Modern stand up paddle surfing has its own Hawaiian roots as well. In the 1940s, surf instructors in Waikiki like Duke Kahanamoku and Leroy and Bobby AhChoy would take paddles and stand on their boards to get a better view of the surfers in the water and incoming swells, and from time to time they would surf the waves in themselves using the paddle to steer the board. Injured in a car accident that restricted him from swimming or kneeling, Bobby would stand up, cigarettes lashed to his arm, camera about his neck, and paddle into the surf zone shouting hints to others. His brother Leroy and father John would also stand up from time to time. And so Beach Boy Surfing was born.
