A '''surfboard''' is a narrow plank used in [[surfing]]. Surfboards are relatively light, but are strong enough to support an individual standing on them while riding an ocean wave. They were invented in ancient Hawaii, where they were known as ''papa he{{okina}}e nalu'' in the Hawaiian language, and were usually made of [[wood]] from local trees, such as [[Acacia koa|koa]]. They were often over {{convert|15|ft|cm|order=flip|abbr=on|sigfig=2}} in length and extremely heavy.<ref>{{Cite web|publisher=[[Bernice P.

Modern surfboards are made of [[polyurethane]] or [[polystyrene]] foam. Unlike soft top surfboards, hard top surfboards are also covered with layers of [[fiberglass]] cloth, [[polyester]] or [[epoxy resin]]. The result is a light and strong surfboard that is buoyant and maneuverable. Recent developments in surfboard technology have included the use of [[carbon fiber]] and [[kevlar]] composites, as well as experimentation in biodegradable and ecologically friendly resins made from organic sources.<ref>{{Cite news|url=https://www.wavetribe.com/pages/bio-resin-vs-poly-resin|title=Bio Surfboard Resin vs Poly Surfboard Resin|work=Wave Tribe |access-date=2018-01-18|language=en}}</ref><ref>{{cite web|url=https://thesaltsirens.com/best-soft-top-foam-surfboards/|title=The Best Soft Top Foam Surfboards}}</ref>  Each year, approximately 400,000 surfboards are manufactured.<!-- Citation needed. -->
