A surfing boom comprising a pipe of synthetic resin having a density of 1.4-1.6 g/cm3. The pipe is reinforced by a plurality of carbon fiber layers. In a first carbon fiber layer, fibers are oriented within an angle of 60 DEG -90 DEG to an axial direction of the boom. In a second carbon fiber layer, fibers are oriented within an angle of 30 DEG to the axial direction of boom.
