California Boat Registration Renewal: Fees and Deadline
Mo G
Last verified: September 28, 2026
California boat registration expires on December 31 of every odd-numbered year, so current CF stickers run through December 31, 2027. The biennial renewal fee is $20, and missing that midnight deadline adds a 50 percent penalty. Sticker Quicker renews California vessel registrations online and ships the documents by next-day FedEx, with no DMV visit and no mail-in wait.
Car registration teaches California boat owners a habit that is wrong on the water. Your truck renews on its own anniversary, a different month for every vehicle in the driveway. Your boat does not. Every undocumented vessel in the state renews on the same calendar square, and that square only comes around every other year. Miss it and the penalty is not a flat late fee. It is a percentage.
Which boats California actually requires you to register
The test is not size. It is power.
Definition: an undocumented vessel. A boat registered with the California DMV rather than documented with the U.S. Coast Guard. It carries a CF number and a registration sticker, the same way a car carries plates and a year sticker.
Per the California DMV Boat/Vessel Registration page (last modified August 7, 2026), you must register:
- Any vessel with a motor, no matter how big the motor is. A clamp-on trolling motor counts.
- Any sail-powered vessel over eight feet long.
- Dinghies and motorized houseboats.
This applies regardless of where you float it, private lakes included. You do not have to register canoes, rowboats, or anything moved by paddles or oars, sailboats under eight feet, sailboards, parasails, ships’ lifeboats, seaplanes, or floating structures tied to land. Commercial vessels over five net tons and 30 feet require U.S. Coast Guard documentation instead of DMV registration.
The practical trap: an 11-foot aluminum rowboat is exempt until the day you bolt a $90 electric motor to the transom. Then it is a registrable vessel, and every deadline below applies to it.
The renewal cycle: one date, every two years
California vessel registration is biennial and it is not anchored to your purchase date. Certificates of number expire December 31 of every odd-numbered year, and renewal must be completed on or before midnight of that date. That is the rule in VIRPM section 24.130, which cites Vehicle Code sections 9860, 9861 and 9863.
So the calendar for right now looks like this:
- Stickers issued for the current term are valid through December 31, 2027.
- DMV mails renewal billing notices roughly 60 days before expiration, which puts the 2027 notices around late October 2027.
- DMV says to renew “regardless of how often you use it.” A boat on a trailer in the side yard for two years still owes the renewal.
Two rules from the industry manual almost never appear on a consumer-facing page, and both cost people a trip:
- A REG 102 is not acceptable for vessels. The form that works for a car renewal does not work here.
- The vessel must be located in California to be renewed. Storing a boat out of state over the winter is not a detail DMV ignores.
If your registration lapsed long enough that a hold or a delinquent tax flag is sitting on the record, the renewal will not simply go through. We covered how that works on the vehicle side in California registration holds and what blocks your renewal.
What California vessel registration costs
These are the vessel line items from the DMV Registration Fees page, last modified June 30, 2026. This is the most recently revised fee schedule DMV publishes, and it is the one to work from.
| Transaction | Fee |
|---|---|
| Biennial renewal (due in odd-numbered years) | $20 |
| Renewal penalty, late | $10 |
| Original registration, vessel sold in an even-numbered year | $29 |
| Original registration, vessel sold in an odd-numbered year | $49 |
| Original registration penalty, even-numbered year | $10 |
| Original registration penalty, odd-numbered year | $25 |
| Transfer of ownership (except between dealers) | $15 |
| Transfer penalty, late | $8 |
| Replacement title or registration | $15 |
| Repossession | $15 |
One number in that table is worth reading twice. First registration costs $20 more in an odd-numbered year than in an even-numbered year, $49 against $29, because the odd-year original carries the boat into the next full biennial term. If you are shopping for a used boat in late 2027 and the deal can wait a few weeks, January 2028 is the cheaper side of the line.
The 50 percent penalty, and the $10 that hides it
Here is the gap. DMV’s consumer boat page gives you the December 31 deadline but never says what happens if you blow it. The fee chart gives you a $10 renewal penalty but never explains where $10 comes from. Only the industry manual, written for registration agents rather than boat owners, states the actual rule: miss midnight on December 31 of an odd-numbered year and a 50 percent penalty applies.
Put the two documents side by side and they are the same rule written twice. Fifty percent of the $20 biennial renewal is exactly the $10 penalty line on the fee chart. Neither page tells you that on its own.
Why it matters in practice: a percentage penalty scales. On a $20 renewal the damage is ten dollars and it feels like nothing. Stack it on a lapsed original registration, a transfer that also went late, and a delinquent county property tax flag, and the arithmetic stops being trivial. The cheap fix is never missing the date in the first place.
Skip the deadline math entirely. Sticker Quicker’s California boat and vessel registration service processes vessel renewals through a direct DMV connection, so the transaction posts in real time rather than sitting in a mail queue, and your documents go out by next-day FedEx. No field office, no appointment, no waiting to find out whether it landed before midnight.
The mussel sticker most boat owners forget
California charges a separate Quagga and Zebra Mussel Infestation Prevention fee on top of registration. Per the DMV Boat and Vessel Owners guide (last modified October 21, 2025), the essentials are:
- It applies to DMV-registered vessels used in California fresh water: the Delta, rivers, lakes, reservoirs and streams.
- Vessels used exclusively in marine waters are exempt.
- It was created by Assembly Bill 2443 and has been collected since 2013.
- You buy the sticker every two years and display it next to your registration sticker. The colors are matched, which is how enforcement spots a missing one from the dock.
- It can be purchased separately from registration through DMV’s Mussel Fee Sticker Request page.
We are deliberately not printing a dollar figure for the mussel fee here. The only DMV page carrying an amount was last revised in 2024, and publishing a two-year-old fee as current on a page people will act on is exactly the mistake worth avoiding. Confirm the amount at the time you file.
How to renew your California boat registration
- Find your CF number and your renewal notice. The CF number is painted or permanently affixed to both bow sides in vertical block characters more than three inches high, formatted CF 1234 AB or CF-1234-AB. If the notice never arrived, the registration is still due.
- Confirm the boat is physically in California. Per VIRPM 24.130 the vessel must be located in the state to be renewed.
- Clear anything sitting on the record first. Delinquent county property taxes and DMV holds will stop the transaction, and the industry manual cites Vehicle Code 9880 and 9900 on exactly that point.
- Pay the renewal and the mussel fee together. Both run on the same two-year clock, so handling them in one pass means one deadline instead of two.
- Choose your channel. DMV offers online, phone at 1-800-777-0133, mail to Vehicle Registration Operations in Sacramento, or a field office appointment. Or hand the whole file to a licensed DMV Business Partner and get the documents back next day.

Frequently asked questions
When does California boat registration expire?
California vessel registration expires on December 31 of every odd-numbered year. The current term runs through December 31, 2027. Renewal must be completed on or before midnight of the expiration date, and DMV mails renewal billing notices about 60 days beforehand, per VIRPM section 24.130.
How much is boat registration renewal in California?
The biennial vessel renewal fee is $20, per DMV’s Registration Fees page last modified June 30, 2026. A late renewal adds a $10 penalty. The separate Quagga and Zebra Mussel Prevention fee applies to vessels used in fresh water and is billed on the same two-year cycle.
What is the penalty for renewing a California boat registration late?
A 50 percent penalty applies to a vessel registration not renewed by midnight on December 31 of the odd-numbered expiration year. On the $20 biennial renewal that works out to the $10 renewal penalty shown on DMV’s fee chart. The rule appears in the industry manual rather than on DMV’s consumer boat page.
Do I have to register a boat I never take out?
Yes. DMV states that California boat and vessel registration must be renewed by December 31 of every odd-numbered year “regardless of how often you use it.” Storage on a trailer or at a dock does not suspend the requirement, and the vessel must be located in California to be renewed.
Does a small boat with a trolling motor need to be registered in California?
Yes. California requires registration for a vessel with a motor no matter how big the motor is, so a trolling motor makes an otherwise exempt rowboat registrable. Sail-powered vessels need registration once they exceed eight feet. Canoes, rowboats and other oar or paddle craft stay exempt.
