Partnership with Bourne

On April 20, 1991, Kraatz began skating with Shae-Lynn Bourne, who had been a pair skater until that time. Bourne tried out with him in Boucherville, Quebec, on the suggestion of a coach, Paul Wirtz.^[4]

During their career, Bourne/Kraatz were coached at various times by Tatiana Tarasova, Natalia Dubova, Uschi Keszler, Marina Klimova and Sergei Ponomarenko, and Nikolai Morozov.

They won their first medal at a World Championships in 1996. According to figure skating writer and historian Ellyn Kestnbaum, their performance emphasized the athleticism of ice dance instead of the traditional ballroom style approach.^[5]

For the 1996—1997 season, "in response to suggestions that they increase the complexity and danciness of their free skate",^[5] they used music from the 1956 movie High Society, in which they used a mostly athletic and non-narrative approach with mostly quickstep and swing rhythms that emphasized the soft knees they were known for. Kestnbaum also stated, "Only their costumes and the occasional reliance on traditional dance holds suggested any gendered identity for each partner".^[5] Their choice of rhythms allowed them to continue to emphasize their technique and athleticism while following the sport's rules and guidelines, but without depending upon "the erotic narratives attached to other ballroom rhythms".^[5] As a result, both partners were able to present themselves as athletes capable of executing positions and able to support each other's weight, while following the ice dance traditions of "male-female couplehood".^[5] in this way, along with their choice of dance holds, rhythms, and costumes, they were able to establish their performance within the sport's ballroom dance traditions.^[5]

For the 1997–98 season, their free dance was modeled after Riverdance, with footwork instruction provided by Riverdance lead dancer Colin Dunne. Bourne/Kraatz became known for their deep edges and soft knees. They were credited with perfecting and popularizing the hydroblading technique. The program included a great amount of up-and-down hops in place on their toes and side-by-side footwork.^[6]

In 2000, Bourne and Kraatz choreographed their own free dance program; it was first season vocal music was allowed in ice dance, so their music was set to vocal selections by Harry Connick, Jr.^[7] They missed the 2000 Four Continents and 2000 World Championships due to Bourne's knee surgery.^[8] In spring 2000, they changed coaches, moving to Tatiana Tarasova and Nikolai Morozov in Newington, Connecticut.^[9]

Bourne/Kraatz withdrew from their 2002 Grand Prix events due to Bourne's injury.^[1] They won their tenth Canadian national title and their third Four Continents title. Bourne/Kraatz went on to become the first World champions in ice dancing from North America, winning gold at the 2003 World Championships in Washington, D.C. They retired from competition at the end of the season.

On October 21, 2003, they announced the end of their partnership; while Bourne enjoyed show skating, Kraatz said he wanted "to experiment with other things and follow up on other dreams that I have".^[10] In January 2007, they were inducted into the Skate Canada Hall of Fame.^[11]

Kraatz represented CPA Boucherville in Boucherville, Quebec.^[1]

Later career

After retiring from skating, Kraatz studied marketing and began working at a marketing agency in Yaletown, British Columbia.^[2]

In 2005, Kraatz joined the B.C. Centre of Excellence.^[11] He went on to coach Allie Hann-McCurdy / Michael Coreno,^[11] Carolina Hermann / Daniel Hermann,^[12] and Danielle O'Brien / Gregory Merriman.^[13] In the winter of 2012–13 season, he switched to coaching hockey players.^[2]
