Why is it preferable to slow down in the event of a potential collision?

Slowing down in the event of a potential collision is essential because it significantly reduces the speed at which two vessels may collide, thereby lessening the impact and damage if a collision does occur. When vessels move at high speeds, the force of the collision increases, which can lead to severe damage to both vessels involved, posing safety risks to the crew and passengers, and causing environmental harm.

While the other options present valid considerations—such as avoiding contact altogether, preventing capsizing, and allowing time for decision-making—these aspects do not directly address the consequences of a collision in terms of reducing damage. Slowing down serves as a critical risk mitigation strategy that directly impacts the severity of a potential collision, making it a vital action to take in such scenarios.
