A "Navigation Rule" refers to the regulations that govern the conduct of vessels at sea, ensuring safety and efficiency in maritime operations. These rules are designed to prevent collisions and promote safe navigation by establishing protocols that all mariners must follow while on the water. Examples include the International Regulations for Preventing Collisions at Sea (COLREGs), which detail responsibilities for vessels on the water and outline navigational practices.

The other choices focus on different aspects of maritime operations. Procedures for docking a vessel safely relate more to operational techniques rather than legal regulations. Guidelines for vessel maintenance and repair address the upkeep of a vessel but do not encompass the regulatory framework that Navigation Rules provide. Policies for crew training and certifications focus on the qualifications of personnel rather than the conduct of the vessels themselves. Thus, while all play important roles in maritime safety and operations, only the regulations that govern the conduct of vessels at sea accurately define what a "Navigation Rule" is.
