Boat and watercraft insurance: the homeowners sub-limit is not enough

Homeowners policies typically extend a small amount of coverage to watercraft — often a boat under a certain length and horsepower, with a physical-damage sub-limit around $1,000-$1,500 and thin liability. That's fine for a canoe or a small dinghy. For a powerboat, a sailboat, a personal watercraft, or anything you'd be sad to lose, that sub-limit is a rounding error against the real exposure, and you need a dedicated boat policy.

What a real watercraft policy covers

• Physical damage to the hull, motor, and equipment — from collision, sinking, storms, fire, and theft.
• Liability: injuries to others or damage to other boats and docks, which on the water can be severe and is the coverage that protects your assets.
• Medical payments for you and your passengers.
• Uninsured boater coverage — many boaters carry no insurance at all.
• Wreck removal and fuel-spill liability: legally mandated cleanup costs after a sinking can be enormous and are excluded from basic coverage without this.

The details that decide claims

• Navigation limits: policies restrict where you're covered (a lake, coastal waters within X miles, specific regions). Cruise beyond them and you may be uninsured.
• Lay-up periods: off-season storage months when the boat isn't in use often carry reduced premiums — but keep coverage for fire and theft during storage.
• Named-operator and experience clauses: some policies limit coverage based on who's driving and their experience.
• Wreck removal and pollution: confirm these are included at adequate limits — they're the exposures that surprise owners after a sinking.

The bottom line

The scrap of watercraft coverage in a homeowners policy is meant for a dinghy, not a real boat. Anything with meaningful value or horsepower needs a dedicated policy with solid liability, uninsured-boater coverage, and wreck-removal and pollution protection. Choose agreed value to avoid a depreciation fight after a total loss, and read the navigation limits and lay-up terms so you're never surprised to be uninsured on the water.
