Which of the following increases the risk of accidents while boating?

Operating under the influence of alcohol significantly increases the risk of accidents while boating. Alcohol impairs judgment, coordination, and reaction times, which are critical for safe navigation and operation of a boat. Just as it does when driving a vehicle, alcohol consumption can lead to poor decision-making and a reduced ability to respond to sudden changes in the boating environment, such as waves, other vessels, or obstacles in the water.

Boating requires a high level of concentration and the ability to quickly assess and react to various situations. When an operator is under the influence, their ability to perform these tasks effectively is compromised, which can easily lead to collisions, capsizing, or other dangerous situations on the water. This is why laws and regulations, including those in California, strictly prohibit operating a boat while under the influence of alcohol or drugs.

In contrast, using safety equipment, keeping a safe distance from other vessels, and having a designated lookout are all practices that enhance safety on the water and actively work to prevent accidents.
