# Marine Insurance Cost

> Marine insurance is priced on the vessel, the waters and the survey. Agreed value against actual cash value, and where claims fail.

## Key facts

- Agreed value and actual cash value produce different settlements at a total loss, and which applies is fixed at inception.
- Navigation limits define where cover responds, and a passage outside them can leave a vessel effectively uninsured.
- Insurers set a maximum age for a survey, and an out of date survey or uncompleted recommendations can suspend cover.
- Named windstorm deductibles are frequently separate from and larger than the standard deductible.
- Wreck removal and salvage costs can exceed the hull value, so the limit for them matters independently of the vessel's insured value.

## Data

- What underwriters price a marine risk on, and the terms that decide claims, 2026. Methodology: This table describes how marine cover is rated and structured. It quotes NO premium or rate, because marine risks are priced individually on the vessel, its value, navigation area, use, berthing and the owner's experience and claims record, and no public source sets a market rate. Survey requirements are described as insurer conditions, which vary by insurer and by vessel age, so the table directs you to ask rather than asserting a maximum age. Association references point at marine surveyors' bodies as starting points for finding a qualified surveyor rather than as endorsements. Nothing here is insurance advice.

## About

- Marine Insurance Cost is an introducer site. We are not an insurer or a broker and we do not advise, arrange or recommend any policy, cover or firm: we introduce you to insurance brokers by passing your details to them, and they deal with you directly. We may be paid a commission for that introduction by the firm we introduce you to, and it never changes the premium you are quoted. Nothing here is insurance, legal or survey advice. No premium is published on this site because marine risks are rated individually on the vessel, its value, navigation area, use, berthing and the owner's record. Policy terms including valuation basis, navigation limits, survey conditions and deductibles are terms of whichever policy you buy; read the wording rather than relying on any summary, including this one.
