C. Rule 3: General Definitions

• Defines key terms used throughout the Rules, such as:
  • Vessel: Includes every description of water craft used or capable of being used as a means of transportation on water
  • Power-driven vessel: Any vessel propelled by machinery
  • Sailing vessel: Any vessel under sail, provided that propelling machinery, if fitted, is not being used
