Boat and Yacht Insurance: Beyond Basic Auto — What It Covers on the Water
By the PolicyZen Team · Updated March 2026 · 8 min read
Many boat owners assume their homeowners insurance covers their vessel. Some have minimal coverage — typically up to $1,000–$2,500 for small boats under 25 horsepower. Anything larger, more valuable, or used regularly requires a dedicated marine insurance policy. Auto insurance provides no coverage on the water whatsoever.
Boat insurance (for smaller recreational boats) and yacht insurance (for vessels generally over 26 feet or higher value) are specialized marine policies covering the hull, liability, and related exposures on the water. They work similarly to auto insurance but with marine-specific perils: sinking, storm surge, collision with underwater objects, and liability to other boaters.
What Boat Insurance Covers
- Hull coverage (physical damage): Damage to the boat, motor, and permanently attached equipment from collision, sinking, fire, theft, storm damage, and vandalism. Can be ACV or agreed value (see below).
- Liability: Bodily injury and property damage to others caused by your boat. Critical if you injure another boater or swimmer, or damage another vessel.
- Medical payments: Medical expenses for people injured on your boat regardless of fault
- Uninsured watercraft: Coverage if an uninsured boater injures you
- Towing and assistance: Emergency on-water towing (similar to roadside assistance)
- Personal effects: Fishing equipment, water sports gear, personal items on board
- Fuel spill liability: Costs of cleaning up an accidental fuel spill
- Trailer: Coverage for the boat trailer (may be covered by auto policy when on a road)
ACV vs. Agreed Value — Critical for Boats
This matters more for boats than almost any other insurance. ACV pays the depreciated market value at time of loss — for a 15-year-old boat, this can be far less than the cost of repairs. Agreed value pays the stated value you and the insurer agreed to at policy inception, with no depreciation — you get back what you insured it for. For boats worth $20,000+, the difference between ACV and agreed value coverage is substantial.
Navigation territory limits are strictly enforced. Most boat policies specify where you're allowed to operate the vessel — coastal waters within a certain distance of shore, specific regions, or freshwater only. Operating outside the agreed navigation territory can result in a complete coverage denial for any claim that occurs outside that area. Know your policy's navigation limits before venturing beyond them.
Lay-Up Periods and Seasonal Discounts
Many boat policies include a "lay-up period" — typically winter months when the boat is stored. During lay-up, navigation coverage is suspended (you can't make a coverage claim for on-water incidents) but physical damage coverage for fire, theft, or storm while stored continues. Lay-up periods reduce premiums. Some policies offer discounts for boats stored in a dry slip or hurricane-secure facility.
Frequently Asked Questions
Does homeowners insurance cover my boat?
Only minimally. Most homeowners policies cover very small boats — typically up to $1,000–$2,500 for boats under 25 horsepower. Anything larger, more valuable, or used regularly requires a dedicated marine insurance policy. Auto insurance provides no watercraft coverage whatsoever.
What is agreed value vs. ACV for boat insurance?
Actual cash value (ACV) pays the depreciated market value of your boat at the time of loss — for an older boat, this can be far less than repair costs. Agreed value pays the full stated value you agreed on at policy inception, with no depreciation deducted. For boats worth $20,000 or more, this distinction is critically important.
What is a navigation territory limit and why does it matter?
Most boat policies specify where you're allowed to operate your vessel — such as coastal waters within a certain distance of shore, specific regions, or freshwater only. Operating outside the agreed navigation territory can result in a complete coverage denial for any claim that occurs outside that boundary. Always know your policy's navigation limits before any trip.
What is a lay-up period on a boat policy?
A lay-up period is typically the winter months when the boat is stored and not in use. During lay-up, on-water navigation coverage is suspended, but physical damage coverage for fire, theft, or storm while the boat is stored continues. Lay-up periods reduce premiums and some policies offer additional discounts for boats stored in dry slips or hurricane-secure facilities.
What does boat insurance liability coverage protect against?
Boat liability covers bodily injury and property damage to others caused by your watercraft. This is critical if you injure another boater, swimmer, or water skier, or if you damage another vessel. Uninsured watercraft coverage is also available and protects you if an uninsured boater injures you.
