Formula Used
Risk Multiplier = Area × Usage × Material × Engine × Storage × Crew × Certification × Safety × Home Port × Marina Security × Age × Length × Claims × Deductible × Experience × Training × Survey × Refit × Navigation × Layup × Add-ons × Credits
Annual Total = (All coverages + Policy Fee) × (1 + Tax Rate)
How to Use This Calculator
- Enter insured value, length, and year built.
- Choose area, usage, and storage method.
- Set experience, survey age, and refit year.
- Adjust deductibles and core limits.
- Add towing, pollution, and crew medical if needed.
- Set navigation and layup months realistically.
- Press Calculate, then export results if desired.
Market premium ranges by insured value
For planning, many policies cluster between 0.7% and 2.5% of insured value per year, before taxes and fees. Newer coastal pleasure yachts often sit near the lower end, while older vessels, offshore routes, tropical navigation, and commercial use can push totals higher. This calculator starts from a 1.1% baseline and applies multipliers so you can compare scenarios consistently.
Risk multipliers that move the estimate most
The largest shifts typically come from cruising area, usage type, vessel age, and length. In the model, tropical navigation and global cruising apply stronger factors than inland routes, while charter exposure raises both hull and liability assumptions. Age bands step up after 10, 20, 30, and 40 years, and length adds incremental load above 50, 80, and 120 feet.
Deductible and exposure months as budget levers
Deductibles can reduce premiums when they meaningfully exceed a reference level of about 1% of insured value. The calculator also includes navigation months and optional layup months to represent reduced exposure when the yacht is inactive or stored. Use the deductible sensitivity chart to see how hull premium changes across a practical range without changing other inputs.
Coverage add-ons and why they matter
Optional protections can add noticeable cost even when hull premiums are stable. Towing and assistance limits increase convenience for minor incidents. Salvage and wreck removal may materially affect large-loss outcomes. Pollution liability, uninsured boater coverage, and crew medical limits become more relevant for higher-traffic waters or professional operations. Add-ons are modeled as separate components so you can see their contribution clearly.
Scenario planning and export workflow
To compare decisions, keep insured value constant and vary one driver at a time: area, usage, deductible, or add-ons. Save each run using the CSV export for quick spreadsheet comparisons, then use the PDF export for a clean record you can share internally. The goal is consistent budgeting: identify which choices create the largest premium swing and set limits that match your risk tolerance.
FAQs
Is this calculator an insurance quote?
No. It produces an illustrative estimate using simplified factors so you can compare scenarios. Final pricing depends on underwriting, inspection or survey results, navigation limits, local conditions, and insurer appetite.
Which inputs usually change the premium most?
Cruising area, usage (charter vs pleasure), vessel age, and length typically have the largest impact. Claims history and deductible choices also matter, especially when combined with higher-risk navigation.
Why does a higher deductible reduce the premium?
A higher deductible shifts more loss cost to the owner, lowering expected insurer payouts. The model reduces premium when the deductible exceeds a reference level tied to insured value, showing a realistic planning trade-off.
How should I set the insured value?
Use your agreed value or the amount you would want insured for a total loss. If you are unsure, test a range around your target value to understand how sensitive the annual estimate is.
Do add-ons always make sense?
Not always. Add-ons are most useful when the exposure is relevant: towing in remote cruising, pollution for higher traffic areas, or crew medical for staffed operations. The breakdown helps you judge cost versus benefit.
Can I use this for multiple yachts or renewals?
Yes. Run each vessel as a separate scenario, export CSV for comparisons, and store PDFs for recordkeeping. For renewals, update survey age, refit year, claims, and navigation plans to reflect current risk.
