What is a "surfboard"?

A surfboard is a long, flat board used in surfing to ride waves in the ocean. It is usually made of lightweight materials, such as fiberglass, and comes in different shapes and sizes depending on the style of surfing. Surfboards are designed to float on water and provide stability while allowing the surfer to balance and maneuver over waves. The rider stands on the board, using their body movements to control direction and speed as they ride the waves. Surfboards are essential for surfers and are used in both recreational and competitive surfing.
