin Fin |
|---|---|---|
| Primary Feel | Stable & Smooth | Fast & Loose |
| Turning Radius | Long & Sweeping | Tight & Snappy |
| Paddle Power | Good | Excellent |
| Wave Type | Clean & Hollow | Small to Head-high |
Newcastle was the ground zero
In the winter of 1977, Mark Richards was frustrated. He’d seen the "fish" designs in California—short, wide, and thick—but they weren't quite right for the high-performance turns he wanted to do. He went back to his shaping bay in Newcastle and combined the speed of the twin-fin setup with a more refined, performance-oriented outline.
The result was the "Free Ride" twin fin. When MR took it to Hawaii and started out-surfing the world on boards that looked "too small" for the waves, the world noticed. But back home in Australia, it sparked a revolution. Suddenly, every grommet in the country wanted a board with two fins and a bright spray.
It handles the "average" Australian day
The reason the twin fin stuck in Australia isn't just nostalgia. It’s geography. Most of us aren't surfing 6-foot Kirra every day. We’re surfing 2-foot beach breaks with multiple sections and not much push.
A twin fin has no centre fin to create drag. This means as soon as you stand up, the board wants to go. It generates its own speed. In Australia, "making the section" is the difference between a 10-second ride and a 2-second one. The twin fin is the ultimate section-maker.
The modern resurgence is about feel, not trophies
For a long time, the twin fin was seen as a "retro" choice—something you rode if you wanted to look like you were in a 70s movie. But riders like Asher Pacey changed that. They showed that you can surf a modern twin fin with incredible speed and flow without it looking "old."
Modern twin fins have better foils and more refined shapes. They aren't the "spinning out" disasters of the early 70s. When you pair a modern "upright" twin fin with a performance board, you get a setup that is fast, responsive, and incredibly rewarding to ride.
The Takeaway
If you’ve only ever ridden a thruster, you’re missing out on the easiest speed boost in surfing. A twin fin setup changes the way you read a wave—you stop fighting for speed and start using it.
Try an upright twin for that tight, snappy pivot, or a keel if you want to draw long, fast lines. Either way, you’re tapping into a design that defined Australian surfing for a reason: it works when the waves aren't perfect.
Newcastle gave us the blueprint, but the beach breaks keep it alive.
