If you own a sailboat over eight feet long or a boat/vessel with a motor (no matter the size), you must register it with DMV in order to legally operate it on California waterways.
To register your boat/vessel, you will need:
- A completed Application for Vessel Certificate of Number (BOAT 101) form.
- Proof of ownership, such as the original California Certificate of Ownership (title) or the out-of-state title (if it is currently registered in another state).
- If the original certificate is lost or damaged, complete an Application for Replacement or Transfer Title (REG 227) form to request a copy.
- Applicable fees.
- If you own a trailer for your boat/vessel, you need to register it separately.
You may also need:
- To complete an approved boating safety course and obtain a California Boater Card if you plan to operate a motorized vessel on a state waterway.
- Bill(s) of sale (if you bought your boat/vessel from a private party instead of a dealer).
- A Statement of Facts (REG 256) form, in case you do not have a copy of the bill of sale.
You can register your boat/vessel at any DMV field office, or mail your registration application and related documents to:
Department of Motor Vehicles
PO Box 942869
Sacramento, CA 94269-0001
You may also need to pay the Quagga and Zebra Mussel Infestation Fee and obtain a Mussel Fee sticker. Please see the Mussel Fee sticker request page for more information.
Frequently Asked Questions
Any boat or vessel that you can use to transport yourself on water, such as a:
- Sail-powered boat/vessel that is over eight feet long.
- Vessel/boat with a motor (no matter how big it is).
If you bought your boat/vessel from an out-of-state seller, or if you recently moved to California, you need to register your boat/vessel with DMV within 120 days of bringing it into the state.

- Canoes, rowboats, or any boats/vessels that use paddles or oars
- Sailboats shorter than eight feet long

Yes. Any boat/vessel that travels or is moored in California waterways, including private lakes, must be registered with DMV.
- A documented boat/vessel is registered with the U.S. Coast Guard and has a marine certificate. These boats/vessels do not have to be registered with DMV.
- An undocumented boat/vessel is registered with DMV and does not have a marine certificate from the U.S. Coast Guard.
If you buy a new boat/vessel, it is automatically considered undocumented, so you have to register the boat/vessel with DMV before you can put it in California waters.
Your boat/vessel will get a vessel registration number (beginning with CF before the numbers) when you register your boat/vessel with DMV.
You have to display your vessel registration number on your boat/vessel. Make sure it meets the following requirements.
Your Vessel Registration Number must:
- Be painted on or permanently attached to each side of your boat/vessel’s bow.
- Be written in plain, vertical block letters and numbers that are more than three inches high.
- Be properly arranged so you can read it from left to right.
- Contrast with the color of the background so that it is easy to see and read.
- Have spaces or hyphens that are the same size as letters other than “I” or numbers other than “1”.
- Example A: CF 1234 AB
- Example B: CF-1234-AB
In addition to your vessel registration number, you will also receive a registration sticker. You should attach it to the both sides of your boat/vessel, three inches apart from your vessel registration number.
Your registration sticker must be clearly visible at all times. Please do not place any numbers, letters, or devices near the registration sticker (other than your vessel registration number and Mussel Fee sticker (if required)).
If you boat in California fresh waters such as the Delta, rivers, lakes, reservoirs, and streams, you must purchase and display a Mussel Fee sticker next to your registration sticker. The Mussel Fee sticker matches the registration sticker by color and date.
You may purchase the Mussel Fee sticker online. The vessel registration/renewal and sticker transactions are separate. Once you receive your Mussel Fee stickers, place them on either side of the registration sticker as shown below.
Since 1972, all boats/vessels manufactured in the U.S. come with a Hull Identification Number (HIN).
The HIN must be:
- Painted on or permanently attached to your boat/vessel so that it cannot be changed or removed.
- Assigned and attached by manufacturers to commercially built boats/vessels.
- Assigned by DMV for homemade boats/vessels.
If your California Certificate of Ownership is lost, stolen, or damaged, you can submit a completed Application for Duplicate or Transfer of Title (REG 227) form.
If you lost your sticker, you can submit a completed Application for Replacement Plates, Stickers, Documents (REG 156) form to replace the lost certificates and/or stickers.
You can then mail the forms to DMV or visit a DMV field office in person.
You must renew your boat/vessel registration by December 31 of every odd-numbered year (for example, 2013, 2017, etc.), even if you do not use your boat/vessel.
To remind you that you need to renew your registration, DMV will mail you a renewal notice 60 days before your registration expires.
Visit our online registration page to see if your vessel is eligible to be renewed online.
You can also renew your registration by phone (automated system), mail, or by visiting a DMV field office in person.

If you renew your registration by mail, please return the bottom portion of your renewal notice in the envelope provided with a check, cashier’s check, or money order to cover your fees.
If you do not receive or lose the renewal notice, you may contact DMV and pay your fees.
When you buy a boat/vessel from another person, you should also get the California Certificate of Ownership from the person who sold it to you. That person should sign/endorse the certificate on line 1. If there is a lienholder, you need their signature on line 2.
Once you have the California Certificate of Ownership, write your name and address on the back. Then you can submit the certificate to DMV along with the transfer fee, use tax, and any renewal fees that might be due.
If the boat/vessel has a trailer, you need to get the trailer title. If you cannot get a copy of the title, you can complete a Permanent Trailer Identification (PTI) Certification and Application (REG 4017) form to transfer it into your name.
If you decide to sell your boat/vessel, you need to:
- Give the Certificate of Ownership to the person who buys it. Make sure you sign the certificate on the front.
- Contact the DMV within five days of the sale and fill out a Notice of Transfer and Release of Liability (REG 138) form.
You must provide the boat/vessel information (vessel registration number, HIN), the name and address of the buyer, and the sale date on the form.
- Submit the form online or by mail.
If the boat/vessel has a trailer, give the titling and/or registration documents to the buyer and submit a separate Notice of Release of Liability (REG 138) form.
Boats and vessels registered in California are included in property taxes by the county tax collector, depending on where the boat/vessel is stored or moored. DMV might deny registration renewal or transfer if the county tax collector tells DMV that you have not paid your personal property taxes.
Vessel registration becomes invalid when a boat/vessel is:
- Required to be documented by the U.S. Coast Guard.
- Transferred to a new owner.
- Destroyed or abandoned.
- No longer used primarily in California.
You must tell the DMV when a boat/vessel is:
- Moved to a different storage location.
- Documented through the U.S. Coast Guard.
- Destroyed, lost, or abandoned. Return the California Certificate of Ownership to DMV within 15 days.
