Utah requires liability insurance on most motorboats and on all personal watercraft. Minimums are $25,000 per person and $50,000 per accident for bodily injury, plus $15,000 for property damage. A $65,000 combined single limit also meets the rule. Engines under 50 horsepower and airboats are exempt. If you run a boat on Lake Powell, Bear Lake, Flaming Gorge, or Jordanelle, you need that coverage before you launch. A homeowners policy will not fill it.
The Utah liability insurance requirement
Under Utah law, every motorboat and every personal watercraft operating on Utah waters must carry liability insurance. Minimum limits are $25,000 per person and $50,000 per accident for bodily injury. The property damage minimum is $15,000. A combined $65,000 single limit also satisfies the requirement. Motorboats with engines under 50 horsepower and airboats are exempt. Proof of insurance must be carried on board whenever the boat is in operation.
The full rule is published by the Utah Division of Outdoor Recreation. Non-Utah residents who register their boat in another state get 90 days to comply if they operate regularly on Utah waters.
Here is the practical takeaway. If you buy a boat in Utah, you are not in the same “not required by law” situation that most other states are in. You need liability coverage before you launch.
What Utah homeowners policies actually cover
Even if Utah did not have a liability requirement, your homeowners policy would not fill the gap. Most HO-3 Utah homeowners policies cap physical damage coverage for watercraft around $1,000 to $1,500.
Liability extends only to smaller boats. That typically means outboards under 25 horsepower, inboards or inboard-outboards under 50 horsepower, or sailboats under a certain length. Anything larger or more powerful falls outside the policy. Auto covers the trailer while you tow. It does not cover the boat.
A real Utah recreational boat needs a standalone watercraft policy. The state actually requires it for most owners.
What a real Utah boat policy covers
A Utah watercraft policy typically includes hull coverage, liability at or above the state minimums, medical payments, and on-the-water towing. Uninsured boater coverage and personal effects are usually optional add-ons. The state minimums are exactly that. Minimums. They are not the right limits to stop at.
Liability limits beyond the state minimum. Utah requires $25,000 per person and $50,000 per accident. A single serious injury on Lake Powell can blow past those limits in a matter of hours. A helicopter evacuation to a St. George or Las Vegas trauma center is expensive on its own. Surgery and rehab add to that. Moving up to $300,000 or $500,000 typically costs less per year than people expect. A personal umbrella over the boat, auto, and home together is usually affordable too.
Fuel spill liability. If your boat sinks at Bullfrog, the cleanup is your problem. Same if your fuel line fails at the Wahweap dock. Federal and state law generally assign cleanup costs to the vessel owner. A meaningful spill runs into the tens of thousands of dollars. Ask your agent specifically about pollution and fuel spill coverage limits.
Trailering, storage, and the Utah season
Hull coverage on a boat policy typically follows the boat while you tow. Confirm with your agent. Storage losses are common in Utah, especially for boats that sit outdoors through the winter.
A lay-up discount for the months the boat is not in use is worth asking about. The Utah boating season is shorter than in Nevada, Arizona, or California. The discount can add up.
