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).

The HIN must be:

- Assigned and attached by manufacturers to commercially built boats/vessels.
- Assigned by DMV for homemade boats/vessels.

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.

You must tell the DMV when a boat/vessel is:
