What Is a Fault Exclusion in Yacht Insurance?
Learn how fault exclusions work and what they mean for your yacht insurance claim.
Updated August 16, 2026
A fault exclusion in yacht insurance means that if you or someone on your boat causes the damage, your insurance might not pay for it. It’s like saying, “If you did it, you pay for it.” This is different from other types of insurance where the person at fault is always covered. In yacht insurance, if you’re found to be at fault in an accident, your claim could be denied or reduced based on the fault exclusion in your policy.
What Is a Fault Exclusion and Why Does It Matter?
A fault exclusion is a rule in your yacht insurance policy that says if you or someone on your boat is responsible for an accident or damage, the insurance company may not cover the cost. This is especially important in yacht insurance because many claims involve people, not just property. If you cause a collision or run aground, the insurance company might say, “You were at fault, so you pay.”
How Fault Exclusions Work in Yacht Claims
Fault exclusions are not about whether the damage is real or not. They’re about who caused it. If you’re found to be at fault in a claim, your insurance might not cover the full cost. This can happen in situations like:
- Colliding with another boat
- Running aground due to poor navigation
- Spilling fuel or oil into the water
- Having a guest injured due to your negligence
Each of these situations could trigger a fault exclusion, depending on your policy and the details of the incident.
How Fault Exclusions Affect Protection & Indemnity (P&I) Coverage
Protection & Indemnity (P&I) insurance is a special type of coverage that helps you pay for things like:
- Damage to other people’s property
- Injuries to guests or crew
- Salvage and wreck removal
- Pollution liability
But if you’re at fault, your P&I coverage might not pay for the full amount. For example, if you hit a dock and caused $100,000 in damage, and you were 100% at fault, your P&I coverage might not cover any of it. If you were 50% at fault, you might only get 50% of the claim paid by the insurance company.
How Fault Exclusions Work with Crew Liability
Crew liability is part of your insurance that covers injuries to your crew members. If a crew member gets hurt because of your fault, your insurance might not cover the full cost. For example, if a crew member falls overboard because you didn’t secure the deck properly, your insurance might say, “You were at fault, so you pay.”
How Fault Exclusions Work with Personal Effects Coverage
Some yacht insurance policies cover personal items like electronics, clothing, or jewelry that are on board. But if you or someone on your boat causes damage to those items, the insurance might not pay for it. For example, if you drop your phone in the water, your insurance might say, “You were at fault, so you pay.”
How Fault Exclusions Work with Pollution Liability
If your boat spills fuel or oil into the water, your insurance might not cover the cost if you’re at fault. For example, if you accidentally hit a rock and the fuel tank leaks, your insurance might say, “You were at fault, so you pay.” This is especially important in areas with strict environmental laws.
How Fault Exclusions Work with General Average
General average is a legal principle that says if you sacrifice part of your boat or cargo to save the rest, the cost is shared among all the people involved. But if you’re at fault for the situation, your insurance might not cover your share. For example, if you try to save your boat by jettisoning cargo and you were at fault for the accident, your insurance might say, “You were at fault, so you pay.”
How Fault Exclusions Work with Seaworthiness
Your boat must be seaworthy, which means it’s safe to sail. If your boat isn’t seaworthy and you cause an accident, your insurance might say, “You were at fault, so you pay.” For example, if your boat’s engine fails because you didn’t maintain it properly, your insurance might not cover the damage.
How Fault Exclusions Work with Lay-Up Warranty
If you lay up your boat (store it for a long time), you must follow certain rules to keep your insurance valid. If you don’t follow those rules and something happens, your insurance might say, “You were at fault, so you pay.” For example, if you leave your boat in the water without a lay-up warranty and it gets damaged, your insurance might not cover it.
How Fault Exclusions Work with Navigation Limits
Your insurance policy might say where you can and can’t sail. If you sail outside those limits and something happens, your insurance might say, “You were at fault, so you pay.” For example, if your policy says you can’t sail in the Caribbean and you do, and your boat is damaged, your insurance might not cover it.
How Fault Exclusions Work with Total Loss and Constructive Total Loss
If your boat is a total loss (completely destroyed) or a constructive total loss (too expensive to repair), your insurance might not cover it if you’re at fault. For example, if you hit a rock and the boat is a total loss, your insurance might say, “You were at fault, so you pay.”
How Fault Exclusions Work with Agreed Value vs Actual Cash Value
Agreed value is when you and your insurance company agree on the value of your boat. Actual cash value is the current value of your boat, which might be lower. If you’re at fault, your insurance might pay based on actual cash value, not agreed value. For example, if your boat is worth $500,000 agreed value but only $300,000 actual cash value, and you’re at fault, your insurance might only pay $300,000.

How to Avoid Fault Exclusions
The best way to avoid fault exclusions is to be careful and follow the rules. This includes:
- Keeping your boat seaworthy
- Following navigation limits
- Following lay-up warranties
- Being a responsible skipper
If you do these things, you’re less likely to be at fault in a claim, and your insurance is more likely to cover the cost.
What to Do If You’re in a Claim
If you’re in a claim and you think you might be at fault, don’t panic. Contact your insurance company as soon as possible. Be honest about what happened. If you were at fault, your insurance might not cover the full cost, but it’s better to be upfront than to try to hide it.
Final Takeaway
Always read your yacht insurance policy carefully. Understand what your fault exclusions are and how they might affect your claim. If you’re unsure, ask your insurance agent. The best way to protect your boat is to know your policy and follow the rules. If you do, you’ll be less likely to be at fault and more likely to get the coverage you need.
