What does boat, jet ski and pontoon insurance cover in California?
Boat and watercraft insurance covers hull physical damage to the boat, motor, and trailer, plus watercraft liability, medical payments, uninsured or underinsured boater coverage, on-water towing, and personal effects. A homeowners policy typically extends only very limited protection to watercraft, and marinas, lakes, or lenders often require proof of liability before you launch or berth.
Whether you keep a bowrider on a trailer, a sailboat in a slip, or a fishing boat you launch on the weekends, your boat needs coverage built for the water. We help California boaters put a policy in place that fits how and where you actually use your vessel.
Which coverages make up a boat policy?
Boat insurance policies may include the following core coverage components, depending on carrier and policy form:

Who needs it? Powerboat, sailboat, and personal watercraft owners across California, from the Delta and Lake Tahoe to coastal marinas. It may matter most if you tow to different lakes, keep your boat in a slip, or carry passengers often.
California does not generally require boat insurance statewide, but many marinas, lakes, and lenders do require proof of liability before you launch or berth. Your navigation area and lay-up period often affect how a policy is written.
How we help: we talk through how you use your vessel, where you keep it, and who rides along, then help you match coverage to those realities. If a marina or lender needs specific limits, we help you sort that out too.
Navigational limits define where the policy responds, and a boat kept beyond them needs the wider program reviewed alongside your wider personal program.
What does California require of a boat operator, and how does it touch the policy?
California does not set a liability insurance minimum for a recreational vessel the way it does for a car; marinas, lenders and yacht clubs set their own requirements by contract. What the state does require is an operator card. Under Harbors and Navigation Code section 678.11, since 1 January 2025 every person operating a motorized vessel on California waters must carry a California Boater Card issued by the Division of Boating and Waterways, a requirement phased in by age from 2018. A policy that requires the operator to comply with applicable law makes that card a condition worth confirming for every person who takes the helm, including guests. The other California specific is valuation. Boat policies are written on either an agreed value or an actual cash value basis, and a total loss on a depreciating hull settles very differently between the two; which basis a quote offers is the first term to read.
The Harbors and Navigation Code provisions cited here are as published by the California Legislative Counsel at the time of writing. The Legislature amends them from time to time, and that office publishes the current text.
Areas we serve
We write boat insurance across the San Fernando Valley, greater Los Angeles, the Conejo Valley and Ventura County, the Santa Clarita Valley, and the South Bay, from our office in Granada Hills. For local detail, see boat insurance in Marina del Rey and Redondo Beach. Boats kept on the mountain lakes are covered from our Big Bear and Lake Arrowhead pages. Or browse all the areas we serve in California.
A boat policy is separate from the auto policy that tows it, and a trailer on the road is covered by the towing vehicle’s liability, not the boat’s. Owners with more than one recreational vehicle can compare powersports and RV coverage. The wider program is on our personal insurance page.
Boat insurance in Southern California, explained
Do I need a California Boater Card, and will my insurer ask for it?
Since January 1, 2025, every operator of a motorized vessel on California waters needs one, regardless of age. Harbors and Navigation Code section 678.11 phased the requirement in by age from 2018 and closed it to everyone in 2025. It covers jet skis and any boat with an engine; sail-only and paddle craft are exempt, as are non-residents visiting for under 60 days and operators of rented vessels. The card is issued by the Division of Boating and Waterways after an approved safety exam, costs $10, and lasts a lifetime. Operating without one is an infraction, with a fine up to $100 for a first offense and a required course. No statute ties the card to insurance, and carriers do not require it. Many do give a discount for a completed safety course, so keep the certificate and ask.
Does homeowners insurance cover a boat, and what is the typical limit?
A little, for small craft only. Standard homeowners forms carry a watercraft sublimit that is commonly between $1,000 and $1,500 for the boat and its equipment as property. The liability section excludes owned inboard boats, outboards over a horsepower threshold, and sailboats over a stated length. A kayak, a dinghy or a small aluminum boat with a trolling motor may fit inside those limits. Anything with real horsepower, a trailer, or a slip at Marina del Rey or Long Beach needs its own policy for both the hull and the liability. The homeowners form also does little for the boat away from the house: theft from a storage yard, damage on the water and damage on the trailer are typically outside it. Read the watercraft paragraph in your homeowners policy once, and you will know whether you are relying on it by accident.
Agreed value or actual cash value: which hull coverage should I choose?
Agreed value, if the boat is worth insuring at all. Actual cash value pays replacement cost less depreciation at the time of loss, and on a boat depreciation is fast and arguable. Agreed value pays the figure you and the insurer set when the policy was written, in the event of a total loss, with the deductible taken off. What varies between policies is the partial loss: many forms apply depreciation to canvas, sails, outboards and batteries even on an agreed value hull, so read that clause. Two Southern California realities feed into the choice. Year-round salt water at Long Beach and Marina del Rey means corrosion and bottom-paint condition are underwriting questions, and an older hull will often need a marine survey before an insurer will agree a value. The survey is also your best evidence of the number when the claim comes.
Will my policy cover Catalina, the Channel Islands, or a run to Ensenada?
Only if the navigation area on the declarations says so, and that is a policy term, not a law. Many coastal territories reach Catalina and the northern Channel Islands; some are written in miles offshore, and the crossing to Avalon is roughly 22 nautical miles from the Long Beach breakwater. Mexico is an extension you confirm in writing before you leave. Mexican authorities require a temporary import permit on board, a tourist permit per person and proof of liability insurance. If there is fishing gear on the boat, everyone aboard needs a fishing license; the Mexican consulate’s boating guide lists them. Mexican marinas commonly expect a Mexican-issued liability policy, so ask us to arrange one rather than assuming the extension covers it. Coming home, federal law requires you to report your arrival to Customs and Border Protection immediately, and the penalty for not doing so starts at $5,000 with the boat subject to seizure.
Who pays for a fuel spill or raising a sunk boat?
You do, by statute, which is why the policy’s pollution and wreck removal limits matter. Federal law, 33 U.S.C. 2702, makes each responsible party for a vessel that discharges oil into navigable waters liable for removal costs and damages, and a recreational boat is a vessel with no size floor. The statutory limit for a small non-tank vessel is over $1 million, and it disappears if the spill involves gross negligence or a safety violation. On the California side, Harbors and Navigation Code section 525 makes abandoning a vessel an infraction with a fine up to $3,000 and lets the court order the owner to pay removal. Section 523 lets officers remove a vessel that creates a hazard and recover the cost. A $300,000 liability limit that has to absorb a fuel spill in the marina is not enough. Ask whether pollution and wreck removal sit inside the liability limit or in addition to it.
Does the marina require insurance, and do I have to name it?
Usually yes to both, and the terms are in the slip agreement. The City of Long Beach’s marina rules, for example, require liability coverage of at least $300,000 for a recreational vessel. The City and its officials must be carried as insureds under that policy, with an endorsement that coverage will not be canceled without prior written notice to the City. The Marina del Rey basins are operated by private lessees under County leases and each sets its own terms, typically proof of liability and an additional insured endorsement. Send us the slip agreement before you sign it; the certificate is a five-minute job when the policy was written with it in mind, and a renewal problem when it was not.
Does my auto policy cover the boat and trailer on the way to Castaic or Lake Havasu?
The auto policy generally extends liability to a trailer you are towing, and nothing else. Damage to the trailer and to the boat on it is not an auto claim unless the trailer is scheduled; it is the boat policy’s hull and trailer coverage. Two Vehicle Code rules apply on the road. Any passenger vehicle towing a trailer is limited to 55 miles an hour under section 22406. A trailer with a gross weight of 3,000 pounds or more must have brakes on at least two wheels under section 26302. Lake Havasu is in Arizona, where the California Boater Card is not required, and most policies’ territory includes inland waters of the continental United States; check the wording rather than assume it. And plan the return trip around the next section.
What are the mussel inspection rules at Castaic, Pyramid and other California lakes?
Strict, and not insurable. Fish and Game Code section 2301 prohibits possessing or transporting quagga or zebra mussels, lets officers stop, impound and quarantine a boat, and carries an administrative penalty up to $1,000. Every boat used in fresh water needs the biennial mussel fee sticker from the DMV, which funds the program but does not pay for individual inspections. Castaic Lake inspects every boat before launch and turns away any that is not completely dry for seven days. Quagga mussels were confirmed in Castaic in 2021 and have been in Lake Havasu and the lower Colorado since 2007, so a Havasu weekend means a decontamination before the next California lake. None of that cost is an insured loss. What is insured is the boat itself, on the trailer and on the water, and the liability for the people around it. Some boats we can place directly and quickly. Others need underwriting review or a wholesale market, and those take longer. Either way you know which applies before you decide. Start a boat quote or call the Granada Hills office.
