Boating Under the Influence (BUI) Defense in California
Understanding Boating Under the Influence (BUI) in California
California's boating laws treat operating a vessel under the influence of alcohol or drugs similarly to driving under the influence (DUI). Under California Harbors and Navigation Code §655, it is illegal to operate any boat, jet ski, or watercraft while impaired by alcohol or drugs or with a blood alcohol concentration (BAC) of 0.08% or higher.
If you're arrested for boating under the influence, you face serious criminal penalties, loss of boating privileges, and potential impacts on your driver's license. Our team links your BUI case with the DMV hearing process and license reinstatement strategy.
At Walia Law Firm, our Bay Area DUI defense attorneys understand the complexities of California's BUI laws. We have over 20 years of experience defending clients in Alameda County, Contra Costa County, Santa Clara County, San Mateo County, and Marin County who face charges related to drunk boating, boating accidents, and DUI offenses.
California Boating Under the Influence Laws
A BUI charge in California can arise under several legal provisions:
- Harbors & Navigation Code §655(b): Makes it unlawful to operate a vessel while under the influence of alcohol or drugs.
- Harbors & Navigation Code §655(c): Establishes a 0.08% BAC limit for recreational boaters and 0.04% for commercial vessel operators.
- Harbors & Navigation Code §655(f): Applies to accidents involving injury or death-leading to felony charges and possible imprisonment.
These laws cover all motorized boats, sailboats under power, jet skis, and other personal watercraft. Even if you're anchored but have "operational control" of the boat, you can be charged with a BUI in certain situations.
Penalties for Boating Under the Influence in California
The penalties for a BUI conviction depend on prior offenses and whether there were injuries involved:
First-Offense BUI (Misdemeanor)
- Up to 6 months in county jail
- Fines up to $1,000

Defending Against a Boating Under the Influence Charge
A skilled California DUI lawyer can make a significant difference in the outcome of your case. At Walia Law Firm, we analyze every aspect of your arrest, including:
- Unlawful stop or boarding by law enforcement
- Improper BAC testing or faulty breathalyzer results
- Environmental factors that mimic impairment (sun, heat, motion, dehydration)
- Lack of probable cause or insufficient evidence
Our BUI defense attorneys in the Bay Area are experienced in challenging the prosecution's evidence and negotiating for dismissal, reduction of charges, or alternative sentencing options.
Common BUI Defense Strategies
Our experienced attorneys employ various defense strategies specific to boating cases:
- Challenging the initial boarding or stop as unlawful
- Questioning field sobriety test validity on a moving vessel
- Examining environmental factors affecting balance and coordination
- Investigating breathalyzer calibration and maintenance records
- Analyzing blood test chain of custody procedures
- Demonstrating medical conditions that mimic intoxication
- Challenging officer training and certification for marine enforcement
BUI and Driver's License Consequences
Although boating and driving are separate activities, a BUI arrest involving alcohol can trigger California DMV action. The DMV may suspend your driver's license under certain conditions, particularly if you hold a commercial driver's license (CDL) or if your BUI involved injuries or prior DUI convictions.
Our truck driver DUI attorneys in the Bay Area work to protect your driving privileges, employment, and clean record, coordinating with the license suspension team and CDL defense strategies.
Impact on Commercial Drivers
Commercial drivers face particularly severe consequences from BUI convictions:
- Potential CDL suspension even for non-commercial vessel operation
- Employer notification and possible termination
- Difficulty obtaining future commercial driving positions
- Enhanced penalties for any subsequent DUI or BUI charges
Environmental Factors in BUI Cases
Boating environments present unique challenges that can affect BUI investigations and prosecutions:
- Sun exposure and dehydration can mimic intoxication symptoms
- Boat motion affects balance and coordination naturally
- Engine noise can interfere with communication and testing
- Weather conditions may impact field sobriety test reliability
- Time delays in reaching shore for proper testing
