In the late 1980s and early 1990s, Curdin Morell experienced one of the most successful careers in Swiss bobsledding history. He won back-to-back World Championships in the four-man event in 1989 and 1990, alongside Bruno Gerber, Lorenz Schindelholz, and Gustav Weder. At the 1991 edition, the quartet slipped to second place, but Morell and Weder also earned silver in the two-man. Morell also found success in the four-man at the European Championships, coming in third in 1988 (with Silvio Giobellina, Urs Salzmann , and the non-Olympian Celest Poltera) and 1990 (alongside Gerber, Schindelholz, and Weder), and winning in 1991 (again with Gerber, Schindelholz, and Weder). Morell’s final stop was the 1992 Winter Olympics, where Gerber was replaced on the team by Donat Acklin. This new quartet was taken off guard by a surprising Austrian victory and finished third in the four-man. Morell retired from active competition shortly after the Games.
