Boat Insurance for California
California boat insurance for boaters who know the water.
From Shasta Lake in the north to the Sacramento–San Joaquin Delta, Roamly works with carriers who understand how Californians actually boat.
California at a Glance
Requirement | Details |
|---|---|
Insurance requirement | Not required by state law for private recreational boats. Lenders usually require coverage on a financed boat, and many marinas ask for proof of liability coverage. |
Boater education | Since January 1, 2025, every operator of a motorized boat needs a California Boater Card, at any age. Operators 12 to 15 need a supervising adult aboard to run a boat over 15 hp. |
Boating under the influence | Operating a recreational boat at 0.08 BAC or higher is illegal. A first offense can bring up to $1,000 in fines and six months in jail, and it counts as a prior if you're later charged with DUI. |
Registration | Motorized boats register with the DMV, and registration renews by December 31 of every odd-numbered year. As of October 2026, original registration is $39 in an even-numbered year or $49 in an odd-numbered year, renewal is $20, and freshwater boats also need a mussel fee sticker. |
Requirements and regulations may change. Verify with the California Department of Insurance, the Division of Boating and Waterways, and the California DMV for the most current information.
What you need to know about Boat Insurance in California
California now requires a boater card for every motorized boat operator, taxes boats every year as personal property, and charges a separate invasive mussel fee for freshwater boating. Here's what actually shapes your policy.
California's Boat Insurance Rules
No California law requires insurance on a private recreational boat or personal watercraft. You can still be held responsible for damage or injuries you cause on the water, and marinas and lenders set their own coverage rules. We'll help you figure out what makes sense for how you boat.
Agreed Value for Your Boat
Your wake boat with the upgraded tower speakers, ballast system, and custom wrap isn't a stock boat. Roamly works with carriers who may value the work you've put in, not some database guess.
Electronics and Gear Coverage
Chartplotters, fish finders, tower speakers, wakeboards, and surf gear add up fast. Roamly works with carriers who may offer coverage options for marine electronics and the personal gear you bring aboard.
Coverage Lenders and Marinas Ask For
Financing a boat usually means your lender will require coverage for the boat itself, and many California marinas and dry-storage yards ask for proof of liability coverage before you can rent a slip or space. Roamly works with carriers who may help you meet those requirements, and we'll help you get the paperwork in order.
Protection Beyond Basics
Type | Details |
|---|---|
Mechanical Breakdown Coverage | Engines fail at the worst times — like miles up one of Shasta Lake's arms, far from the nearest marina. Through Roamly's carrier partners, coverage may be available to help with sudden mechanical breakdowns beyond warranty. |
Guest Medical Coverage | On a summer day at Lake Tahoe, friends take turns at the helm and on the tube. Roamly works with carriers who may offer medical payments options for guests hurt on your boat. |
Docking Mishaps | Crowded launch ramps and tight slips in the Delta lead to bumps and scrapes. Through Roamly's carrier partners, coverage may be available for damage from docking mishaps. |
Protect the Gear You Bring Aboard
A weekend in the Delta or a day on Shasta Lake means plenty of gear aboard — rods, wakeboards, coolers, and electronics on the dash. Many basic policies limit coverage for personal property, so check yours before your next trip. Roamly works with carriers who may offer coverage options for marine electronics and personal effects like fishing and water sports equipment, which may help you replace what's lost or damaged.
What California Actually Requires
California doesn't require insurance on a private recreational boat. What it does require: a California Boater Card for every motorized boat operator, registration with the DMV, and a life jacket on every child under 13 while a recreational boat is underway, unless the child is below deck or in an enclosed cabin. Freshwater boaters also need a mussel fee sticker, and that fee went up in 2026 under a 2025 law that widened the program to cover all invasive freshwater mussels. Going without coverage may be legal, but one collision can mean damage to another boat, a dock, or someone you hurt — and liability alone doesn't pay to fix or replace your own boat. We'll help you figure out what makes sense for your situation.
Real Value for Upgraded Boats
You set up your boat the way you wanted it: new electronics, a tower and speakers, a ballast upgrade, and a better trailer. Book value doesn't account for the upgrades you've added. Roamly works with carriers who offer Agreed Value coverage options — we'll help document your boat so it may be insured for an agreed amount that reflects your upgrades, which may help if you ever need to file a claim.

No. California law doesn't require insurance on a private recreational boat or personal watercraft. If you finance your boat, your lender will likely require coverage, and many marinas ask for proof of liability coverage before you can rent a slip. Even without a mandate, you can be held responsible for damage or injuries you cause on the water. Requirements may change — verify with the California Department of Insurance.
Yes, if you operate a motorized boat. Since January 1, 2025, the California Boater Card has been required for every motorized boat operator, regardless of age. As of October 2026, it's a one-time $10 card. Renters, out-of-state residents boating here for up to 60 days who meet their home state's boater education requirements, and operators directly supervised by an adult who holds the card are among the exemptions.
It depends on your boat's type, size, value, and horsepower, where you keep and use it — saltwater, the Delta, or a mountain lake — your boating experience, and the coverage you pick. Adding physical damage coverage, higher liability limits, or coverage for electronics and gear will change the price. Get a personalized quote to find out your rate.
Roamly is a brokerage — we work with carriers who may offer coverage options for marine electronics like fish finders and chartplotters, plus personal effects like fishing gear and water sports equipment. Limits and eligibility depend on the carrier, so it's worth asking before you buy. Coverage terms, conditions, and availability vary by state and policy.
Roamly works with carriers who offer Agreed Value coverage options. We may help document your boat and its upgrades up front so it can be insured for an agreed amount, not a depreciated book value. If it's totaled, the agreed value — less any deductible — is what the policy is built around. Coverage terms, conditions, and availability vary by state and policy.
California doesn't require either one. Liability pays for damage you cause to other people and their property — another boat, a dock, or someone hurt in a collision. "Full coverage" usually means adding physical damage coverage, which helps pay to repair or replace your own boat after a collision, theft, vandalism, or fire. If you're financing, your lender will likely require it.
Operating a recreational boat with a BAC of 0.08 or higher is illegal, and a first offense can bring up to $1,000 in fines, up to six months in jail, or both. California boaters are told they have the right to refuse a chemical test, but officers can seek a warrant for a blood sample. A boating conviction also counts as a prior if you're later charged with DUI. If a violation is on your record, Roamly works with carriers that may still be able to help you find coverage. Coverage terms, conditions, and availability vary by state and policy.
California bars credit-based pricing for auto insurance, but boat policies aren't covered by a specific credit-score law, so it's worth asking each carrier how it rates. Your boating experience, your boat, and where you keep it are also major rating factors, and how much each one counts varies by carrier.
Yes. California counties tax boats every year as personal property. If you own a boat on January 1, the county where it's kept sends a bill based on the local tax rate. It's separate from DMV registration and the mussel fee, so factor it into the yearly cost of owning a boat, along with insurance.
