Young Surfing Girl

The modern shortboard began life in the late 1960s and has evolved into today's common thruster style, defined by its three fins, usually around 6 to 7 feet (1.8 to 2.1 m) in length. The thruster was invented by Australian shaper Simon Anderson.
Midsize boards, ten called funboards, provide more maneuverability than a longboard, with more floation than a shortboard. While many surfers find that funboards live up to their name, providing the best both surfing modes, others are critical.
"It is the happy medium mediocrity," writes Steven Kotler. "Funboard riders either have nothing left to prove or lack the skills to prove anything."
There are also various niche styles, such as the Egg, a longboard-style short board targeted for people who want to ride a shortboard but need more paddle power. The Fish, a board which is typically shorter, flatter, and wider than a normal shortboard, ten with a split tail (known as a swallow tail). The Fish ten has two or four fins and is specifically designed for surfing smaller waves. For big waves there is the Gun, a long, thick board with a pointed nose and tail (known as a pin tail) specifically designed for big waves.
