How do I transfer ownership of a used boat in California?

You will need to follow these steps:

1. Obtain a Bill of Sale: The first step in transferring ownership of a boat is to obtain a Bill of Sale. This is a legal document that proves the transfer of ownership from one person to another. The Bill of Sale should include the name and address of the buyer and seller, the make and model of the boat, the hull identification number (HIN), and the purchase price. 

2. Obtain a Transfer of Ownership Form: The California Department of Motor Vehicles (DMV) requires a Transfer of Ownership Form (Form REG 262) to be completed and signed by both the buyer and seller. You can download this form from the DMV website or pick up a copy from any DMV office.

3. Pay the Transfer Fee: The transfer fee for transferring ownership of a boat in California varies based on the value of the boat. You can check the current fees on the DMV website. The transfer fee must be paid at the time of transfer. 

4. Submit the Documents: The completed Transfer of Ownership Form, Bill of Sale, and transfer fee must be submitted to the DMV within 5 days of the transfer of ownership. You can submit the documents in person at a DMV office or by mail.

5. If you own a trailer for your boat/vessel, you need to register it separately.

Once the DMV processes your documents and transfer fee, they will issue a new registration and title for the boat in the name of the new owner.
