The checker

What is specific to Washington

Washington has one insurance duty on the water and it is easy to misread as broader than it is. Under RCW 88.04.025(4), the Charter Boat Safety Act, a charter boat carrying more than six passengers for hire must hold current and valid liability insurance and produce proof on demand. The statute states no amount. The six-passenger line is the boundary that matters: below it, the Act does not apply. RCW 88.12 separately licenses and insures whitewater river outfitters, which is a different activity again.

Nothing in state law for a private owner. Washington's Office of the Insurance Commissioner is the clearest official source anywhere on what happens when a financed boat's policy lapses: the lender force-places cover, which it describes as more expensive than buying coverage on your own.

Requirement two

What actually requires insurance in Washington

Three parties can require cover on a private boat. Only one of them is the state, and in most states it does not.

Physical damage, not just liability

Your lender will want physical damage cover, not just liability. Liability protects other people. The lender is protecting the asset it has a claim on, so it wants the hull itself insured.

Loss payee is a wording change

Your lender must be named as loss payee on the policy. This is a change to the policy schedule, not a phone call or an email. If the wording is not there, the requirement is not met, whatever cover you hold.

Let the policy lapse and the lender can buy cover for you and bill you. Washington's insurance regulator describes this force-placed insurance plainly: it is more expensive than buying coverage on your own, and it protects the lender rather than you.

Marina and slip agreements commonly set a liability limit somewhere between $300,000 and $1,000,000, with larger marinas at the higher end. That range is what we see in slip agreements rather than a statutory minimum, and no public primary source publishes it, so treat it as an expectation to check rather than a rule to rely on. Read your own agreement.

Three pieces of paperwork get conflated here, and none of them is insurance. State registration gives you a certificate of number and the numbers on your hull. Federal documentation with the Coast Guard is an alternative form of title for larger vessels. A boating safety certificate says the operator has passed a course. A state can require all three and still not require you to insure anything.

The sizing question

A state minimum is a floor, not a target

Utah statutory floor, per person: $25,000
Hawaii state harbour mooring permit: $300,000 to $500,000
Florida rental operator, per person, for a customer: $500,000
Large marina slip agreement, private owner: $1,000,000

The statutory floor is the smallest number in that list by an order of magnitude. It was written to catch the uninsured, not to reflect what a cruising yacht can actually cost someone.

What drives the limit you need is different from what drives the limit your state names. How many guests you carry. Whether wreck removal and pollution clean-up sit inside your liability limit or outside it, because on a grounding those two costs arrive together and they are not small. Where you cruise, and what the marinas and authorities there ask to see.

Questions

Frequently asked questions

Which states require boat insurance?+

Three: Arkansas, Utah and Hawaii. Arkansas and Utah require liability cover on motorboats over 50 horsepower and on all personal watercraft. Hawaii requires $100,000 of grounding removal-and-salvage cover on vessels 26 feet and over, which is not liability insurance. The other 47 states impose no insurance duty on a private recreational owner.

Is it illegal to not have insurance on your boat?+

In 47 states, no. In Utah, operating without owner's or operator's security is a class C misdemeanour under section 73-18c-302, and the Division can revoke the registration of a boat involved in an accident with no security in effect. In Arkansas, an owner whose uninsured boat is involved in an accident commits a Class A misdemeanour.

Do you need insurance on a boat to register it?+

In 47 states, no. Arkansas requires proof at registration and renewal. Utah requires a sworn written affirmation at registration and evidence carried aboard. Hawaii requires a declarations page at registration, renewal or transfer. Registration, Coast Guard documentation and a boating safety certificate are three separate things, and none of them is insurance.

What happens if you don't have boat insurance?+

Legally, in most states, nothing. Contractually, a lender can force-place cover at a higher price and a marina can refuse or end your slip agreement. Financially, wreck removal and pollution clean-up are the exposures that turn a grounding into a bill far larger than the boat was worth.

Does my homeowners policy cover my boat?+

Only up to a limited amount, and generally without liability cover. The Texas Department of Insurance states that homeowners policies do not provide liability coverage for a boat. Washington's insurance regulator says larger boats and personal watercraft are likely excluded from a homeowners policy for both property damage and liability.
