Boat Liability Insurance Cost

Quick answer: liability-only boat insurance may cost about $75-$500 per year for many recreational boats, but it does not repair or replace your own boat.

What Boat Liability Insurance Covers

Liability coverage is the part of the policy that helps if you damage someone else's boat, dock, property, or injure someone and are legally responsible. It is cheaper than full coverage because your own boat is usually not protected against collision, theft, storm, or sinking.

Boat Liability Insurance Cost FAQ

Is liability-only boat insurance enough? +

It may be enough for a low-value boat you can replace yourself, but it does not cover damage to your own boat in many losses.

What limits do marinas require? +

Many marinas require liability coverage, often with minimum limits. Requirements vary by facility.

Does liability cover passengers? +

Liability may respond if you are legally responsible for injury, but medical payments coverage is separate.

Is liability cheaper than full coverage? +

Usually yes because it does not insure the boat hull against many first-party losses.

Can I add umbrella coverage? +

Possibly. Ask whether your umbrella policy extends over boat liability and what underlying limits are required.

Does liability cover towing? +

No. On-water towing is usually separate or part of a broader package.
