 A generally narrow board with small variance in design, it almost always has three fins, a pointed nose, a squash tail, and is approximately the height of the rider.This basic style of board, with many small modifications, has been the dominant craft since the 1980s and is still the approximation of the modern professional surfboard.In 21st century professional surfing it has slowly become shorter and wider, with a more rounded nose and sometimes 4-fins (rarely 2-fins and never 1-fin), although non-professionals still regularly mix and match all those options based on personal taste.
