P&I vs Hull and Machinery: Where Each Policy Starts and Stops

Most owners describe hull and machinery and P&I as two halves of one wall. Buy both, and everything on the water is behind you. That description is comfortable and it is wrong in a specific, expensive way.

The two covers were not designed as a matched pair. Hull cover grew out of the London marine market's willingness to insure the ship as an asset, and it stopped where underwriters in the 1800s decided their appetite stopped. P&I grew out of shipowners clubbing together to carry the liabilities the hull market had refused, which is why the clubs still describe themselves as mutuals rather than insurers.

The seam between the two moves depending on which hull form you signed, what your club rules say, and whether anyone checked that the two documents line up. Losses fall into that seam more often than owners expect, and they fall into it at the worst moment, when a surveyor is already on board and a claimant is already asking for security.

Key Facts: The Hull and P&I Boundary

What does hull and machinery insurance actually pay for? Physical loss of or damage to your own vessel from insured perils, plus your proportion of general average and salvage, plus three-fourths of collision liability to another vessel. Under Institute Time Clauses (Hulls) 1/10/83, those sit at clause 6, clause 11 and clause 8 respectively, subject to policy terms and conditions.

What does P&I cover that hull does not? Third party liabilities arising from operating the ship: crew injury, illness, death and repatriation, cargo claims brought against the carrier, pollution, wreck removal, damage to fixed and floating objects, stowaways, fines and collision liabilities that hull terms exclude or exhaust.

Why is collision liability split three-fourths and one-fourth? Nineteenth century hull underwriters would not write more than three-quarters of a shipowner's liability for damage to the other vessel, so the remaining quarter fell to the clubs. ITC-Hulls clause 8.1 indemnifies three-fourths, and the balance is picked up under the P&I entry where the club rules expressly say so.

What does ITC-Hulls clause 8.4 exclude from hull collision cover? Removal or disposal of obstructions, wrecks and cargoes; property other than other vessels and property on them; the cargo, other property and engagements of the insured vessel; and loss of life, personal injury, illness, pollution and contamination other than to the colliding vessel and property on her. Every one of those categories is P&I territory.

What caps hull collision cover? Clause 8.2.2 limits underwriters to three-fourths of the insured value of your own vessel for any one collision. A collision liability that exceeds your hull value is not a hull claim above that ceiling, and excess collision liability cover under the P&I entry is what stands behind it.

How large is the liability side? Claims above the individual club retention of $10 million are shared under the International Group Pooling Agreement, which the Group states provides a mechanism for sharing claims up to approximately $8.9 billion. The Group comprises twelve clubs covering around 87% of the world's ocean-going tonnage on its own figures.

For the liability side in full, see what P&I insurance is and how the clubs work. For the asset side, see hull and machinery insurance, and for the statutory framework behind both, see the Marine Insurance Act 1906.

Two policies asking two different questions

Hull and machinery answers one question: has the ship been physically damaged or lost by something the policy insures against? The answer turns on the peril, the due diligence proviso, and the deductible, and the money runs to you as owner because you own the damaged property.

P&I answers a different question: is the shipowner legally liable to someone else because of the operation of the ship, and has that liability been paid? The answer turns on the club rules, the terms of entry, and the pay-to-be-paid principle confirmed by the House of Lords in The Fanti and The Padre Island in 1990.

Those questions do not overlap as neatly as the phrase "hull and P&I" suggests. A grounding that opens your bottom plating and spills bunkers into a Malaysian anchorage generates a hull claim for the plating and a P&I claim for the oil, and the two are handled by different adjusters, on different evidence, to different time bars.

Getting the split right matters commercially as well. A claim placed against the wrong policy delays payment, and in a hard renewal market it also lands on the wrong loss record, which affects the rating conversation you have next February.

The collision seam

Collision is where the boundary is at its sharpest and where owners most often assume more cover than they have. ITC-Hulls 1/10/83 clause 8.1 indemnifies you for three-fourths of any sum you pay to another party for loss of or damage to any other vessel or property on any other vessel, delay to or loss of use of any other vessel or property on her, and general average, salvage or salvage under contract of any other vessel or property on her.

Clause 8.2.1 provides that where both vessels are to blame and neither is limiting liability by law, the indemnity is calculated on the principle of cross-liabilities, as if each owner had been compelled to pay the other's proportion. Clause 8.2.2 then caps underwriters at three-fourths of the insured value of your vessel for any one collision, and clause 8.3 deals with legal costs incurred with underwriters' consent.

Three separate gaps open out of that structure. The missing quarter of the liability itself, the excess above three-fourths of your insured value where the other ship is worth far more than yours, and everything clause 8.4 pushes out of the hull policy altogether.

Gard's own claims guidance describes the same interface from the club side, noting that the addition of the one-fourth to the P&I entry has to be explicit in the terms of entry rather than assumed. That is the single most useful sentence in this article. Ask your broker to show you where in your entry it appears.

What clause 8.4 pushes across the line

Read that table alongside your entry rather than alongside a brochure. The categories on the left are removed from your hull policy by the wording itself, and nothing in the hull placing slip puts them back.

The boundary table

This is the version to hand to your broker. Take an exposure, find it in the left column, and ask which document responds and on what terms.

Two rows in that table describe things neither policy pays. Loss of hire is the obvious one, and owners on time charter often discover it only after an engine casualty has already put them off hire.

Wreck removal is nobody's clause until you read the entry

Removal of your own wreck is excluded from English hull terms and sits with the club. Gard's comparison of market forms makes the point that this is a market convention rather than a law of nature: Norwegian and German hull conditions treat removal of the other vessel's wreck as a collision liability, while English and Swedish conditions do not.

If you are trading on ITC-Hulls with a Norwegian charterer's expectations, or on the Nordic Plan with an English hull broker's assumptions, that difference can quietly leave a hole. It is worth asking the question at placing rather than at the wreck.

The exposure itself is shaped by international convention. The Nairobi International Convention on the Removal of Wrecks 2007 gives a coastal state a direct right of recovery against the registered owner, and the 1996 Protocol to the Limitation of Liability for Maritime Claims Convention, whose limits rose by 51% with effect from 8 June 2015, is where an owner would normally look to cap that recovery. Article 18(1) of that Convention lets a contracting state reserve wreck and cargo removal claims out of limitation altogether, and a number have done so, so the cap an owner assumes may simply not be available in the state where the casualty happens.

Crew, pollution and cargo: the liabilities hull never touched

The three largest liability heads on any club's claims record never appear in a hull policy at all. Crew claims run from injury and illness through to repatriation and the financial security certificates required under the Maritime Labour Convention 2006 as amended, which clubs issue on behalf of members.

Pollution is a statutory exposure as much as a commercial one, and the International Group's 2026/27 reinsurance structure carries a distinct oil pollution layer sitting inside the wider programme. Coastal states in the region will look for certificates before they look for a policy, and a vessel calling at a Malaysian or Singaporean port without them will not be trading for long.

Cargo claims are the head that most often surprises owners who have come across from the cargo side of the trade. The club responds to your liability as carrier, which means the defences in your bill of lading are part of your insurance position. Widen the contract beyond Hague-Visby terms without telling the club, and you have widened an exposure the club may decline to follow.

That interaction runs both ways. Cargo interests carrying their own marine cargo insurance recover from their own underwriters and then subrogate against the ship, which is how a cargo loss becomes a P&I file. The mechanics of that recovery are set out in cargo liability and P&I and in carrier liability limits.

Where the boundary moves

The three-fourths convention is a feature of English hull forms, not of hull insurance generally. Under the Nordic Marine Insurance Plan an owner can insure the whole collision liability with hull underwriters, although death, injury and pollution still fall to the club.

The International Hull Clauses 01/11/03 keep 3/4ths collision liability as the standard position in clause 6 but provide an optional amendment at clause 38 taking it to 4/4ths where underwriters have expressly agreed in writing. Where that option is exercised, the P&I entry should be adjusted so you are not paying twice for the same quarter.

ITC-Hulls 1/11/95 sits between the two. It introduced a Classification clause at clause 4 and pushed Termination down to clause 5, so a reference to "clause 5 termination" is a 1995 reference and a reference to "clause 4 termination" is a 1983 one. Small point, and it decides which document a lawyer is actually reading.

Owners moving between English and Nordic conditions should reconcile the entry against the new hull form at the same time, rather than a year later at the next P&I renewal.

What to check if you operate in Malaysia or Singapore

Arrest in Singapore runs on the in rem jurisdiction conferred by the High Court (Admiralty Jurisdiction) Act 1961, and Singapore practice accepts letters of undertaking from reputable and internationally recognised P&I clubs as security to release the ship. That acceptance rests on agreement between the parties rather than on any provision of the Act itself. It still makes club membership a practical trading asset in the port rather than a balance sheet item, because it is what gets a ship moving again after an in rem writ.

Malaysian domestic trading brings its own layer. A foreign vessel carrying goods between places in Malaysia needs a Domestic Shipping Licence from the Domestic Shipping Licensing Board under section 65L of the Merchant Shipping Ordinance 1952, and an owner or charterer who assumes an exemption applies can find the vessel detained rather than merely uninsured.

Both markets are dense with third party property. MPA Singapore reported 44.66 million TEU of container throughput and 3.22 billion gross tonnage of vessel arrivals in 2025, with marine fuel sales of 56.77 million tonnes. Every berth, bunker barge and crane in that traffic is a fixed or floating object your hull policy will not pay for.

Congestion adds contact risk in both countries, which is the practical reason to read Port Klang and PSA congestion in 2026 alongside your entry rather than as a separate operational issue.

Trade mix matters too. Owners lifting refined product and chemicals out of Pasir Gudang and the Singapore anchorages carry a pollution profile that sits almost entirely on the club side of the boundary, which is worth reading against the cargo exposures set out in energy and petroleum cargo insurance.

Frequently Asked Questions

Does my P&I entry automatically cover the one-fourth collision liability?

No, it has to be expressly included in the terms of entry. Club practice is to add the one-fourth running down clause liability and excess collision liability where the member asks for it, and Gard's claims guidance makes clear the addition must be explicit. Ask your broker to point to the wording rather than confirm it verbally.

What happens if collision liability exceeds my vessel's insured value?

Hull underwriters stop at three-fourths of your insured value for any one collision under ITC-Hulls clause 8.2.2. Liability above that ceiling falls to excess collision liability cover under the P&I entry, subject to the club rules. This matters most for small vessels that can strike very large ones.

Is wreck removal a hull claim or a P&I claim?

Removal of your own wreck is a P&I claim under English hull terms, and clause 8.4 of ITC-Hulls also excludes removal of obstructions and wrecks from collision cover. Some continental hull conditions treat removal of the other vessel's wreck differently. Check which form you are actually on before assuming.

Do I still need hull cover if my vessel is fully entered with a club?

Yes, because clubs exclude damage to the member's own property. A P&I entry answers your liability to other people and never repairs your own plating, machinery or equipment. The two covers are bought together for that reason, not because either is optional.

Which policy pays for cargo damaged on my own ship?

Neither pays the cargo owner directly. Cargo interests claim on their own cargo policy or against you as carrier, and if they claim against you, your P&I entry responds to that liability subject to policy terms and conditions. ITC-Hulls clause 8.4 expressly removes the cargo of the insured vessel from hull collision cover.

Does general average sit with hull or with P&I?

Both, in different portions. ITC-Hulls clause 11 covers the vessel's proportion of general average, salvage and salvage charges, reduced for any under-insurance. The club typically responds where the owner cannot recover cargo's proportion or where a shortfall arises, so the adjustment under the York-Antwerp Rules 2016 ends up split across both.

How high does P&I cover go?

Very high, by design. Claims above the individual club retention of $10 million are shared under the International Group Pooling Agreement, which the Group describes as sharing claims up to approximately $8.9 billion, with a separate lower limit for oil pollution. Individual limits and exclusions still depend on your terms of entry.

Voyage Conclusion

The gap between hull and P&I is the record of two markets deciding separately what each was willing to write, and the exposures that fell between them are still sitting there in clause 8.4 and in the three-fourths cap. An owner who can point to where the one-fourth, the excess collision liability and the wreck removal sit in their own documents has done the work that most owners assume their broker did.

Voyage places hull and machinery and protection and indemnity cover directly with the underwriters and clubs who write these risks in Malaysia and Singapore, and we will read the seam between them with you before a casualty does it for us. For the wider liability picture see marine liability insurance, and for the club system itself see what P&I insurance is. Send the two documents through the quote request form or on WhatsApp and we will come back within 24 to 48 hours.
