Accurate measurement is essential for effective Yacht Rating systems. The performance characteristics of each rated yacht are determined by the provided measurements. Inaccurate data results in incorrect ratings, which can impact the outcomes of races and regattas. This course is designed to outline and develop the competencies necessary for successful measurement practices.

The curriculum covers comprehensive aspects of measurement for both IRC and ORC systems. Key topics include:

• IRC Rules and Policies
• ORC Rules and Policies
• Measurement Methodologies
• IRC Measurement Procedures
  • Rig
  • Sails
  • Weighing
