Advanced maneuver during which the surfer comes up from a crouch to stand at full height while inside the tube. The ultimate form of tuberiding. Hawaii's Gerry Lopez is often credited with inventing the stand-up tube at Pipeline in the early 1970s. Variation include the arched back, upraised arms, and hand-behind-the-back. Shaun Tomson, Sunny Garcia, Kelly Slater, Andy Irons, and Jamie O'Brien are among the sport's best-known stand-up tuberiders.
