Adding colour and design

A twin fin surfboard has two fins rather than the three you'd find on a thruster. Removing the centre fin completely changes how the board moves — you get a faster, looser, more flowing feel, with a lot of release off the tail. Twin fins generate speed quickly, particularly in smaller and mushier waves, and reward a smooth, rail-to-rail style of surfing. They're not as tight or controlled in steep, critical sections as a thruster, but in the right conditions they're genuinely hard to beat for fun.

Both are twin fin shapes, but the tail design is the key difference. A fish has a swallow tail — a distinctive V-shaped split that adds width and gives the board speed and release. A twin pin has a pulled-in pintail, which gives much more hold and control in cleaner, hollower, and more powerful waves. If you surf mostly smaller, mushier conditions, a fish is the better call. If you want the twin fin feeling but need more hold when the surf is better or gets punchy/hollow, a twin pin is the shape for you.

Retro fish surfboards draw from the twin fin shapes that were popular in the late 70s and early 80s — wider, flatter in rocker, with more volume and a looser, skatier feel than modern performance boards. They were the boards that started the twin fin revolution and remain excellent everyday surfboards, particularly for UK conditions. A modern performance fish takes those same principles but refines the outline and rocker slightly for a more versatile ride — faster off the tail, tighter in turns, while keeping the fun, flowing character of the classic shape.

Fish and twin fin surfboards are at their best in small to medium, slower or mushier waves — exactly the conditions that make up the majority of UK surf. The flatter rocker and wide outline generate speed even when the wave isn't giving much, and the twin fin setup makes turns feel fluid and effortless. They're a popular alternative to a groveller shortboard on smaller days, and many surfers find them significantly more fun to ride in chest-high or under surf than a performance shortboard would be.

Twin fins and fish surfboards are generally suited to high intermediate and advanced surfers. The loose, fast feel of a twin fin rewards surfers who have the technique to use that speed and release — in less experienced hands, the lack of a centre fin can feel unpredictable. That said, a bigger fish or mid-length twin fin with plenty of volume can work well for improving surfers who are already comfortable on a mid-length and want to explore a different style of surfing.

A big fish is a longer, higher-volume version of the classic fish shape — typically in the mid-length range — that brings the twin fin feel to a wider range of conditions and surfer sizes. Our big fish models range from small to medium wave mid-length twin fins through to bigger rocker versions built for the larger, rolling swell the UK sees in autumn and winter. A long fish surfboard is a good option for heavier surfers who want the twin fin experience, or anyone wanting a floaty, fun mid-length with twin fin drive.
