Overview
The real cost of boat ownership in California is the line nobody quotes: boats are assessed county personal property tax every year, typically around 1% of the boat's value - a $40,000 boat means roughly $400 a year to the county assessor, forever. Buyers also owe use tax at their district rate on the purchase. The calculator adds up all three layers.

California boat registration FAQ
How much does boat registration cost in California?
Original registration is $29 (bought in an even year) or $49 (odd year), then $20 every two years. All California vessel registrations share one cycle ending December 31 of odd-numbered years - that's why the original fee differs by purchase year.
Why did I get a county tax bill for my boat?
California assesses vessels as taxable personal property: about 1% of assessed value annually, billed by your county assessor (due August 31 in most counties). It's the biggest recurring cost of California boat ownership and completely separate from DMV registration.
Which boats don't need California registration?
Unmotorized kayaks, canoes, rowboats, and paddleboards of any size, plus sailboats 8 feet or under with no motor. Anything with a motor - including a kayak with a trolling motor - and any sailboat over 8 feet registers with the DMV.
Do I pay use tax on a used boat from a private seller?
Yes, at your district rate (7.25%–10.75%), collected by the DMV at transfer. Genuine gifts and qualifying family transfers are exempt with REG 256 - the same rules as vehicles. Documented (Coast-Guard-registered) vessels pay CDTFA directly instead.
What's the mussel fee sticker?
The Quagga/Zebra Mussel Prevention Fee - $16 at registration/renewal for most motorized boats used on fresh water. Ocean-only vessels can be exempt. It funds inspection stations at California lakes.
Does my boat trailer register separately?
Yes - trailers are vehicles under the Permanent Trailer Identification (PTI) program: a one-time $20 PTI fee with a $10 renewal only every 5 years, handled at the DMV separately from the vessel.
