Boat insurance has one term that matters more than any other: how the insurer values your boat at the time of a total loss. Get this wrong and a $40,000 boat can pay out as little as $18,000.
Agreed value vs. actual cash value
Actual Cash Value (ACV) deducts depreciation. A 12 year old fiberglass cruiser may have lost 60 percent of its book value. Agreed Value pays a number you and the insurer settled on at policy inception, with no depreciation. Agreed value costs roughly 10 to 20 percent more in premium and is worth every penny on any boat over $25,000.
Navigation limits and lay-up periods
Most policies restrict where you can operate (typically inland and coastal US waters within 75 to 200 miles offshore). Going beyond requires an extended navigation endorsement. A lay-up period during winter cuts premium by 20 to 40 percent in exchange for limited use, useful for northern climates.
Coverages most owners overlook
Fuel-spill liability (federal Oil Pollution Act exposure of up to $939,800 per incident). On-water towing (BoatUS and Sea Tow charge $250 to $500 per incident otherwise). Personal effects on the boat. Hurricane haul-out reimbursement in coastal states.
How to lower your premium without dropping coverage
Take a USCG-approved boating safety course (5 to 10 percent off). Add a tracking device on boats over 26 feet. Bundle with auto and home. Maintain a clean boating record. Increase the deductible from $250 to $1,000 (typically saves 10 to 20 percent).
