Law enforcement officers joined Gov. Nathan Deal at the Laurel Park Boat Ramp on Wednesday to deliver the message that a blood alcohol content of .08 is the law of the land and the water. New boating under the influence laws that took effect Wednesday lower the legal limit of blood alcohol to .08 percent for someone operating a water vessel — the same standard for operating an automobile — and imposes escalated penalties for repeat offenders similar to driving under the influence laws.
