What is the alcohol limit for boaters under 21?

In the United States, the alcohol limit for boaters under 21 is typically set at a blood alcohol concentration (BAC) of 0.00%. Most states enforce a zero-tolerance policy for underage drinking and operating a boat, meaning that any detectable level of alcohol can lead to penalties. It's essential for young boaters to remain sober while on the water to ensure safety for themselves and others. Always check local laws, as regulations can vary by state.
