Do You Need a Boating License in California? Age and Exemptions

California does not issue a traditional boating license, but it does require a California Boater Card, and as of January 1, 2025 that requirement applies to everyone who operates a motorized vessel on state waters. The card is a lifetime credential you get by passing a state-approved boating safety exam and paying $10 plus a $1 service fee. So while the phrase “boating license in California” is common shorthand, the actual document you need is the California Boater Card.

Who Needs the Card

The requirement phased in by age group between 2018 and 2025. That phase-in is now complete. If you operate a motorized vessel on California waterways, you need the card, regardless of your age.¹

“Motorized vessel” covers more than powerboats. Personal watercraft like jet skis count. So do sailboats with auxiliary engines. Once the state issues the card, it doesn’t expire.²

Minimum Age to Operate

The card is one requirement. Age is another. To operate a vessel powered by a motor of 15 horsepower or more, including personal watercraft, you must be at least 16.³

Kids aged 12 to 15 can operate a vessel that powerful, but only under direct onboard supervision by someone 18 or older who holds a California Boater Card. Letting an unsupervised child under 16 run the boat is itself a violation.³

Boats with motors under 15 horsepower have no minimum operator age and no card requirement, though the usual safety rules on the water still apply.

Who Is Exempt

Several categories of operators don’t need the card:

Anyone operating a non-motorized vessel: kayaks, rowboats, and sailboats without engines.
Holders of a valid U.S. Coast Guard marine operator license, or a certificate issued under the International Convention on Standards of Training, Certification and Watchkeeping for Seafarers, for waters covered by that credential.⁴
Visitors from other U.S. states, for up to 60 days, as long as they meet their home state’s requirements.⁴
Visitors from other countries, for up to 90 days, under the same condition.⁴
People operating rented motorized vessels.⁵

The rental exemption is broader than people often assume. California law does not require renters to complete a safety briefing to qualify. Most reputable rental operations run through one anyway, and skipping it is a bad idea regardless of what the statute says.

How to Get Your California Boater Card

Pass an Approved Safety Course

You need to pass a boating safety exam through a course approved by both the California Division of Boating and Waterways and the National Association of State Boating Law Administrators (NASBLA).⁶ The Division publishes the approved provider list, and formats include online, classroom, and home study.

Prices vary. The BoatUS Foundation offers a free option; most paid online courses run $30 to $70. That cost is separate from the state’s card fee. Pick a provider, complete the material, pass the exam, and keep your certificate of completion or the certificate number the provider issues.

Submit the Application

Applications go through CaliforniaBoaterCard.com. Create an account, enter your personal information, and either upload proof of your completed course or provide your certificate number. You can also apply before taking the course; the portal issues an ApplicationID that you give to your course provider so they can submit your exam results directly.⁷

The state charges $10 plus a $1 service fee, payable by Visa, MasterCard, American Express, or Discover. Cash and checks aren’t accepted online.⁷ A mail-in application can go to the Division of Boating and Waterways in Sacramento if you prefer paper.

Receive Your Card

Once the Division approves everything, you’ll get a 90-day temporary California Boater Card by email. That temporary card lets you operate legally while the physical one is manufactured. The permanent card typically arrives by U.S. Mail within 30 days.⁷ Keep the temporary version on your phone or printed out until then. A replacement for a lost permanent card costs up to $10.

Penalties for Operating Without the Card

Operating a motorized vessel without a valid Boater Card is an infraction under Harbors and Navigation Code Section 678.15. Base fines climb with each offense:⁸

First offense: up to $100
Second offense: up to $250
Third or later offense: up to $500

Court fees and penalty assessments can push what you actually owe well above those numbers. One important exception: if you had a valid Boater Card at the time of the citation but weren’t carrying it, the fine is waived when you show proof.⁸ Keeping a photo of the card on your phone is worth the two seconds it takes.

Anyone convicted of the infraction must also complete and pass an approved boating safety course within seven months of conviction and submit proof to the court. For violators 18 or younger, the court can require parental consent before enrollment.⁸

Using Your Card Outside California

Because California’s approved courses are all NASBLA-certified, the credential travels well. More than 30 states honor NASBLA-approved course reciprocity for non-residents, including Florida, Texas, New York, and Washington.⁹ Each state sets its own terms, so check before your trip. Some accept any NASBLA certificate, others attach conditions, and a few don’t require boating education at all.

Going the other direction, visitors can operate in California for up to 60 days without a California Boater Card as long as they meet their home state’s boating education requirements. If your home state has no such requirement, you’re still covered during that 60-day window.⁴
