The primary purpose of the "Rules of the Road" in vessel navigation is to provide regulations to prevent collisions. These rules are established to create a standardized framework that helps navigators understand their responsibilities while at sea. They ensure that all vessels operate safely and efficiently by defining right-of-way scenarios, signaling requirements, and other navigational practices.

By adhering to these rules, mariners can make informed decisions that promote safe interactions between vessels, thereby minimizing the risk of accidents and collisions. This is vital for protecting not just the vessels and crew, but also the environment and other maritime interests.

Although speed limits, docking procedures, and maintenance schedules are important aspects of maritime operations, they do not encompass the fundamental purpose of the "Rules of the Road." The focus is specifically on collision avoidance and safe navigation, making option B the most accurate answer.
