Sjoerd Steven Vollebregt (born 10 December 1954, in Leiden) is a sailor from the Netherlands who represented his native country at the 1976 Summer Olympics in Kingston, Ontario. With twin brother Erik Vollebregt as helmsman, Vollebregt finished 14th in the Sailing at the 1976 Summer Olympics – Flying Dutchman. Since in 1980 the Netherlands boycotted the Moscow Olympics, Vollebregt represented his National Olympic Committee under the Dutch NOC flag in the Flying Dutchman. Again with his brother as helmsman, he took 7th place.
After the 1980 Olympics Vollebregt started a new Olympic campaign for the 1984 Olympics crewing in the Soling together with Gijs Evers and his older brother Peter Vollebregt as helmsman but finally failed to qualify.
During the selection for the Dutch Olympic Sailing Team for the 1976 Olympics a controversy emerged between twelve sailors and the selection committee chaired by André du Pon. Fred Imhoff and Heike Blok, two sailors hoping to be selected, filed suit, arguing that Frieda Vollebergt, the communications person for the sailing team, was partial: as mother of Erik, Sjoerd, and Peter Vollebregt, all candidates for the 1976 Olympic sailing event, she was accused for having a bias towards her children. In the end Imhoff and Blok lost the lawsuit and were removed from the 1976 selection. During this period Vollebregt's father, Jan Vollebregt, was president of the Koninklijk Nederlands Watersport Verbond (Dutch Yacht Racing Union).
Several countries did boycott the 1980 Summer Olympics, others like France did not go since they found the competition devaluated. As result only half of the expected fleet was present during the Olympic regattas.
