Boat Insurance in California

California does not legally require boat insurance to operate a watercraft on public waterways for personal use. However, if your boat is financed, your lender will almost certainly require coverage. Additionally, many marinas, harbors, and storage facilities will require proof of liability insurance before granting access or slip rental.

There are no state-mandated minimums for boat insurance in California. However, marina and lender requirements often include:

• Liability coverage to help cover injury or property damage to others
• Hull coverage for physical damage to your vessel

While these aren't required by the state, skipping coverage can expose you to out-of-pocket costs in the event of an accident or loss.

Boat insurance premiums in California vary depending on the type of boat, where it's used, and how it's stored. Here are average ranges:

• Small boats (under 26 feet): $200–$400 annually for basic coverage
• Larger vessels or yachts: $500–$1,500+ annually, depending on value and usage

Expect higher premiums in coastal regions like San Diego or the Bay Area, especially if you store your vessel in a marina or use it year-round.

There are several ways to reduce your premium:

• Increase your deductible to lower monthly or annual costs
• Complete a California-approved boating safety course for a potential discount
• Store your boat securely—in a dry dock, gated facility, or private garage
• Limit high-risk usage such as ocean racing or chartering, which are often not included within coverage

All motorized vessels and sailboats over 8 feet in length must be registered with the California DMV. You’ll receive registration decals and a certificate that must be carried while on the water.

To register, you’ll need proof of ownership, a completed application, payment of fees, and a hull identification number (HIN).
