What is the effect of alcohol consumed while boating?

• A. It has no effect on safe boating
• B. It has the same effect whether on land or water
• C. It improves coordination
• D. It enhances night vision

Answer: (B)

Alcohol slows your thinking, dulls judgment, and impairs balance, coordination, and reaction time. These effects don’t disappear just because you’re on a boat—the impairment is the same whether you’re on land or on the water. On water, the boat’s motion plus the need to respond to other vessels and changing conditions makes those impairments even more dangerous, increasing the risk of collisions, capsizing, or falling overboard.

So the best way to understand it is that alcohol affects the same functions in the same amount, no matter the setting, which is why operating a vessel after drinking is unsafe and often illegal. The other ideas—that it has no effect, that it improves coordination, or that it enhances night vision—are incorrect.
