Key takeaways
– The York–Antwerp Rules (YAR) are an internationally accepted set of rules for declaring and adjusting “general average” losses when property is deliberately sacrificed or expenses are incurred to save a maritime venture.
– Three conditions must be met to invoke YAR: (1) imminent peril to the ocean venture, (2) a voluntary sacrifice or expenditure to avoid that peril, and (3) success in avoiding the peril.
– YAR are typically incorporated into bills of lading, charterparties and marine insurance policies to establish procedures for apportioning costs among interests that benefited.
– Practical steps for an incident: declare general average, preserve evidence, appoint an average adjuster, obtain guarantees, prepare documentation, and settle contributions after adjustment.
What are the York–Antwerp Rules?
The York–Antwerp Rules are a standard, internationally-used set of rules that provide a uniform framework for the declaration and adjustment of general average. General average is the longstanding maritime principle that when a deliberate sacrifice or extraordinary expenditure is made for the common safety of a sea voyage, the resulting loss or expense must be shared proportionately by all parties who benefit from that action (shipowner and cargo interests).
The Rules themselves are not a law but a contractual, procedural scheme incorporated into contracts of carriage, charterparties and insurance certificates. The most recent consolidated version commonly used is York–Antwerp Rules 2016, although older versions (1994, 2004) remain referenced in older contracts.

Core principles (the three conditions)
For general average under the York–Antwerp framework to apply, all three elements must generally be present:
1. Imminent peril — There must be a real and present danger to the ship, cargo or voyage (e.g., threat of sinking, fire, severe storm).
2. Voluntary action — A deliberate and voluntary sacrifice of property or incurrence of an extraordinary expense must be made to avoid the peril (e.g., jettisoning cargo, cutting away mast, towing/salvage costs).
3. Successful outcome — The sacrifice or expense must effect the purpose of preserving the common venture (i.e., the dangerous situation is avoided or mitigated).
Distinguishing general average from similar concepts
– General average: Loss or expenditure voluntarily and reasonably incurred for the common safety; shared proportionately among all interests that benefited.
– Particular average: Partial loss or damage borne by the owner of the damaged goods alone (unless covered by insurance or contract).
– Salvage costs: Costs paid to salvage services; may be treated separately or included in a general average adjustment depending on the circumstances and contractual wording.
When and where YAR are used
– Bills of lading and charterparties often contain an express clause incorporating “York–Antwerp Rules” to determine how general average incidents are handled.
– Marine cargo insurance policies normally cover general average contributions if the policy includes such coverage; otherwise cargo owners may face immediate demands for cash or guarantees to secure delivery.
– YAR apply worldwide whenever the contractual documents incorporate them or when parties adopt them by agreement.
Practical steps to follow when an incident occurs (step-by-step)
1. Immediate shipboard response (safety first)
• Follow all safety and emergency procedures to protect lives and the vessel.
• Preserve evidence of decisions, times, witness statements, logs and photographs.
2. Decision to sacrifice and declaration
• If the master/owner decides to sacrifice cargo or incur extraordinary expenditure for the common safety, the master or owner should declare general average as early as practicable.
• The declaration should be made in writing and communicated promptly to all interested parties (charterer, cargo interests, P&I clubs, insurers).
3. Preserve and document
• Keep detailed records: the master’s protest, deck log, cargo manifest, surveyor reports, cost invoices, salvage receipts, photographs, radio/bridge records, and witness statements.
• Engage surveyors immediately (both shipowner’s and cargo/insurer’s surveyors may inspect).
4. Appoint an average adjuster
• The parties (or the declaring party) normally appoint an independent average adjuster (licensed general average adjuster) to collect data, quantify losses and prepare the general average adjustment according to the adopted version of the York–Antwerp Rules.
• The adjuster prepares a GA statement setting out sacrifices, extraordinary expenses, and the basis for apportionment.
5. Security and GA bond (guarantee)
• Cargo owners or their insurers will typically be required to provide security (cash deposit, GA bond, or bank guarantee) to the shipowner or their agent before cargo is released.
• The security amount is often based on a provisional estimate of the cargo’s contribution to general average.
6. Adjustment and apportionment
• The average adjuster compiles values of all contributing interests (ship, freight, and all cargo saved) and apportions the general average loss proportionately in accordance with the YAR and the adopted rules.
• The adjuster issues the final adjustment showing each interest’s contribution and details of deductions (e.g., particular average not recoverable).
7. Settlement and release
• Once security is posted and negotiations are concluded, cargo can be released.
• Final settlement follows the adjuster’s award; payments are made to the shipowner (or to creditors who provided salvage services), or insurers may reimburse the insured shippers according to their policies.
8. Post-event review and insurance recovery
• Cargo owners submit claims to their insurers for reimbursement if their policies cover general average.
• P&I clubs and hull insurers may meet their members’ liabilities depending on cover terms.
What losses and expenses are typically recoverable under YAR
Recoverable items commonly include:
– Value of jettisoned cargo and wrecked property specifically sacrificed
– Extraordinary expenses reasonably and necessarily incurred to preserve the venture (e.g., tugs, salvage and firefighting costs, repairs made to continue voyage)
– Cost of lightering and transhipment necessary to save the voyage
Non-recoverable items often include:
– Ordinary wear and tear, negligence-based losses, pre-existing defects, and losses not incurred for common safety.
Documentation checklist for a GA claim
– Master’s protest and ship’s log
– Bill(s) of lading and charterparty
– Cargo manifests and invoices
– Surveyor and salvage reports
– Receipts and invoices for expenses (tugs, repairs, salvage)
– Photographs, witness statements and voyage data
– Insurance policies and P&I notifications
– GA declaration and appointing correspondence for the average adjuster
Sample contractual language
Many bills of lading use short incorporation clauses such as:
“All terms, including apportionment of general average, shall be subject to the York–Antwerp Rules 2016 where applicable.”
(Adapt to the version you intend to incorporate; ensure the year is explicit.)
Practical tips by role
– Shippers / cargo owners
• Ensure marine cargo insurance explicitly covers general average contributions and salvage.
• Keep clear records of cargo value and supporting invoices.
• Understand the bill of lading and whether it incorporates a particular version of YAR.
• Be prepared to provide a GA bond or guarantee quickly to avoid cargo detention.
• Shipowners / carriers
• Declare general average promptly and transparently where appropriate.
• Preserve exhaustive documentation and engage an independent average adjuster.
• Communicate requirements (security, estimated contributions) to cargo interests and insurers.
• Insurers and P&I clubs
• Respond rapidly to GA declarations; arrange guarantees where covered.
• Coordinate with average adjusters and surveyors to verify the reasonableness of expenses and sacrifices.
Common pitfalls and disputes
– Failure to meet the three YAR conditions: a declaration of GA can be contested if the peril was not imminent, the act was not voluntary, or the act failed to preserve the venture.
– Disputes over valuations: cargo value, ship’s saved value and freight can be contentious and affect contribution shares.
– Time delays: slow documentation or contesting guarantees can cause cargo detention and additional expenses.
Example (simplified)
Suppose a ship in a storm requires jettisoning cargo worth $200,000 in order to save the ship and remaining cargo. The remaining saved cargo is worth $800,000 and the ship (with bunkers and freight) is valued for GA purposes at $1,000,000. Total value saved = $1,800,000. The $200,000 general average sacrifice is apportioned among all contributors in proportion to their saved values:
– Ship’s share: 1,000,000 / 1,800,000 × 200,000 = $111,111
– Saved cargo’s share: 800,000 / 1,800,000 × 200,000 = $88,889
(Then contributions are allocated among cargo owners in proportion to each cargo’s saved value.)

Conclusion
The York–Antwerp Rules are a practical, internationally recognized mechanism for handling the difficult question of who pays when property is deliberately sacrificed to save a voyage. For effective management when a GA event occurs, parties should act urgently to preserve evidence, declare GA promptly, appoint an experienced average adjuster, and coordinate with insurers and P&I clubs to arrange guarantees and expedite cargo release. Clear contractual wording and appropriate insurance coverage are essential preventive steps to reduce delay, expense and disputes.
