5' 11" Heritage Twin Fish
5' 11" × 20½" × 2½" – Volume 32.69L
Vintage Speed meets Modern Precision
The 5' 11" Twin Fish is a masterclass in "fun," bringing that classic 70s glide into the modern era. Designed for surfers who want to fly across flat sections and feel that unique twin-fin "skatey" freedom, this board is built for speed and flow. At 32.69L, it offers a refined, performance-oriented feel that allows for rail-to-rail surfing without losing the iconic paddle power fish shapes are known for.
The magic of this shape lies in the advanced bottom contour. We've utilised a single concave under the front foot that transitions into a double concave through the fin area. This design breaks up the wider tail of the fish, preventing it from feeling "sticky" and helping to direct water flow directly through the fins. The result is increased acceleration in small waves, extra lift, and better rail-to-rail responsiveness for those loose, iconic twin-fin turns. Whether you're a shortboarder looking for a "groveler" or an intermediate surfer wanting to transition into a more stylish, flowing ride, the Heritage Twin Fish is a quiver essential.
Available in Bottle Green, Sky Blue or Duck Egg.

The Circle One Heritage Range
Step back in time without sacrificing the tech. Our Heritage range is a tribute to the golden era of surfing, using modernised shapes by the legendary Jeff Townsley, the founder of Circle One and an OG of the British shaping scene since the 70s.
These boards feature a Premium Epoxy Resin Tint finish. This traditional technique creates a deep, vibrant, and translucent colour that is "in" the resin, not just painted on. Because each board is hand-laminated and hand-finished, the tint creates unique colours and sometimes patterns, ensuring your board is a one-of-a-kind work of art. Combined with modern FCS II fin boxes (the most versatile system on the market), these boards offer vintage soul, wave catching ease combined with the reliability and performance of today's best materials.

Frequently Asked Questions
What type of waves is the Heritage Twin Fish designed for?
The Heritage Twin Fish is at its best in small to medium surf — knee to overhead — particularly in weaker, slower waves where a standard shortboard can feel sluggish. The twin-fin setup and fish outline generate speed where other boards struggle, making it an excellent choice for the kind of average beach break conditions that make up the majority of UK surf days. It also handles cleaner, more powerful surf well, where the twin-fin freedom really comes into its own.
Is this board suitable for beginners?
The Heritage Twin Fish is best suited to intermediate and advanced surfers. At 32.69L it has good volume for its length, but the twin-fin setup and performance-oriented shape rewards surfers who already have solid fundamentals — bottom turns, rail-to-rail transitions, and an understanding of how to generate speed. If you're still developing the basics, one of the longer boards in the Heritage Range will serve you better to start.
What is the difference between a twin fin and a thruster?
A thruster has three fins — two side fins and a centre fin — which provides drive, hold, and directional stability. It's the most common setup in modern surfing. A twin fin has just two side fins and no centre fin, which removes the drag of the centre fin and gives the board a looser, faster, more free-flowing feel. Twin fins excel at generating speed and producing that distinctive "skatey" pivot off the tail. They require a slightly different surfing style — more drawn-out, flowing turns rather than sharp, vertical manoeuvres — but the reward is a unique sensation that's hard to replicate on a thruster.
What volume should I choose for a fish surfboard?
The Heritage Twin Fish comes in at 32.69L, which suits intermediate to advanced surfers in the mid-weight range. As a general guide, fish surfboards are typically ridden with slightly more volume than a standard shortboard of the same length — the wider outline and fuller template mean the extra float doesn't compromise performance. If you're unsure whether this volume is right for your weight and ability, get in touch and we'll help you work it out.
Which FCS II fins work best with this board?
We've hand-picked specific FCS II fin options for the Heritage Twin Fish based on our knowledge of how this board is shaped and how it performs. There's a wide range of FCS II twin fin sets available, but our recommendations represent what we genuinely believe works best with this particular shape. You'll find them via the fin upgrade buttons above — a standard option and a premium option depending on your preference and budget. If you'd like further guidance, feel free to get in touch.
What is a fish surfboard?
A fish surfboard is a short, wide, thick shape with a swallow tail, originating from the knee-board designs of the early 1970s in California. The wide nose and tail, combined with generous volume for the length, make fish shapes exceptionally fast and paddle-friendly. They became popular as a practical alternative to longer boards in small surf and have remained a staple of the modern quiver ever since. The Heritage Twin Fish takes that original template and refines it with a modern bottom contour for improved performance across a wider range of conditions.
