British number one Zoe Gillings missed out on a fourth consecutive final at the penultimate round of the World Cup in Stoneham, Canada, on Tuesday.
The Manx snowboarder qualified fifth fastest for Wednesday's finals but was knocked-out in the semi-final.
She went on to finish third in the small final. "I am disappointed not to reach the final but I am happy with my performance," said the 26-year-old.
The competition was won by the Olympic gold medallist Maelle Ricker.
It was the Canadian snowboarder's first World Cup victory since suffering a broken hand and injured shoulder in a crash at the 2011 World Championships in Spain.
French snowboarders Nelly Moenne Loccoz and Deborah Anthonioz finished second and third.
World Cup points leader Dominique Maltais was seventh overall after winning the small final ahead of Bulgaria's Alexandra Jekova and Gillings.
The format for the World Cup event has taken a dramatic change this year, with 24 athletes now qualifying for the heats instead of 16, and each heat featuring six athletes instead of four.
