Boat Laws You May Not Know Exist in California

San Diego’s sparkling waters draw boaters year-round, from weekend sailors to seasoned anglers. But while the sunshine and ocean breeze invite relaxation, the laws governing California waterways aren’t always common knowledge. Some are less known, and failing to follow them can lead to fines, legal trouble, or dangerous situations on the water.

At Laureti & Associates, we’ve handled cases where a boating trip turned into a legal headache simply because the operator didn’t know the rules. Here are some California boating laws you might not expect, along with real-world examples that show why they matter.

Age and Operator Requirements

California sets clear age limits for operating certain watercraft, and breaking them can bring steep penalties.

Under 16 Rule – No one under 16 can operate a boat powered by more than 15 horsepower, except in limited supervised situations.

Boat-Ed Certification – A California Boater Card is required for operators, with age requirements increasing each year until it applies to everyone in 2025.

Example: A 15-year-old takes the family’s speedboat for a quick spin in Mission Bay while their parents lounge onshore. Not only is this illegal under California law, but if an accident happens, both the operator and parents could face serious legal consequences.

Boating Under the Influence (BUI)

Just like driving, boating under the influence of alcohol or drugs is a criminal offense in California.

Legal Limit – 0.08% blood alcohol concentration (BAC) for most operators.

Penalties – Possible fines, jail time, and loss of boating privileges.

Example: You’re anchored with friends near Coronado, enjoying drinks. A sudden storm prompts you to move to safer waters. Even without swerving or speeding, if you’re stopped and over the limit, you could be arrested for BUI and face the same penalties as a DUI.

Required Safety Equipment

Every vessel must carry certain safety equipment—failure to do so can lead to fines or worse if an accident occurs.

Life Jackets – One for each person aboard, and children under 13 must wear them while underway.

Fire Extinguishers – Required for most motorized boats.

Visual Distress Signals – Necessary for night operation in coastal waters.

Example: A small engine fire breaks out on your boat just outside the San Diego harbor. Without the required fire extinguisher, you can’t control the flames before they spread—endangering passengers and risking total loss of the vessel.

Local San Diego Considerations

San Diego’s waterways come with their own local rules and protected zones.

Speed Limits – Certain harbor areas have strict “no wake” or speed restrictions to protect docks, swimmers, and other vessels.

‍Environmental Protections – Anchoring or fishing in protected marine areas like the Cabrillo State Marine Reserve may be prohibited to preserve habitat.

If You’re Involved in a Boating Accident

Even the most careful operators can be involved in accidents. In California, serious boating accidents—those involving death, disappearance, injury requiring medical treatment, or significant property damage—must be reported to the Division of Boating and Waterways within a set time frame. If an accident happens:

Ensure Safety First – Check for injuries and get everyone to safety.

Report the Incident – Notify local authorities and follow state reporting rules.

Contact a San Diego boating accident lawyer – An attorney can help you deal with insurance, investigate the cause, and protect your rights.
