Mixing alcohol and boating is far more dangerous than most people realize. Fatique, sun, wind and the motion of a boat intensifies the effect, leaving you with a longer reaction time, poorer fine motor skills and impaired judgement. This means that even in moderation, drinking and boating is not a good idea.
So, the next time you're out on the water and need a drink... consider something that's refreshing and won't impair your ability to operate your boat. Consider fruit juices, a favoured soft drink or better yet - water.
