The International Melges 24 Class Association World Council meets annually. It comprises representatives of each of the National Melges 24 Class Associations plus representatives from the Class builders. The IMCA World Council is responsible for electing an IMCA Executive Committee, which takes charge of the day-to-day management of the class on the World Council's behalf.

The IMCA Executive Committee comprises a Chairman, two Vice Chairmen, the Secretary, the Treasurer and two Ordinary Members. In addition the IMCA Executive Committee currently employs four part time professional staff to assist them in the management of the class (David Chivers, Hank Stuart, Fiona Brown and Justin Chisholm). These professional staff members have no voting rights.
