Few things beat the open waters with a cold beer in your hands with friends.  However, sometimes the partying can go too far and someone might drink too much.  Every state has a law against Boating Under the Influence which makes it illegal to operate a boat or personal watercraft, like a jetski, while under the influence of alcohol or drugs.  If you are stopped for Boating Under the Influence you could incur heavy monetary fines, increased insurance rates, and even jail time.  Both federal and state officers can pull you over if they think you may be under the influence of alcohol or drugs.  Police officers can even create checkpoints on the water to check each driver, some states will allow officers to come onto your boat or personal watercraft while other states will require probable cause in order to board your vessel.  If you are given a breathalyzer test and you are above the legal limit, which is usually .08 or .1 percent, then you are likely to be found guilty of Boating Under The Influence.
