A standard hull policy stops at the edge of a war zone. Understanding what it excludes — and what separate war-risk and kidnap-and-ransom cover restore — is the difference between a safe transit and an uninsured one.
An owner routes a delivery voyage through the Red Sea to save a fortnight, only to discover after a drone incident that the hull policy never covered it. War, terrorism and piracy sit among the standard exclusions of almost every yacht hull-and-machinery contract, and the moment the vessel crosses into a listed high-risk zone without separate cover in place, the most valuable asset on the water is sailing entirely at the owner's own risk.
Yacht hull-and-machinery cover is written on standard marine wordings that carry a near-universal set of war and strikes exclusions. In practice the policy will exclude loss or damage caused by war, civil war, revolution and hostilities; by the detonation of mines, torpedoes and other derelict weapons of war; by capture, seizure, arrest, restraint or detainment; by terrorism and politically motivated acts; and, critically for the modern owner, by piracy and armed robbery at sea.
These exclusions are not a drafting oversight; they are a deliberate carve-out of a class of risk that ordinary marine underwriters will not price alongside collision and fire. The consequence is stark. A yacht that suffers a piracy attack, a mine strike or a seizure while relying on hull cover alone has no valid claim for that loss. War and piracy risk must be bought back separately, either through an add-on to the same programme or through a dedicated war-risk market that specialises in exactly this exposure. An owner who does not ask the question is presumed to be carrying the risk personally, and few realise it until a claim is declined. The exclusions also apply the moment the vessel enters an area where these perils are active, regardless of whether an incident has yet occurred, so the gap opens on entry rather than on attack. This is why the war-risk question belongs at the itinerary stage, not the claims stage.
A war-risk policy buys back the perils the hull contract carved out, and for the modern superyacht it is piracy — not naval warfare — that dominates the exposure. A properly structured war and piracy cover typically responds to the following.
War-risk cover is usually written on an annual basis for the vessel's ordinary trading area, with high-risk transits declared and rated separately. It sits alongside the hull policy rather than replacing it, so the two must be read together to confirm there is no gap where one ends and the other is meant to begin. Cover is normally written for an agreed insured value, and the war-risk sum insured should match the hull value so that a piracy total loss pays in full rather than to a lower cap.
War-risk underwriters map the world into trading areas and maintain a schedule of listed excluded or high-risk zones — the Joint War Committee listed areas that the London market updates as geopolitics shift. Entering one of these areas is not covered under the ordinary premium; the transit must be declared in advance and rated on its own, and sailing in unannounced can void the response. The table below sets out the pattern of how zones are treated and rated. Figures are indicative market ranges, not quotes.
| Navigation zone | Typical status | Additional-premium treatment |
|---|---|---|
| Red Sea & Gulf of Aden | Listed high-risk / often excluded | Declared transit, breach premium 0.10%–0.75%+ of hull value per passage; armed guards frequently required |
| Southern Red Sea & Bab-el-Mandeb | Elevated / conditional | Case-by-case; some markets decline; premium can exceed 1% of value in acute periods |
| Gulf of Guinea / West Africa | Listed high-risk | 0.20%–0.80% of value per transit; kidnap exposure drives K&R purchase |
| Parts of the Sulu & Celebes Seas | Listed high-risk | Declared transit; escort and routing conditions common |
| Standard Med / Caribbean cruising | Within ordinary trading area | Included in annual war-risk premium; no breach charge |
The precise list moves. What matters is the discipline: confirm whether a planned area is listed before the passage, not after, because the additional-premium mechanism only works if the transit is declared in advance.
The mechanism that governs high-risk transits is the additional-premium, or “held covered”, provision. The annual war-risk policy covers the vessel's ordinary trading area; the moment it intends to enter a listed area, the owner or manager must notify underwriters and agree an additional premium for that specific passage before crossing the boundary. This is the breach-notification duty, and it is a condition of cover, not a courtesy.
The additional premium is expressed as a percentage of the insured hull value for the duration of the transit — frequently in the range of 0.05% to 1% or more of value, escalating sharply in periods of active conflict. On a US$60m yacht, even a 0.25% breach premium is US$150,000 for a single passage, before the cost of embarked armed security, routing advice and hardening measures that underwriters commonly require as a condition of quoting at all. Underwriters may also impose a strict notice period, minimum transit speeds, mandatory routing through advised corridors and the carriage of a vetted maritime-security team. Failure to notify, or entering a listed area without agreeing terms, typically suspends cover for the duration of the breach — leaving the vessel uninsured for precisely the risk it faces. The notification duty usually falls on the manager or captain as well as the owner, so the reporting line should be agreed before departure and the underwriter's confirmation held on board for the passage.
War-risk cover protects the vessel; it does not, on its own, protect the people aboard against being taken and held for ransom. That is the province of a separate kidnap and ransom, or K&R, policy — a specialist and highly confidential line that responds when owners, guests or crew are seized in a piracy or hostage event. Its confidentiality is itself a condition: disclosing that a K&R policy exists can void it, because a known ransom facility raises the target value of those it protects.
A K&R policy typically reimburses the ransom actually paid, covers the cost of expert response consultants who manage the negotiation, and funds crisis expenses, medical care, legal liability and lost income during captivity. For a superyacht transiting the Gulf of Guinea or the wider Indian Ocean, K&R is bought alongside war-risk cover precisely because the two answer different questions: one restores the hull, the other brings the people home. Limits are set per incident and in the aggregate, and the response consultants — not the owner — run the negotiation, which is where the real value of the cover lies. Family offices increasingly treat K&R as standard for any principal whose itinerary touches a listed zone, and often extend it to shore excursions and tenders as well as the vessel itself, since the exposure follows the people rather than the hull.
The owners who transit high-risk waters cleanly are those who treat insurance as part of route planning rather than an afterthought. The sequence is deliberate, and each step conditions the next.
Handled this way, an at-risk transit becomes an insured, planned passage rather than an uninsured gamble. The premium is real and the conditions are strict, but both are knowable in advance — and the alternative is sailing the most valuable asset an owner holds into the one class of risk the ordinary policy expressly refuses to carry.
We source and structure war-risk, piracy and kidnap-and-ransom cover through a private network of specialist marine underwriters and security advisers, under NDA. We screen your itinerary against the listed high-risk zones, read the hull and war-risk wordings together to close any gap, negotiate the breach premium and security conditions for each declared transit, and return a single all-in figure. Give us the route and the vessel, and we tell you plainly what the at-risk legs will cost to insure and how to structure them.

No. Standard hull-and-machinery policies carry near-universal war, terrorism and piracy exclusions, so loss from a piracy attack, mine strike, seizure or hostilities is not covered. That risk must be bought back separately through a dedicated war-risk policy, either as an add-on or through a specialist war-risk market.
It is an additional premium charged when a yacht enters a listed high-risk zone that its ordinary war-risk cover excludes. The transit must be declared to underwriters in advance and rated separately, typically as a percentage of hull value — often 0.05% to 1% or more per passage — before the vessel crosses the zone boundary.
The London market's Joint War Committee lists areas such as the Red Sea and Gulf of Aden, the southern Red Sea and Bab-el-Mandeb, the Gulf of Guinea and parts of West Africa, and stretches of the Sulu and Celebes Seas. The list is revised as geopolitics shift, so a route should be screened against the current schedule before departure.
K&R is a separate, confidential policy that responds when owners, guests or crew are seized. It reimburses the ransom paid, funds expert response consultants who run the negotiation, and covers crisis, medical, legal and loss-of-income expenses. Its existence must be kept secret, as disclosure can void the cover and raise the target's value.
Entering a listed area without notifying underwriters and agreeing the additional premium typically suspends cover for the duration of the breach, leaving the vessel uninsured for the exact risk it faces. Breach notification is a condition of the policy, not a formality, so the transit must be declared and rated before the boundary is crossed.
