Named Storm Deductible Calculator

A named storm deductible is a separate, higher deductible that applies only when a formally named storm causes the damage. It is a percentage of your yacht’s insured value, not a flat amount: multiply the insured value by the deductible percentage. A $500,000 yacht with a 5% named storm deductible carries a $25,000 deductible — you pay the first $25,000 of hurricane damage yourself.

How the named storm deductible is calculated

The formula is insured value × named storm deductible percentage. Unlike a flat standard deductible (often around $1,000–$5,000), it scales with the value of the boat, so the same 5% costs far more on a larger yacht.

Frequently asked questions

What is a named storm deductible?
A named storm deductible is a separate, higher deductible that applies only when damage is caused by a storm that has been formally named. It is set as a percentage of your yacht’s insured value rather than a flat dollar amount, so it scales with the value of the boat, and it replaces your standard deductible for that claim.
How is the named storm deductible calculated?
Multiply the insured value of the yacht by the named storm deductible percentage. A $500,000 yacht with a 5% named storm deductible carries a $25,000 deductible: you pay the first $25,000 of hurricane damage yourself, and the insurer pays the rest of the covered loss.
How does it differ from my standard deductible?
The standard deductible is usually a flat amount (often around $1,000 to $5,000) and applies to everyday losses. The named storm deductible is a percentage of insured value and applies only to named-storm damage, so it is typically many times larger: a $500,000 yacht at 5% is $25,000, against a $1,000 standard deductible.
Can I lower my named storm deductible?
Often yes. Many insurers will write a lower percentage (for example 2% instead of 5%) in exchange for a higher annual premium. Whether that trade is worth it depends on how many years of extra premium it takes to equal the deductible you would save on a single claim.
