How Much Does Boat Insurance Cost in Illinois?

Will Illinois require boat insurance starting in 2027?

Yes. Illinois passed Public Act 104-0651 in 2026, adding a new Section 5-24 to the Boat Registration and Safety Act (625 ILCS 45/5-24). Starting January 1, 2027, it will be unlawful to own or allow the operation of a motorboat over 50 horsepower, a motorboat longer than 21 feet, or a personal watercraft (including jet skis) in Illinois without liability insurance. The policy must come from an insurer licensed in Illinois and carry limits at least equal to the minimums already required for Illinois auto insurance under Section 7-203 of the Illinois Vehicle Code, which is 25/50/20 coverage.

This mirrors the liability requirement Illinois already has for snowmobiles under 625 ILCS 40/3-13. Boat and personal watercraft owners now join snowmobile riders as one of the few groups of recreational vehicle owners in Illinois with a legal insurance mandate, separate from anything a marina, lender, or homeowners association might already require.

How much does boat insurance cost in Illinois?

Less than most owners expect, and it is priced differently than auto insurance. Rather than a flat rate, boat insurers typically price a policy at roughly 1% to 5% of the boat's insured value per year, then adjust for horsepower, age, storage, and how the boat is used. On real premiums, insurers report states cluster into cost tiers, with national averages running from about $275 a year in lower-cost states up to roughly $870 a year in higher-cost states; the broad range most owners land in is $200 to $650 a year for liability plus physical damage coverage.

*Estimates only, based on the published 1% to 5% of insured value pricing rule and 2024-2025 average state premiums reported by national insurers and comparison sites. Most owners land toward the lower end of a given value tier. Your exact premium depends on the boat's age, horsepower, where you store and operate it, your boating experience and claims history, the coverage limits and deductibles you choose, and is confirmed by a licensed producer.

What happens if you operate without insurance once the law takes effect?

Once Public Act 104-0651 takes effect on January 1, 2027, operating or allowing the operation of a covered motorboat or personal watercraft without the required liability policy will be a petty offense, carrying a fine of more than $500 but not more than $1,000. A first-time offender who shows current coverage at their court date can instead pay a $100 fine with court supervision, and no conviction results if proof of insurance is shown at the time of the stop. You will also have to show proof of insurance on request to law enforcement or to anyone who claims you injured them or damaged their property while operating the boat.

Does homeowners or auto insurance cover your boat?

Usually only in a very limited way. A standard homeowners policy may offer a small amount of liability coverage for a small boat with limited horsepower, but most policies exclude larger or faster boats entirely and will not pay to repair or replace the boat itself without a specific endorsement. Your personal auto policy does not extend to a boat at all, even one you tow on a trailer.

That gap is the same one Illinois owners run into with other recreational vehicles. See our guides on jet ski and personal watercraft insurance cost, snowmobile insurance cost, and boat trailer insurance cost for how the same pattern plays out across other vehicles Illinois families own. A dedicated boat insurance policy closes the gap and, after January 1, 2027, is what the new law will require for larger boats and personal watercraft.

What does a boat insurance policy actually cover?

A boat policy carries liability coverage for injuries and property damage you cause to others while operating the boat, which is the piece the new Illinois law requires for covered vessels. Most owners add physical damage coverage, split into collision (damage from a crash or grounding) and comprehensive (theft, fire, sinking, and storm damage), plus uninsured boater coverage, towing and emergency assistance on the water, and medical payments for the boat's own occupants. Liability limits commonly range from $15,000 to $300,000, with typical deductibles of $250 for property damage, $500 for theft, and $1,000 for medical payments, though these vary by insurer and policy.

What affects the cost of boat insurance?

Insurers price a boat policy based on the boat's value, age, and horsepower, where you store it and how often you use it, whether you boat on inland lakes or larger open water, your boating experience and claims history, and the liability limits and deductibles you choose. Completing a boating safety course and bundling the policy with your home or auto coverage are the most common ways to lower the premium. Owners who also carry a personal umbrella policy should confirm the boat policy meets the umbrella's underlying-limit requirement, which is usually higher than the new law's 25/50/20 minimum.

Illinois's new boat and personal watercraft insurance requirement is Public Act 104-0651 (625 ILCS 45/5-24), published by the Illinois General Assembly.
