What is an essential part of successfully navigating through heavy traffic?

Constantly adjusting speed according to conditions is essential for successfully navigating through heavy traffic because it allows a vessel to respond effectively to the dynamic nature of the environment. In heavy traffic, the presence of other vessels, potential navigational hazards, and changing weather conditions all demand that a coxswain remain vigilant and flexible.

By adjusting speed, the coxswain can maintain better control of the vessel, improve reaction time in case of sudden movements by other vessels, and ensure adherence to safe navigation practices. Slowing down may be necessary to enhance maneuverability and to give more time to assess the surroundings, whereas increasing speed may be appropriate when passage is clear. Each situation can differ significantly, so maintaining an adaptable speed is crucial for safety and effective navigation.
