Swallow tail refers to a split tail shape that increases lift, speed, bite and release by dividing the tail into two points. The cut-out reduces surface area while maintaining outline width, improving drive, quick transitions and pivot in small to medium waves.
Its behaviour depends on tuned tail rocker, coherent outline curves, refined rail design and the interaction with bottom contours, including single, double or vee transitions that tune release and grip between the two tail points.
Swallow tail performance traits
- Added lift and speed in weaker waves
- Bite and hold from the dual tail tips
- Fast rail-to-rail transitions
- Clean release for tight directional changes
Swallow tails are common in fish surfboards, hybrids and small-wave performance boards, where acceleration, looseness and responsiveness define the riding experience. Shapers refine swallow tails through tuned outlines, foil balance and construction choices that maintain responsiveness, feedback and control.
