# Yacht War Risk Insurance
Standard yacht hull policies are written on an all-risks basis — but that coverage stops precisely where geopolitical risk begins. War perils, acts of terrorism, piracy by persons acting for political ends, and confiscation by foreign state actors are universally excluded from the standard Institute Yacht Clauses. For owners operating in or transiting waters flagged by the Joint War Committee (JWC), that exclusion is not a footnote. It is a material gap.
This page explains the mechanics of the exclusion, how the JWC Listed Areas system affects your cruising plan, what a war rider actually provides, and how placement works for private yacht owners.
Who Needs Yacht War Risk Coverage
The owner of a 55-meter motor yacht anchoring in Split has different risk exposure than the owner of the same vessel transiting the Bab-el-Mandeb Strait or anchoring off the Lebanese coast. The coverage need is not defined by vessel size or value alone — it is defined by cruising area.
War risk coverage becomes relevant for any yacht owner who:
- Plans to transit or operate in any JWC Listed Area
- Holds a cruising permit for Turkish, Israeli, Lebanese, or Egyptian territorial waters
- Plans passage through the Red Sea, Gulf of Aden, or Strait of Hormuz
- Is considering a Black Sea transit from Istanbul toward Odesa or Georgian ports
- Operates in the eastern Mediterranean above the 32nd parallel in waters affected by the Israel-Gaza conflict and associated regional tensions
- Charters to flag-of-convenience clients or operates under a flag that increases political exposure
An owner operating exclusively between French Riviera ports and the Balearics may not face the same urgency. But routes change, itineraries expand, and JWC listing status is updated without advance notice. The more prudent approach is to confirm war risk coverage before departing, not after the list has been updated.
The JWC Listed Areas System
The Joint War Committee is a standing committee of London market underwriters that maintains the Hull War, Strikes, Terrorism and Related Perils Listed Areas. These are geographic zones where the committee has determined that the baseline war risk is elevated enough to require separate premium treatment and, in some cases, prior notice or exclusion from standard hull coverage.
When a body of water or coastal zone is added to the JWC list, the standard hull policy's automatic war risk exclusion is reinforced by market convention: no London market insurer will treat an incident in a Listed Area as an ordinary hull claim. Owners and operators are expected to hold a separate war risk endorsement that specifically reinstates coverage for the Listed Area in question.
As of the date of this publication, JWC Listed Areas relevant to private yacht owners have included the following zones. The list is revised periodically and owners should confirm the current status with their broker before departure:
- Red Sea and Gulf of Aden (Houthi threat environment)
- Black Sea (Russian naval operations, mine hazard)
- Strait of Hormuz and Gulf of Oman
- Gulf of Guinea (western African coastal waters)
- Portions of the eastern Mediterranean including Lebanese coastal waters
The JWC list is not static. Following the outbreak of the Gaza conflict in late 2023, portions of the eastern Mediterranean were added or had their status elevated. The Red Sea listing was similarly tightened after Houthi missile and drone attacks on commercial shipping accelerated through 2024. Yacht owners transiting these waters without reviewing current JWC status assume uninsured risk.
What Standard Hull Policies Exclude
The standard Institute Yacht Clauses — the policy form used by the overwhelming majority of private yacht insurers in the London market and its U.S. equivalents — incorporate the Institute War and Strikes Exclusion Clauses. These clauses remove from coverage:
- Loss or damage caused directly or indirectly by war, civil war, or revolution
- Loss caused by any weapon of war employing atomic or electromagnetic technology
- Capture, seizure, arrest, restraint, or detainment by any state actor or political faction
- Derelict mines, torpedoes, bombs, or other weapons of war (even if the conflict has ended)
- Loss arising from civil strife, insurrection, or politically motivated acts
- Piracy — note: the standard hull clause treats piracy ambiguously; London market practice often covers piracy under the hull clause, but in JWC Listed Areas this is contested
The practical consequence: a superyacht hit by drone shrapnel in Yemeni waters has no hull claim under its standard policy. A vessel seized by Iranian Revolutionary Guard Corps naval units in the Strait of Hormuz has no P&I claim for its crew under a standard protection and indemnity policy. The exclusions are absolute.
Policy Mechanics: Hull, P&I, and the War Rider
Yacht war risk coverage is typically structured in three layers, each of which operates differently in terms of placement, underwriter, and trigger.
Standard hull and P&I. The base policy covers the hull (agreed value or market value), third-party liability, and crew/passenger liability for ordinary marine perils. This is placed with admitted or surplus lines yacht insurers. For eligible vessels, this placement can be handled directly by a licensed P&C producer.
War risk rider (hull reinstatement). A separate endorsement or standalone policy that reinstates hull coverage for named war perils. This is placed with specialist war risk underwriters — predominantly Lloyd's of London syndicates with expertise in marine war. In the U.S. market, accessing these underwriters requires routing through a wholesale surplus lines broker. The war rider is quoted separately and is usually calculated as a percentage of the hull's agreed value, with the percentage varying materially based on the vessel's cruising area and the current JWC status of that area.
P&I war risk extension. Standard P&I policies also exclude war perils. For vessels operating in JWC Listed Areas, a separate P&I war risk extension must be arranged to cover crew injury, passenger liability, and pollution liability arising from a war peril incident. This is similarly placed through the wholesale channel.
Coverage Stacking: How Placement Works
For a private yacht owner, the coverage program is assembled in two distinct channels that operate in parallel.
The primary hull and P&I placement — covering all non-war perils — is handled directly by a licensed marine P&C producer. Josh holds the applicable P&C license and writes yacht hull and P&I policies directly with admitted carriers in relevant states.
The war rider — the surplus lines endorsement reinstating war perils — routes through a wholesale broker partner. This is a regulatory requirement: surplus lines products accessed via Lloyd's of London or non-admitted specialty markets require a licensed wholesale intermediary in the chain. The wholesale broker maintains the Lloyd's market relationships and processes the slip. The retail producer (Josh) coordinates the stacking of both policies so coverage is continuous with no gaps.
Owners should understand that the war rider and the hull policy may have different notice requirements, different claims handlers, and different dispute resolution forums (London arbitration for Lloyd's-based war risk; U.S. federal maritime court for admitted hull). These differences matter at claim time and should be understood before departure.
Claims: What Happens When Something Goes Wrong
A war risk claim on a private yacht will follow a materially different path than a collision or grounding claim.
Immediate steps. The owner or captain should notify both the hull underwriter and the war risk underwriter simultaneously. In a JWC Listed Area incident, there is often ambiguity at first — it is not always immediately clear whether an explosion, a collision, or a fire has a war-related cause. Both policies should be notified to preserve all rights.
Cause determination. War risk claims often turn on the question of proximate cause. Was a vessel struck by a mine that is properly characterized as a derelict weapon of war, or does it fall under hull? This question is frequently contested between underwriters. An experienced claims solicitor — not merely a local marine surveyor — is typically engaged.
Survey and documentation. Both underwriters will appoint surveyors. In a Listed Area, reaching the vessel for survey may require coordination with local maritime authorities, military escort, or remote survey via photographic and electronic evidence. The claims process can be extended as a result.
Subrogation and state actors. If a government entity is responsible for the loss — confiscation by a coastal state, damage from a military operation — the war risk insurer may pursue diplomatic or arbitral channels. These processes have long timelines. Owners should not expect rapid resolution in politically complex incidents.
Market Context
The yacht war risk market has remained functional but has repriced materially since 2023. The combination of Houthi activity in the Red Sea, unresolved Black Sea hazards from the Ukraine conflict, and increased eastern Mediterranean tension has led London syndicates to:
- Increase war risk rider premiums for eastern Mediterranean and Red Sea transits, with the largest movements affecting vessels with planned transits through the Bab-el-Mandeb Strait or extended Lebanese coastal operations
- Require prior notification (typically 48–72 hours) before a vessel enters a JWC Listed Area
- In some cases, restrict coverage or require additional security vetting for vessels planning extended Red Sea or Gulf of Aden passages
Owners planning to transit restricted waters are advised to engage their broker well in advance of departure — not to arrange coverage at the last minute. The prior-notice requirement is a condition of cover, and missing it can void the war rider entirely for an incident occurring during a transit entered without proper notification.
Request a War Risk Review for Your Yacht
If your cruising plan includes any JWC Listed Area — or if you are uncertain whether your planned route passes through elevated-risk waters — the first step is a review of your current hull policy's war exclusion clauses and a comparison against the current JWC list.
Josh holds the P&C license to write your primary yacht hull and P&I directly. The war rider — the Lloyd's-backed surplus lines endorsement that reinstates war peril coverage — is arranged through his wholesale broker partner. Both policies are coordinated under a single program so there are no gaps.
