Yacht insurance is a contract that pays for named losses on a named vessel, and nothing else. A typical policy covers the hull and machinery against physical damage, protects you if your yacht injures someone or damages another boat, and adds a short list of extras such as salvage and wreck removal. What it does not cover — wear and tear, gradual corrosion, unlicensed use, and most damage in named storm zones during hurricane season unless you buy that cover back — is where disputes happen.
The catch is that the cover depends on conditions you must meet, not just premiums you must pay. Insurers require surveys, set navigation limits, impose lay-up periods, and attach hurricane-season clauses with named-storm deductibles. Miss a condition and a claim can fail, even when the damage itself looks plainly insured. This guide sets out what the main sections of a policy actually do, and what to check before you sign.
What does a hull policy actually cover?
The hull section is the core. It pays to repair or replace the vessel itself after a sudden, accidental event: a grounding, a collision, a fire, a failed through-hull letting water in. Machinery damage from a sudden breakdown is usually inside this section, which is why insurers care about maintenance records. The trigger word is sudden. Damage that builds slowly — corrosion, osmosis, fatigue, a bearing wearing out over seasons — is treated as wear and tear, and wear and tear is excluded almost everywhere.
What counts as a yacht for these policies is broader than many readers assume. According to Yacht.com, any private leisure boat over 33 feet is generally considered a yacht, though mini yachts can enter the category from around 20 feet, and the average privately owned yacht sits between 35 and 70 feet. That matters for insurance because the same policy architecture — hull, liability, extras — scales from a 35-footer to a 200-footer; what changes is the survey depth, the deductible structure and the underwriting scrutiny.
Beyond the hull, most policies bundle agreed-value cover: the insurer and owner fix the vessel's insured value in advance, so a total loss pays that figure rather than a depreciated market value. Partial losses are usually paid on a repair-cost basis, often with the deductible applied. Ask which basis your policy uses before you sign, because the answer changes what a write-off actually pays.
What does liability cover, and why does it matter more than hull?
Liability is the section that protects everything else you own. If your yacht collides with another vessel, injures a swimmer, or damages a marina dock, liability pays the other party's claim and your legal defence. For most owners this is the section that justifies the premium, because a serious third-party claim can dwarf the value of the yacht itself. Crewed yachts add employers' liability for the crew, and charter operations add charterer's liability — a different contract with different limits. This connects to our earlier piece, Flag states and yacht registration: why the paperwork matters to guests.
Liability cover is also conditional. Navigation limits define where the vessel may go; operate outside them and you may be uninsured for that passage. The policy will also name who may helm. Lend the yacht to an unapproved skipper and the liability section may not respond. Before you sign, read the named-skipper clause and the navigation warranty — they are the two conditions owners most often breach without noticing.
What are hurricane-season clauses?
In storm-exposed regions, insurers write a specific set of conditions for hurricane season. Three mechanisms recur. First, a named-storm deductible: when a named storm causes the damage, you pay a percentage of the insured value rather than a flat sum — a materially larger cheque. Second, a windage limit: some policies cap or exclude cover for vessels left in the water in a defined storm zone during defined months. Third, a movement requirement: the policy may require the yacht to leave the zone, or a marina's storm plan to be followed, when a storm watch is issued.
The practical reading is this: the hurricane clause is not a price, it is a set of duties. If your policy requires relocation on a named watch, the duty falls on you or your captain, and the insurer will ask what was done. Owners who winter in the tropics should treat the hurricane section as the first thing to read, not the last. Where the policy is silent, ask in writing — silence is not cover.
Why do insurers require surveys?
A survey is an independent inspection of the vessel's condition, and insurers use it to price risk and set terms. For older or larger vessels, a full condition survey by an accredited marine surveyor is standard before cover is bound or renewed. The surveyor reports on the hull structure, machinery, safety equipment and sea-worthiness; the insurer then either accepts the risk, prices it with loadings, or imposes conditions — repair this, replace that — as a precondition of cover.
Survey requirements tighten with value and age, and they recur at renewal. An out-of-date survey is one of the most common reasons a renewal is delayed. Owners planning a refit should tell the insurer before the work: a documented refit can improve terms, while undisclosed modifications can void them.
What this means before you sign
Our analysis of how these policies fail is simple: claims rarely fail on the insured event, they fail on an unmet condition. So the pre-signature checklist is short and unglamorous.
- Confirm the valuation basis — agreed value or market value — and that the agreed figure reflects a current survey.
- Read the navigation limits and named-skipper clause against how the yacht is actually used.
- Read the hurricane-season section in full if the vessel winters anywhere storm-exposed, and note every duty it puts on you.
- Check the lay-up period: cover for a moored, unused yacht is often cheaper, but use outside the lay-up dates may be uninsured.
- Ask who pays for salvage and wreck removal — these are usually separate cover lines, and they are expensive to do without.
The strongest counter-argument to buying broad cover is cost: premiums on larger vessels are substantial, and a disciplined owner with a well-maintained boat may feel the exclusions will never bite. The numbers do not support that confidence. The exclusions that bite — wear and tear, out-of-zone operation, an unapproved skipper — are precisely the ones an ordinary season can trigger.
The honest total
Insurance is one line in the cost of running a yacht, and it interacts with the others. A vessel kept in a hurricane zone pays for it in deductibles and duties; a vessel with a current survey and clean maintenance records pays less and claims faster. If your use of the yacht involves guests and crew, the liability and employers' liability sections matter more than the hull — and if you are weighing the running costs of a crewed boat, our guide to crewed charter tipping: how much, when, and to whom covers the crew-side budget, while our charter section tracks what a week on the water actually costs. The paperwork that follows the vessel — its flag and registration — is covered separately in flag states and yacht registration: why the paperwork matters to guests, and the broader life-aboard costs sit in our life aboard section.
What the evidence supports is modest and worth stating plainly: cover is conditional, the conditions are readable, and the difference between a policy that pays and one that does not usually shows up in the documents before the damage does. What remains unknown in any individual case is the insurer's own wording — which is why the last read before signature should be yours, not your broker's summary of it.
