Which of the following is NOT a major responsibility of a boat operator?

Making rapid maneuvers is not considered a major responsibility of a boat operator because safe boating practice emphasizes the importance of maintaining control and operating a vessel in a predictable and responsible manner. Rapid or erratic maneuvers can lead to dangerous situations, including collisions or capsizing, and thus should be avoided unless absolutely necessary for safe navigation.

In contrast, practicing good seamanship involves handling the boat with skill and care, which contributes to overall safety. Keeping a proper lookout is critical for avoiding obstacles and other watercraft, ensuring that the operator can react appropriately to changing conditions. Maintaining a safe speed is also essential, as it allows for better reaction time and reduces the risk of accidents. These responsibilities prioritize the safety of the boat, its passengers, and other individuals on the water.
