ALCOHOL ON BOATS: Is it legal to drink alcohol while boating in San Diego county or in California waters?
While it isn't illegal to drink alcohol on a boat in California waterways, it is against the law to operate a vessel while under the influence of intoxicating liquor or drugs. The blood alcohol limit for boating is the same as that for driving a car - 0.08%. If you are convicted of Boating Under the Influence (BUI), the Department of Motor Vehicles may suspend or revoke your vehicle driver's license for up to five years and you may be fined up to $1,000. More importantly, alcohol consumption by the vessel operator or passengers is a factor in approximately 25% of all fatal motorboat accidents in California.
