Updated November 8, 2026. This article was written in July 2023, after the Operation Dry Water weekend of July 1 to 3, and reviewed as of this update. It is general information, not legal advice.
Where the water meets the bar
California has thousands of miles of coastline, dozens of large reservoirs, and busy rivers and deltas. Along them are marinas with bars, lakeside restaurants with docks, harbor-front cafes, and stores that sell ice, bait, and beer to boaters heading out for the day. For these businesses, summer is peak season, and so is the risk that a guest who has been drinking will take the helm of a boat.
This guide is for waterfront licensees: restaurants and bars with docks or slips, marina stores, and businesses that cater to boaters. It explains California’s boating under the influence law, what the 2023 Operation Dry Water campaign highlighted, and how staff can help keep the water as safe as the road.
What Operation Dry Water showed in 2023
On June 30, 2023, California State Parks’ Division of Boating and Waterways (DBW) reminded boaters to avoid alcohol over the Fourth of July weekend. DBW said law enforcement agencies nationwide would intensify their efforts July 1 to 3 as part of Operation Dry Water, and that more than 44 law enforcement entities in California would increase patrols or carry out boating under the influence (BUI) checkpoints.
DBW explained that Operation Dry Water was launched in 2009 by the National Association of State Boating Law Administrators in partnership with the U.S. Coast Guard. Citing Coast Guard 2022 recreational boating statistics, DBW said alcohol use is the leading known contributing factor in fatal boating accidents, and that where the primary cause was known, it was listed as the leading factor in 16 percent of deaths.
“Spending time in the outdoors is good for our mental, physical, and social health, but consuming alcohol and/or drugs can easily make these outdoor experiences dangerous,” said DBW Deputy Director Ramona Fernandez. “Boat Sober, Boat Safe, Stay Alive.”
The U.S. Coast Guard also announced increased safety patrols in California for the weekend in support of the campaign, noting that the 2022 Operation Dry Water effort resulted in 794 BUI arrests nationwide.
California’s BUI law in brief
According to DBW, in California it is against the law to operate a boat or water ski with a blood alcohol concentration of 0.08 percent or more, and officers may arrest boaters below that level if conditions are unsafe. DBW said BUI convictions can bring up to six months in jail and fines of up to $1,000, that two convictions within seven years can add a jail term of up to a year, and that impaired operators may have their voyage terminated and their vessel impounded. The law is found in Harbors and Navigation Code section 655.
For a licensee, the ABC Act rules still apply as they would anywhere: Business and Professions Code section 25602 prohibits serving an obviously intoxicated person, and section 25658 prohibits furnishing alcohol to anyone under 21.
Why the water changes the picture
Alcohol affects boaters in ways that are easy to underestimate:
- Sun, wind, and motion. Hours on the water can leave people tired and dehydrated, which can amplify the effects of alcohol.
- Passengers at risk too. Falls overboard and swimming accidents involve passengers as well as operators.
- Late departures. Guests who arrive by boat for lunch and stay into the evening may leave in fading light, with more traffic on the water.
- Two trips home. Many boaters drive a car and trailer home after leaving the water, adding a road trip to the risk.
For dockside restaurants and bars
Know who arrived by boat
When a group arrives at the dock, hosts can note it and ask, casually, who is operating the boat. That simple question lets servers treat the operator like a designated driver.
Treat the operator like a driver
Offer the boat operator nonalcoholic drinks, perhaps at no charge, and watch that they are not sharing drinks with the group. If the operator is drinking, staff should pace service and be ready to step in.
Watch the time
Afternoon arrivals who plan to leave before dark may linger. Remind groups of sunset times and encourage them to start back while there is light.
Step in before they cast off
If an obviously impaired guest heads for the dock to operate a boat, a manager should step in politely, suggest waiting, offer food and water, and help arrange alternatives such as a sober operator, a water taxi where available, or leaving the boat at the dock. If the guest insists, follow your policy on contacting harbor patrol or local law enforcement.
For marina stores and bait shops
- Check ID for every customer who appears under the store’s threshold, including young boaters buying for a group.
- Refuse sales to customers who appear obviously intoxicated, even if they say someone else is driving the boat.
- Watch for adults buying for minors waiting on a boat or at the dock.
- Stock water, sunscreen, and nonalcoholic drinks prominently.
Minors on the water
Lake and river days often include teenagers and young adults. Groups may pool money for drinks or ask an older friend to buy. Staff should check ID for anyone who appears under the house threshold and will be drinking, and should not hand alcohol to a group without knowing everyone’s age. For more on spotting borrowed or fake IDs, see Spring Break ID Checks.
Staff training for waterfront venues
A short seasonal briefing can cover:
- The 0.08 percent BUI limit and the fact that officers can arrest below it.
- How to identify the boat operator in a group.
- House policy on serving boat operators.
- Heat and dehydration warning signs.
- Who to call if an impaired guest tries to operate a boat.
All on-sale servers and managers also need Responsible Beverage Service (RBS) certification, required since July 1, 2022 and described on ABC’s RBS program page. Seasonal staff have 60 days from their first day; see California’s 60-Day RBS Rule for New Hires.
Working with harbor patrol and law enforcement
Harbor patrols, sheriff’s marine units, and the Coast Guard are part of the waterfront community. A good relationship helps when a problem arises. Know who patrols your waters, keep their contact numbers posted for staff, and invite them to share safety materials at the dock or the register. Many agencies take part in Operation Dry Water each year and welcome help spreading the message.
Food, water, and shade
Food slows the absorption of alcohol, and water helps guests stay hydrated after hours in the sun. Dockside venues can keep water free and visible, offer shade at every table, and promote food to groups arriving by boat. A guest who has eaten and had water is less likely to be impaired when it is time to leave.
Keeping records
Record refusals, interventions with boat operators, and any calls to harbor patrol in an incident log. A record shows that staff acted responsibly and helps managers spot patterns, such as busy afternoons when groups stay too long. ABC’s model house policies include a sample incident log.
Boat rentals and charters
Some waterfront businesses also rent boats or work closely with charter operators. Where a business both serves alcohol and rents boats, the two operations need to talk to each other. A guest who has been drinking at the bar should not be handed the keys to a rental boat. Rental staff can ask who will operate the boat, check that the operator appears sober, and decline the rental if not. Businesses that partner with charter companies can share their responsible service policies and ask how the charter handles passengers who are drinking.
Holiday weekends on the water
Holiday weekends are the busiest days on many lakes and harbors, and also when enforcement is most visible. The Fourth of July, Memorial Day, and Labor Day bring crowded launch ramps, packed docks, and long days in the sun. Staff should plan for heavier service, more groups arriving by boat, and more guests who have been drinking on the water before they arrive. For holiday staffing ideas, see our Fourth of July long weekend plan.
A scenario at the dock
A group of six ties up at a lakeside restaurant at 2 p.m. The host notes that they arrived by boat and asks who is driving. The server offers the operator a free iced tea and keeps an eye on her glass. By 5 p.m., the group has ordered several rounds, but the operator has stayed with nonalcoholic drinks. The server mentions that sunset is a few hours away, the group orders food, and they leave the dock in daylight with a sober operator. That is the outcome every waterfront venue is working toward.
Training for the off-season too
Waterfront business slows in winter, which makes it a good time to train. Schedule RBS certification and refreshers before the spring rush, update dock signage, and review last summer’s incident log. Staff who start the season prepared are more confident when the first busy holiday arrives.
A well-prepared crew also helps new hires learn the dock routines quickly.
Frequently asked questions
What is California’s BUI limit?
DBW says it is illegal to operate a boat or water ski with a blood alcohol concentration of 0.08 percent or more, and officers may arrest below that if conditions are unsafe.
Can we refuse service to a boat operator who seems impaired?
Yes. Section 25602 prohibits serving an obviously intoxicated person, and businesses may refuse service for safety.
When is Operation Dry Water?
It is held around the Fourth of July. In 2023 the national enforcement weekend ran July 1 to 3.
Signage and guest education
Simple signs at the dock and the host stand can reinforce the message: a reminder of the 0.08 percent BUI limit, a note that boat operators get free nonalcoholic drinks, and the phone number for local harbor patrol. Many agencies provide free Operation Dry Water materials, and DBW publishes boating safety information that venues can share with guests.
The bottom line
For waterfront businesses, the boat operator is the designated driver. Knowing who arrived by boat, treating the operator like a driver, watching the clock and the heat, and stepping in before an impaired guest casts off help keep California’s lakes, rivers, and harbors safe all summer.
