Boat Insurance Cost Calculator
Boat insurance in the Lloyd's market typically costs 1% to 1.5% of the yacht's agreed value per year, so a $400,000 catamaran runs about $4,000 to $6,000 annually. Lloyd's has no standard price list: underwriters price each vessel individually. This calculator shows your honest range and the terms that will shape your final quote.

How this calculator works
The range is the real market band: 1% to 1.5% of agreed value per year, from the indications London Marine Insurance Services Ltd uses to place yacht cover at Lloyd's of London. Every term shown, from the 10% named-windstorm deductible to the hurricane-box coordinates, comes from the actual policy wording and proposal form.
- 1The premium range is your agreed hull value multiplied by the 1% to 1.5% market band. Nothing else moves the number, because at Lloyd's nothing else honestly can before an underwriter sees the risk.
- 2Your answers switch real policy terms on and off: the hurricane-box deductible, Croatia's doubled deductibles, charter endorsements, survey requirements. They never fake-adjust the price.
- 3The eligibility gates are the market's own: trimarans, ferro-cement hulls and cigarette boats are not written here, and we say so instead of collecting your email first.
- 4The questions in the quote step are the underwriter's questions, taken from the Lloyd's proposal form. Answering them up front is what makes a 48-hour quote possible.

Boat insurance calculator questions
How much is boat insurance per month?+
In the Lloyd's market, boat insurance typically costs 1% to 1.5% of agreed value per year. On a $250,000 yacht that is about $208 to $313 per month; on a $500,000 yacht about $417 to $625 per month. Most policies are billed annually, so monthly figures are a planning guide rather than an instalment plan.
Is this calculator an official quote?+
No. It is an honest indication built on the market band and real policy terms. Lloyd's underwriters price each vessel individually after seeing the proposal form, so the only real number is a quote, which the producer desk returns in about 48 hours.
Why is there no exact price for yacht insurance?+
Lloyd's of London has no standard rate card. Each yacht is priced by underwriters on its value, age, survey status, use, waters and the owner's record. Any calculator that shows one exact number is inventing it. The honest answer is the band: 1% to 1.5% of agreed value per year.
What deductibles should I expect?+
Standard hull deductibles run 1% to 5% of agreed value. Named-windstorm claims in the Caribbean hurricane box carry a 10% deductible and require a signed hurricane plan during the Atlantic hurricane season, June 1 to November 30. Croatian waters carry doubled deductibles per claim.
Which boats are not eligible?+
Trimarans, ferro-cement hulls and high-performance cigarette boats are not written in this market. Vessels over about 20 years old typically need an in-force survey. Cuba, Haiti and Venezuela are restricted waters under standard terms.
What is the average cost of boat insurance?+
Published US averages for small production boats run roughly $300 to $650 a year, and higher in hurricane-exposed states, but those figures are for actual-cash-value cover on mass-market craft. Agreed-value yachts placed at Lloyd's are priced differently: about 1% to 1.5% of the agreed value each year, so a $250,000 yacht runs roughly $2,500 to $3,750 before any windstorm, charter or age loadings.
How much is boat insurance in Florida?+
Florida boats cost more to insure because of named-windstorm exposure. Cover in the Caribbean and Atlantic hurricane box carries a 10% named-windstorm deductible and requires a signed hurricane plan during the Atlantic hurricane season, June 1 to November 30. Outside the box, or with the boat hauled out and declared, the same 1% to 1.5% agreed-value band applies.
Does this estimate include fuel, dockage and maintenance?+
No. This calculator estimates the insurance premium only. The total cost of owning a boat also includes mooring or dockage, fuel, winter storage, routine maintenance and depreciation, none of which this tool covers. It answers one question: what the insurance will cost.
What is the difference between agreed value and actual cash value?+
Agreed value pays the insured value written on your policy after a total loss, minus the deductible, with no deduction for depreciation. Actual cash value pays the market value at the time of loss, so it falls as the boat ages. Cover placed at Lloyd's through London Marine Insurance Services Ltd is written on an agreed-value basis, which is why the premium is a percentage of that agreed figure.
