Understanding Liability for Boating Accidents Involving Drunk Drivers
Boating offers a great way to enjoy California’s coastline, lakes, and rivers. But when alcohol enters the picture, what should be a relaxing outing can quickly turn dangerous. Drunk driving isn’t just a problem on the road. It’s a serious issue on the water, too. When a boating accident involves alcohol, questions about legal responsibility follow closely behind.
California has clear laws about boating under the influence (BUI), and those laws carry serious consequences. At G. Aldrich Law, we serve California communities in Lakeport and Woodland Hills, including Lake County, Los Angeles County, Colusa County, Riverside County, and surrounding Northern and Southern California counties.

How California Defines Drunk Driving on the Water
Operating a boat under the influence of alcohol or drugs is illegal in California. Harbors and Navigation Code § 655 says it’s unlawful to operate any vessel while under the influence. A person is presumed to be under the influence if they have a blood alcohol concentration of 0.08% or higher and 0.04% for commercial operators, according to the California Legislature.
These rules apply to motorboats, sailboats, jet skis, and even non-motorized boats. A person can be arrested for drunk driving on a kayak if they're impaired and causing danger.
When a boating accident happens, alcohol often makes injuries worse and increases the likelihood of fatal outcomes. Impaired operators typically show delayed reaction times, reduced judgment, and poor coordination—factors that all contribute to crashes.
Who May Be Held Liable in a Boating Accident Involving Alcohol
Liability in boating accidents isn’t limited to the person operating the vessel. Multiple parties may share legal responsibility, depending on the circumstances.
Here’s a breakdown of who might be liable:
The operator: If the person driving the boat was drunk and caused the accident, they’re usually the primary liable party.
The boat owner: If someone allowed another person to operate their vessel while intoxicated or knowing they were likely to become intoxicated, the owner might also face legal consequences.
Event organizers or rental companies: If the boat was rented or used for a chartered trip, liability could extend to companies that failed to vet or monitor alcohol use on board.
Multiple boaters: If more than one boat was involved, and both had operators under the influence, shared liability might come into play.
Determining liability depends on several factors, including who had control of the vessel, whether they violated boating laws, and whether their behavior contributed directly to the accident.
Criminal vs. Civil Liability
A person caught drunk driving a boat may face both criminal charges and civil liability. These are separate processes, but they often overlap.
Criminal charges for BUI can lead to fines, jail time, mandatory boating safety courses, and even the suspension of boating privileges. If someone is injured or killed, the penalties become more severe.
Civil liability focuses on compensation. Victims can pursue financial damages for medical expenses, lost wages, pain and suffering, and property damage. A civil claim doesn’t require a conviction in criminal court, though evidence from a criminal case may support a civil lawsuit.
Proving Fault After a Boating Accident
After a boating accident, proving fault is critical to any legal claim. In cases involving alcohol, it’s often easier to establish negligence. However, the process still requires a detailed review of the facts.
To prove liability, the injured party must show:
The operator owed a duty of care to passengers and others on the water.
The operator breached that duty by being under the influence or acting recklessly.
That breach directly caused the injuries or damages suffered.
Evidence often plays a key role. This may include:
Police or Coast Guard reports
Witness statements
BAC test results
Photos or videos from the scene
Expert testimony from accident reconstruction specialists
In drunk driving cases, blood alcohol test results are often among the most persuasive pieces of evidence. Still, even if there’s no test result available, eyewitness accounts and the operator's behavior may help prove impairment.
How Comparative Fault Affects a Case
California follows a “pure comparative fault” rule. This means that more than one person can share legal responsibility for an accident, and compensation is reduced according to each person’s share of fault.
For example, if you were injured while riding in a boat with a drunk driver, but you knew they were drinking heavily and didn’t take steps to avoid the trip, a court may find you partly responsible. If a jury says you were 20% at fault and awarded $100,000, you'd receive $80,000.
The comparative fault doesn’t block you from recovering damages, but it may reduce what you receive. This rule applies to all personal injury claims in California, including those involving boats.
Insurance in Boating Accidents
Unlike cars, boats aren’t required to carry liability insurance in California. That can make recovery harder in drunk driving accidents. If the at-fault party has insurance, it might cover medical costs, property damage, and other losses. But many boaters go without coverage, and others carry only limited policies.
When insurance is available, it may come from:
Boat insurance policies
Homeowner’s insurance (if it includes boating coverage)
Commercial insurance (for charter or rental companies)
If there’s not enough coverage—or none at all—victims may have to sue the responsible party directly. That can involve attaching assets or negotiating a payment plan through the court.
What to Do After a Boating Accident Involving Drunk Driving
After an accident, it’s normal to feel disoriented. Still, the steps you take can affect your legal options later on. If you suspect alcohol was involved, gather as much information as possible.
Here are a few immediate steps to take:
Call emergency services and report the accident.
Get medical help, even if you don’t feel seriously hurt at first.
Take photos of injuries, the boat, and the surrounding area.
Ask for contact information from everyone involved, including witnesses.
Make a report to the Coast Guard or local harbor patrol.
Avoid making statements about who was at fault.
You should also reach out to a personal injury attorney with experience handling boating accidents. These cases involve both state boating laws and general principles of negligence, and they often require a close look at liability issues, alcohol use, and damages.
Wrongful Death Claims After Alcohol-Related Boating Accidents
Some boating accidents involving alcohol have tragic outcomes. In cases where someone is killed, surviving family members may bring a wrongful death claim. These claims are separate from criminal charges and focus on the impact the death has had on loved ones. In California, a wrongful death lawsuit may seek compensation for:
Funeral and burial costs
Loss of financial support
Loss of companionship and affection
Emotional suffering
Only certain people can file a wrongful death claim, including a spouse, children, or dependents of the deceased. These claims often rely heavily on evidence of negligence or impairment, especially when alcohol use is involved.
Penalties for Drunk Driving a Boat in California
California takes drunk driving seriously, whether it happens on land or water. The penalties for a BUI conviction can be significant, especially if someone is injured or killed.
Standard BUI penalties may include:
Fines up to $1,000
Jail time up to six months
Boating safety classes
Probation
If someone is hurt, the penalties rise sharply. A BUI causing injury can be charged as a misdemeanor or felony, depending on the case. Felony convictions can lead to years in prison, steep fines, and a lasting criminal record.
Repeat offenses also carry harsher penalties. Someone with a prior BUI or DUI conviction faces increased jail time and longer probation.
Alcohol Use and Increased Risk on the Water
Many people don’t realize that alcohol has a stronger effect on water than it does on land. Sun exposure, motion, heat, and dehydration all amplify the effects of alcohol. Even moderate drinking can lead to impaired judgment and slower reactions.
The U.S. Coast Guard reports that alcohol use is the leading factor in fatal boating accidents nationwide. That statistic holds in California, where high boating traffic and alcohol consumption mix often during weekends and holidays. Being on the water doesn’t excuse impaired behavior. Courts hold boaters to the same standard of care expected of drivers on the road.
Filing a Claim After a Drunk Driving Boating Accident
If you’ve been injured due to drunk driving on the water, you may have a valid personal injury claim. You’ll need to show that the other party was impaired, that their behavior caused the accident, and that you suffered losses as a result.
It’s important to act within California’s statute of limitations. In most personal injury cases, you have two years from the date of the accident to file a lawsuit. If a government entity was involved, that timeline may be even shorter.
An attorney can help you identify responsible parties, collect evidence, and organize a strong case. These steps are critical when alcohol is involved, as they affect not just liability but also the amount of compensation available.
