California Vessel Registration: The Essential Guide for Boaters and Water Enthusiasts

There’s something magical about being on the water in California—whether you’re zipping across Lake Tahoe, paddling in the Sacramento Delta, or cruising the Pacific coast. But before you launch your boat, jet ski, or other watercraft, there’s one thing you can’t skip: getting your vessel properly registered. California’s vessel registration laws are there for everyone’s safety, to protect property, and to help fund waterway improvements. Let’s break down what you really need to know, so you can spend less time on paperwork and more time soaking up the sun on the water.

Who Needs to Register a Vessel in California?

Not every floating object needs a state-issued sticker, but most boats and motorized watercraft do. According to the California Department of Motor Vehicles (DMV), you must register your vessel if it meets these criteria:

• Required: All motor-driven vessels (regardless of size or type), sailboats longer than 8 feet, personal watercraft (like Jet Skis or Sea-Doos), and houseboats operated or moored on California’s waterways.
• Not Required: Non-motorized sailboats under 8 feet, canoes, kayaks, rowboats, inflatable rafts (without a motor), lifeboats (used only for emergencies), and vessels only used in private lakes or ponds. U.S. Coast Guard documented vessels have a different process (explained below).
• Out-of-State Boats: Visiting vessels registered in another state may use California’s waters for up to 90 consecutive days without registering, but after that, California registration is required.

Why Register Your Boat? (Besides Avoiding a Ticket!)

Vessel registration isn’t just about compliance. It helps law enforcement identify stolen boats, protects your ownership rights, and funds vital improvements—think safety patrols, launch ramps, and environmental cleanup. Plus, if you ever plan to sell or transfer your boat, proper registration and title will make the process smoother.

How to Register Your Vessel in California: Step by Step

1. Gather Required Documents:
   • Proof of ownership (such as a bill of sale, Manufacturer’s Statement of Origin, out-of-state title, or transfer paperwork)
   • Hull Identification Number (HIN) for vessels manufactured after 1972 (if yours doesn’t have one, the DMV can help assign one)
   • Completed application form (REG 343, available on the California DMV website)
   • Payment for applicable registration fees
2. Submit Your Application:
   • You can apply in person at a DMV office or by mail. Some boat dealers can process registrations for new vessels at the point of sale.
3. Receive Your Certificate and Decals:
   • Once approved, you’ll get a Certificate of Number (registration card) and two registration decals. The certificate must be kept on board, and the decals go on each side of the bow.

Registration Fees in California (2024)

• Standard two-year vessel registration: $37
• CF Number (original application): $29
• Quagga/Zebra Mussel Infestation Prevention Fee (if vessel is used in “non-coastal” waters): $16
• Duplicate certificate or decals: $15
• Penalty fees may apply if you’re late renewing your registration

These fees may change, so always check the DMV website or call ahead for the latest rates.

Where and How to Display Your Registration Numbers and Decals

California requires you to properly display your vessel registration number (“CF” number) and decals:

• The CF number must be painted or affixed to each side of the forward half of the boat, in block letters at least three inches high, in a color that contrasts with the hull.
• The registration decal goes three inches behind the CF number on both sides.
• Numbers and decals should be clear and readable from a distance.

Failure to display them correctly can result in a ticket or a request to leave the water.

When and How Often to Renew

• Boat registration in California is good for two years. Expiration is on December 31st of every odd-numbered year (for example, 2025, 2027, etc.), regardless of when you registered.
• Renewal notices are mailed out by the DMV in advance, and you can renew online, by mail, or in person.
• If you miss the deadline, late fees apply—and you can’t operate the vessel until your new decals arrive.

Transfers, Sales, and Name/Address Changes

• If you buy a used boat, you must transfer registration within 15 days of purchase. The seller signs over the Certificate of Ownership (title), and you submit it to the DMV with the proper forms and fees.
• Notify the DMV within 10 days of changing your address or if you sell, junk, or otherwise dispose of your vessel.
• Always keep your paperwork and proof of registration up to date—especially if you’re planning to travel or sell the boat.

Special Cases: Documented Vessels

If your boat is federally documented with the U.S. Coast Guard (usually larger commercial or pleasure craft), you do not need a California CF number. But you must still pay the state’s registration fee and get a California “Certificate of Ownership” sticker to show you’ve paid your dues. The DMV and the Coast Guard both require proof of ownership and documentation.

Boats Used Only on Private Property

If your boat is operated exclusively on private, non-navigable waters (like a farm pond or a private lake), you do not need to register it with the state. The moment you take it onto public waters, however, registration is required.

Boat Titles in California

For most vessels, your proof of ownership is the California Certificate of Ownership (similar to a car title). If you buy a new boat from a dealer, they’ll usually handle the paperwork for you. When buying a used boat, always get the signed title from the seller and keep it in a safe place.

Boater Safety Card Requirement

While not technically part of registration, as of 2024, anyone under age 60 operating a motorized vessel in California must have a California Boater Card, which is proof you’ve passed a state-approved safety course. The requirement is being phased in by age, so check the latest rules at californiaboatercard.com.

Penalties for Not Registering Your Boat

Operating an unregistered (or expired) vessel on California waters can result in fines, citations, and even impoundment of your boat. Law enforcement routinely checks for valid registration and boater safety cards, especially at busy ramps and marinas.

What If You Lose Your Certificate or Decals?

Lost or damaged registration certificates or decals can be replaced by contacting the DMV and paying a small fee. Don’t wait—if you’re stopped on the water, you’re expected to have your paperwork and current stickers.

Boats Coming From Out of State

If you move to California or bring a boat for long-term use, you must register it within 120 days. Temporary permits are available if you’re waiting for paperwork or need time to get a hull identification number verified.

Selling or Buying a Boat in California

1. Complete a Bill of Sale: This document should include names and signatures of buyer and seller, vessel description (CF number, make, model, year, length), HIN, and sale price.
2. Transfer Registration: Buyer must submit paperwork to the DMV within 15 days, and seller should also file a Notice of Transfer and Release of Liability.
3. Outstanding Liens: Clear any loans or liens before completing the sale; the DMV may require lienholder sign-off.

Helpful Tips for a Smooth Registration

• Double-check all paperwork before submitting—errors or missing information can cause delays.
• Renew your registration early, especially before peak boating season, to avoid delays or expired decals.
• Always keep your certificate of number (registration card) on board.
• For unique cases (homemade or rebuilt boats, boats with missing HINs), visit the DMV or call for special instructions.
• Keep a copy of your bill of sale and title in a safe place for future reference.

Frequently Asked Questions (FAQs)

• Q: Do I need to register my kayak or paddleboard?
  A: Not if it’s non-motorized and under 8 feet (for sailboats). But the moment you add a motor—even an electric one—registration is required.
• Q: My boat is only used on a private lake. Do I need to register?
  A: No, unless you plan to use it on public waters.
• Q: How long does it take to get my registration?
  A: In-person DMV visits can be same-day. Mail-in applications may take a few weeks, so plan ahead, especially before busy boating weekends.
• Q: Can I renew online?
  A: Yes. The DMV offers online renewal for most vessel registrations. Have your renewal notice and payment ready.
