Boat insurance in California for boats, yachts and jet skis.
Boat insurance in California for boats, yachts and personal watercraft: liability on the water, physical damage on agreed value, trailer coverage and the limits marinas and lenders ask for, with the same placement for boat owners in every other state.
Quick answer Boat insurance in California works as a watercraft policy that covers the boat, its motor and equipment, plus your liability to passengers and others on the water, matched to what marinas and lenders require.
- No California statute requires liability insurance on a recreational boat, and the DMV registration packet does not ask for it.
- Most marinas and yacht clubs ask for proof of boat liability coverage, often with the marina named as an additional insured, before they give the owner a slip.
- Agreed value on a boat policy is a value set at the start of the policy and used for a covered total loss, instead of a depreciated value.
- Some boat policies confine coverage to named waters, and a loss outside that navigational territory can void coverage for the loss.
- Homeowners policies often give little or no coverage for boats, especially larger or faster ones, and liability on the water may be excluded.

Your home policy likely isn’t enough
Homeowners policies often give little or no coverage for boats, especially larger or faster ones, and liability on the water may be excluded.
A watercraft policy covers the boat, its equipment and your liability to passengers and others.
- Physical damageThe hull, motor and equipment, on agreed value or actual cash value.
- LiabilityInjuries and damage you cause to others on the water.
- Medical paymentsInjuries to people aboard your boat.
- Trailer and towingOptions for the trailer and on-water towing.
What underwriters will ask
Having these ready means I can go to market on the first call. The quote form asks for the same things, and anything you don’t know yet can wait.
- Boat: year, make, length, hull material and HIN.
- Engine: type and horsepower.
- Value: purchase price or survey.
- Use: navigation area and season.
- Storage: marina, dry storage or trailer.
- Operators: who drives and their boating experience.
California boating rules that decide how a boat claim goes
The California rules behind the checklist above, from the DMV and the Division of Boating and Waterways (DBW):
- Registration. Any vessel with a motor and any sail-powered vessel over eight feet must be registered with DMV; canoes, rowboats and other paddle craft are exempt. The CF number goes on each side of the bow in plain block characters more than three inches high, and registration renews by December 31 of every odd-numbered year. A Coast Guard-documented vessel is not registered with DMV; give me the documentation number instead.
- Operator card. Since January 1, 2025, every operator of a motorized vessel on California waters, regardless of age, must carry a California Boater Card, a lifetime card issued by DBW for a $10 fee. Exempt: rental operators, anyone supervised aboard by a cardholder 18 or older, out-of-state visitors under 60 days, foreign visitors under 90 days, and certain commercial and Coast Guard-credentialed operators.
- Ages. No one under 16 may operate a boat with a motor over 15 horsepower, except a sailboat up to 30 feet or a dinghy run between a moored boat and shore; 12-to-15-year-olds may with an adult 18 or older aboard.
- Alcohol. Operating any vessel, water skis or similar device at 0.08 percent blood alcohol or more is illegal, and 0.05 to 0.08 can be used with other evidence. Disclose a conviction on the application.
- Accident reports. State law requires a written report to DBW after any accident involving a death, a disappearance, an injury beyond first aid, damage to a vessel or other property over $500, or the complete loss of a vessel: within 48 hours for a death within 24 hours, a disappearance or an injury, otherwise within 10 days. File even when you will not claim.
What a watercraft policy excludes, and the three conditions that decide a claim
Three policy conditions decide most disputed boat claims.
- Navigational limits. Some policies carry a navigational waters limitation that confines coverage to named areas, and a loss outside that territory can void coverage for the loss. Policies written on this coast often end at the border or at a stated distance offshore, so a run to Ensenada needs the clause read first (the San Diego page covers that run).
- Lay-up period. A dated stretch when the boat is declared out of use and coverage is suspended on the promise that it stays put. Match the dates to real use on Tahoe, the Delta and inland lakes; one warm weekend inside the lay-up is operating outside the policy.
- Operators and settlement method. Rating turns on the operators' driving records and experience on the water, so name every driver with age and Boater Card. Then read how a total loss pays: actual cash value, agreed value and replacement cost pay different amounts for the same damage, and the policy specifies which.
The physical-damage exclusions Maryland's insurance regulator lists as typical: wear and tear, marring, deterioration, rust, corrosion, mold, rot, latent defects, mechanical or electrical breakdown, freezing without reasonable winterizing, damage during repair or servicing, intentional acts, business pursuits, neglect, and any loss while the boat is in a race, speed run or other contest. If you race or charter, say so; both sit on that list unless the policy is written for them. For the liability limit, see how much to carry.
Fuel spill, wreck removal and salvage: the liability every boat owner already carries
Under the Oil Pollution Act, 33 U.S.C. §2702(a), each responsible party for a vessel from which oil is discharged, or which poses a substantial threat of a discharge, into navigable waters or adjoining shorelines is liable for the resulting removal costs and damages. The section carries no exemption for recreational boats, and a boat sinking at its slip with fuel aboard is a substantial threat of a discharge. Grounding was the third most frequent incident type in the Coast Guard's 2024 count, 394 of them, and a grounded hull is a salvage bill before it is a repair bill.
That is why wreck removal and towing appear among the additional coverages a boat owner's policy may provide, and why the Maryland regulator's shopping checklist asks each insurer, yes or no, about wreck removal. Hawaii makes the point by statute; California slip agreements often ask for fuel-spill and wreck-removal coverage by name. Before you bind, ask whether fuel-spill liability sits inside the liability limit or carries its own, and whether wreck removal is included or an option.
Boat insurance, answered
What does a personal watercraft (jet ski) policy cover?
California doesn’t require insurance on most boats or personal watercraft, but a jet ski policy covers physical damage, theft and liability if a rider injures someone or damages property. Many marinas, lenders and rental arrangements require it.
Does homeowners insurance cover my boat?
Often only small boats with low limits, and liability may be limited. Most boats need their own policy.
What do marinas and lenders require before a boat goes in?
Most marinas and yacht clubs ask for proof of liability coverage, often with the marina named as an additional insured, before they give you a slip. A lender wants physical damage coverage on the boat with itself listed as loss payee for the life of the loan. The exact limits are set by each marina or lender, so send me their requirements and I match the policy to them.
What is agreed value for boats?
A value set at the start of the policy that’s used for a covered total loss, instead of depreciated value.
Does it cover my trailer?
Many policies can include trailer coverage as an option.
Do I need a California Boater Card to operate my boat?
Yes. Since January 1, 2025 every operator of a motorized vessel on California waters, regardless of age, must carry one; it is a lifetime card issued by the Division of Boating and Waterways for a $10 fee. Rental operators, anyone supervised aboard by a cardholder 18 or older, out-of-state visitors under 60 days and certain commercial and Coast Guard-credentialed operators are among the exemptions.
Which states require boat insurance by law?
Arkansas (personal watercraft and motorboats over 50 horsepower, at least $50,000 per occurrence), Utah (motorboats and PWC, $25,000/$50,000 bodily injury and $15,000 property damage or $65,000 combined per accident; under 50 horsepower exempt) and Hawaii (vessels 26 feet and longer, at least $100,000 covering removal and salvage) are the three I have verified. Elsewhere the requirement usually comes from your marina or lender.
Do I have to report a boating accident in California?
Yes, when anyone dies, disappears or needs medical care beyond first aid, when damage to any vessel or property exceeds $500, or when a vessel is a complete loss. The written report goes to the Division of Boating and Waterways within 48 hours for a death within 24 hours, a disappearance or an injury, otherwise within 10 days.
Does boat insurance cover a fuel spill?
Boat policies differ: wreck removal and fuel-spill liability may be included, added by endorsement or left out, and the amount may sit inside the liability limit or stand alone. Federal law (33 U.S.C. §2702) makes the vessel's responsible party liable for removal costs and damages regardless, so ask before you bind.
Do you offer boat insurance outside California?
Yes. Clients across the country send the same quote form. California policies are placed directly; outside California the request is handled together with a partner agency in your state, and the shopping across carriers works the same way. Rules, minimums and markets differ by state — see insurance requirements by state.
