Boating Under the Influence is incredibly dangerous, and never worth the risk.
As you can see above, drinking while boating:
Impacts cognitive ability
Impairs judgement
Makes balancing difficult
Reduces coordination
Slows reaction time &
Decreases vision

With operating a boat already being a challenging task, adding alcohol to the mix is... just plain stupid.

When you see a statistic like this, it becomes pretty clear that BUI simply isn't an option.
Please be a smart, responsible person. Never operate a boat under the influence of alcohol.
