Circle One Heritage 5'11" Twin Keel Fish Surfboard
Vintage Speed Meets Modern Performance
The Circle One Heritage 5'11" Twin Keel Fish captures everything surfers love about classic 1970s fish surfboards while incorporating modern shaping refinements that make it faster, livelier and more versatile than ever.
Hand-shaped by legendary British surfboard designer Jeff Townsley, this beautifully crafted twin-fin delivers effortless speed, incredible drive and the unmistakable loose, skate-inspired feeling that has made fish surfboards a favourite for generations.
At 5'11" x 20½" x 2½" with 32.69 litres of volume, the Heritage Twin Fish offers excellent paddle power without sacrificing responsiveness, making it the ideal choice for surfers who want to maximise speed, flow and fun in everyday waves.
Available in Bottle Green, Sky Blue and Duck Egg, every board features a hand-finished epoxy resin tint, ensuring every Heritage Twin Fish is completely unique.
Why You'll Love It
The Heritage Twin Fish has been designed to generate effortless speed where other surfboards slow down.
Its wider fish outline creates lift and paddle power, while the carefully engineered single concave flowing into a double concave channels water efficiently through the twin fins. The result is rapid acceleration, exceptional down-the-line speed and incredibly smooth rail-to-rail transitions.
Whether you're flying across soft summer waves, carving open faces or looking for a playful small-wave performance board, the Heritage Twin Fish delivers speed with style.

Frequently Asked Questions
What is a Twin Fish surfboard?
A Twin Fish is a shorter, wider surfboard with a distinctive fish tail and twin-fin setup. It's designed to generate speed effortlessly, paddle easily and deliver smooth, flowing turns with a playful, skate-like feel.
Is the Heritage Twin Fish suitable for beginners?
This board is best suited to intermediate and advanced surfers. While it paddles well, the lower volume and responsive twin-fin design are better suited to surfers with solid pop-up and turning skills.
What makes a twin fin different from a thruster?
Twin fins create less drag than a traditional thruster, making the board feel faster, looser and more responsive. Thrusters generally offer more control in steeper, more powerful waves, while twin fins excel in smaller surf and flowing lines.
What waves does the Heritage Twin Fish perform best in?
The Heritage Twin Fish shines in knee-high to head-high surf, especially softer beach breaks and point breaks where speed generation is key. It also performs confidently in overhead waves thanks to its refined bottom contours.
Which fins should I use?
The board features FCS II twin fin boxes, and we recommend one of our hand-selected FCS twin templates to maximise speed, drive and the classic flowing feel this surfboard was designed to deliver.
