What is illegal to do if your blood alcohol concentration (BAC) is above the legal limit?

Operating a vessel with a blood alcohol concentration (BAC) above the legal limit is illegal because it significantly impairs a person's ability to navigate safely. Just like with motor vehicles, consuming alcohol affects judgment, coordination, and reaction times, which are critical for safe boating. The legal limit is established to promote safety on the water, as impaired operators increase the risk of accidents, collisions, and injuries.

Engaging in activities like anchoring, parking, or fishing from a vessel may not be directly impacted by impairment in the same way that operating the vessel is. Therefore, it remains crucial for boat operators to remain sober to ensure not only their safety but also the safety of others on the water.
