Types of tail shapes
Square tails help you plane easily over flat or weaker sections. This is due to the extra surface area and volume in the tail of the board. It also increases stability on a wave. An example of this shape is the Dahlberg RDS2.
Allows a perfect balance of maneuverability, whilst enhancing stability. This is because it is a combination of a square and a round. It assist a rider with tighter turns, and fitting into the pocket of the wave. An example of this shape is the Deathless Standoid.
Also allows a rider to plane over weaker sections, and offers a ‘performance’ feel. A round tail is designed to give you more hold, compared to a square, especially when surfing in big waves or steep barrels. An example of this shape is the Webber Sonic.
The main feature of a swallow tail is that it offers stability from the two points at the end of the rails. These points are also helpful in making turns, when transitioning from rail to rail. Mostly found in fun boards for small waves. An example of this shape is the Diverse Astral Tracer.
This shape is ideal for barrel riding, as it holds up well in the steep face of a wave. The pin is a drawn in version of a round tail, which assists in surfing more extreme conditions. An example of this shape is the Free Flight Col Smith.
