Mitchell, 32, joins the World Tour after more than six years working at ISAF, the world governing body for the sport.
He brings to the series a technical understanding of regattas, including the umpiring system and racing rules. He was also a race officials manager, working with the Appointments Working Party to appoint race officials to ISAF events.
Mitchell spent most of his time at ISAF in the events department, with responsibility for the World Match Race Rankings, sailor classification system and the Match and Team Racing World Championship regattas.
The appointment comes shortly after the World Tour and ISAF signed a Memorandum of Understanding, which outlines the steps to form a long-term partnership.
