Recreational marine • Hull value, waters, and storage • Directional 2026 estimate
Boat Insurance Calculator
This boat insurance calculator produces an educational monthly and annual range from hull value, boat type, horsepower, waters, storage, liability limit, and deductible. It is not a binder and it is not a United Marine or carrier rate.
A homeowners policy may give small-boat liability on a lake. It usually will not replace a marine hull policy for a financed boat, a marina slip, coastal navigation, or a personal watercraft. Quote the boat the way you actually use it: freshwater trailer boat, wet-slip coastal cruiser, and offshore center console are different risks.
The primary quote button opens United Marine with Blake’s agent link. Bolt is a general personal-lines path and may not return boat markets.

Enter a realistic market value, not the original sticker price. Then calculate. Compare the range with a United Marine quote using the same navigation territory.
How the model works
Annual estimate starts at 1% of entered hull value, or $250 if value is blank. Liability adds a flat amount. Type, horsepower, waters, storage, age, deductible, safety course, and claims-free years then multiply. The displayed range is 85% to 115% of that midpoint.
| Input | Effect on the midpoint |
|---|---|
| Hull value | × 1.0% (or $250 if value is 0) |
| Liability $100k / $300k / $500k / $1M | +$0 / +$70 / +$120 / +$220 |
| PWC / cuddy / fishing / sail / pontoon | × 1.25 / 1.10 / 1.05 / 0.92 / 0.95 |
| Horsepower over 150 / over 300 | × 1.08 / 1.15 |
| Coastal / offshore waters | × 1.10 / 1.25 |
| Driveway / marina storage | × 1.04 / 1.12 |
| Age 10–19 / 20+ years | × 1.04 / 1.10 |
| Deductible $250 / $1,000 / $2,500 | × 1.06 / 0.92 / 0.82 |
| Safety course | × 0.95 |
| Claims-free years | −2% each, max five years |
Direct answer: Use the range to sanity-check a quote, not to bind coverage. A Gulf wet-slip boat with a percentage hurricane deductible will not price like a trailer bass boat on a Midwest lake. Tell the marine market if the boat is chartered, raced, lived aboard, or kept in a named-storm county.
What a boat policy usually includes
- Hull / physical damage — the boat, and sometimes the engine and installed equipment, after a covered loss.
- Liability (protection and indemnity) — injury and property damage you cause. Marinas often want $300,000 to $1 million.
- Medical payments — passenger medical bills, subject to the form.
- Uninsured boater — optional on many recreational forms.
- Towing and assistance — on-water towing is not automatic; read the cap.
- Trailer — may be scheduled or limited; roadside towing can be separate from water towing.
- Personal effects and fishing gear — usually sublimited.
- Wreck removal and fuel spill — ask whether they sit inside liability or need their own wording.
Coverage language varies. Compare forms on boat insurance comparison.
Agreed value versus actual cash value
Agreed value sets the total-loss amount when you buy the policy. Actual cash value pays depreciated market value at the time of loss. This calculator does not switch those bases; live quotes will. Financed boats and newer hulls are often written agreed value. Older runabouts may only be offered ACV.
Coastal policies can add a separate named-storm or hurricane deductible as a percentage of hull value. That cash number is not the $500 deductible in the form above.
Boat insurance calculator FAQs
Is this calculator a real quote?
No. It is an educational range. A premium exists only after a marine underwriter rates the boat, operators, and navigation territory.
Does homeowners insurance cover my boat?
Sometimes for a small, low-horsepower craft used on a lake, and usually not for hull value, PWC use, or coastal navigation. Read the homeowners watercraft exclusion.
Why is offshore more than freshwater?
This model applies a 25% offshore load and a 10% coastal load. Live hurricane and navigation warranties can be larger.
Does Bolt bind boat insurance?
Not necessarily. Use the United Marine agent link for a marine quote.
Should I insure a PWC the same way as a pontoon?
No. This model loads PWC 25% because theft and operator exposure differ. Quote the actual craft.
