Do I need a California boater card to run a boat?

Yes, if your boat has an engine, at any age, unless an exemption covers you. To get the card, pass an approved course. The state's boating agency has a free one. Renting a boat is exempt, and so is running a boat under the direct supervision of an adult who holds a California boater card. Some visitors from other states are exempt too.

How to get it done

  1. Step 1. Check that the card covers you. It applies to anyone running a boat with an engine. Renting a boat is exempt, and so is running a boat under the direct supervision of an adult who holds a California boater card. A visitor who lives in another state is exempt for a stay of less than 60 days, if they meet their home state's boating rules. The state's FAQ lists the other exemptions.

  2. Step 2. Start with the free options. DBW, the state's boating agency, has its own course, the California Course for Safe Boating, and its course page says the course and exam are free. You can read the course online or download it, and you request the exam pack by email, then it is mailed to you. The state's list also shows a free online course, the BoatU.S. Online Boating Safety Course from BoatU.S. Foundation, with a cost of none. For any other online or classroom course, pick one from the state's list of approved courses. The course has to be on that list.

  3. Step 3. Take the course and pass its exam. Then apply, upload your certificate, and pay the card fee plus the service fee with a credit or debit card. You can also apply before the course: you get an application ID, give it to your course provider, and the provider sends it to DBW as proof. If the provider doesn't ask for it, or you didn't enter it on its site, email your certificate to DBW.

  4. Step 4. When DBW approves your application, your proof of the course and your payment, you print a temporary card that lasts 90 days. The permanent card follows by mail within 30 days.

Before you pay

Check that the course is on the state's approved list before you pay for it, or take a free one: DBW's home study course or the online BoatU.S. course on the state's list.

A card from another state doesn't stand in for the California card if you live in California.

DBW takes only credit or debit cards for the card fee. No cash, no checks.

The state adds a $1 service fee to the $10 card fee when you pay.

Finish within a year of applying. An application left open longer is canceled with no refund.

We haven't confirmed prices for paid courses, the minimum hours for classroom or home study courses, or whether a paid course charges extra for the certificate.

Questions

Is there a free course for the California boater card?

Yes. DBW's own California Course for Safe Boating and its exam are free. You can read the course online or download it, and you request the exam pack by email. DBW mails the certificate within two to four weeks if you pass. The state's list also shows a free online course, the BoatU.S. Online Boating Safety Course from BoatU.S. Foundation. With either one you still pay the card fee when you apply.

I live in California and hold a boater card from another state. Does it count?

Not on the water. California doesn't accept another state's card unless you live in another state and are only visiting. Take an approved California course and apply. The state's FAQ has the full rule.

I live in another state. Can I boat in California without the card?

Maybe, for a short stay. Residents of other states are exempt if they are in California for less than 60 days and meet their own state's boating requirements. Carry proof of your exemption.

Do I need the card on a lake that two states share?

Yes, if California is your primary home. A vacation home doesn't count as your primary home.

What happens if I'm stopped without the card?

A first conviction carries a fine, and the court also orders you to complete and pass an approved boating safety course. The FAQ gives the amounts.

Is there an age rule for running a boat?

There is a separate one. Nobody under 16 may run a boat with a motor of more than 15 horsepower. The exceptions are a sailboat no longer than 30 feet, and a dinghy used directly between a moored boat and the shore or between two moored boats.

What to do next

Pick your course from the state's approved list, or take a free one from DBW or BoatU.S. Pay the card fee when you apply.
