Which chapter of the COLREGs contains the general rules?

The general rules of the COLREGs are indeed found in Part A. This section establishes the fundamental principles that govern vessel navigation and apply universally to all mariners. These general rules set out critical guidelines, such as the responsibilities of vessels in various situations, whether they are under sail or power, and detail how they should interact to avoid collisions.

Part A specifically addresses the duties of all vessels, ensuring that the mariners adhere to safe practices right from the outset of their encounters at sea. This lays the groundwork for the more detailed rules found in the subsequent parts, which cover specific navigation situations, such as crossing, overtaking, and being at anchor, thereby highlighting the importance of understanding Part A as foundational guidance for safe maritime operations.
