Effects of Alcohol

The effect of alcohol is increased by the natural stressors placed on your body while boating. Also, alcohol causes dehydration of your body. It takes less alcohol, combined with stressors, to impair an operator's ability to operate safely. Research has proven that one-third of the amount of alcohol that it takes to make a person legally intoxicated on land can make a boater equally intoxicated on the water.

  • Alcohol depresses the central nervous system, affects judgment, and slows physical reaction time. Most people become impaired after only one drink.
  • Alcohol makes it difficult for you to pay attention and perform multiple tasks. For example, it will be more difficult for you to keep track of two or more vessels operating in your area. This could become critical if you are placed in an emergency situation and must make a sudden decision.
  • Alcohol can reduce your ability to distinguish colors, especially red and green.
Don't Drink and Boat!
The best thing you can do for your safety and the safety of your passengers and other boaters is simple—
Don't drink and boat!
Alcohol Impairment

Alcohol impairment increases the likelihood of accidents—for both passengers and vessel operators. Always designate non-drinking boaters to operate the vessel and to act as an observer if your group plans to consume alcohol. Do not allow your skipper to operate if he or she is drinking. Alcohol is a major contributor to boating accidents and fatalities.

Drinking while boating is a choice. The best way to minimize the risk of an accident is to make the wise choice—Don't drink and boat!
