Young Surfing Girl

Surfing can be done on various equipment, including surfboards, longboards, Stand Up Paddle boards (SUP's) , bodyboards, wave skis, skimboards, kneeboards and surf mats.
Surfboards were originally made solid wood and were large and heavy (ten up to 12 feet (3.7 m) long and 100 pounds (45 kg)). Lighter balsa wood surfboards (first made in the late 1940s and early 1950s) were a significant improvement, not only in portability, but also in increasing maneuverability.
Most modern surfboards are made polyurethane foam (PU), with one or more wooden strips or "stringers", fiberglass cloth, and polyester resin. An emerging board material is epoxy (EPS) which is stronger and lighter than traditional fiberglass. Even newer designs incorporate materials such as carbon fiber and variable-flex composites.
