Superyacht Warranty Claims Against the Shipyard

Six months after a triumphant delivery, the hydraulics on the passerelle fail, a section of teak lifts, and the air-conditioning cannot hold temperature in the owner's cabin. The yard calls it fair wear and normal settling; you call it defective work still inside the guarantee period. Between those two positions sits the warranty — a clause everyone signed and few read closely — and the money you can recover turns entirely on how carefully it was written and how promptly you act.

The guarantee period and how it is structured

Most new-build and major-refit contracts carry a warranty, or guarantee period, running from the moment of delivery and acceptance. Twelve months is the historic norm; twenty-four is now common on larger custom builds, and some yards offer longer cover on the hull and specific structural elements while holding machinery and equipment to the shorter term. The clock starts at delivery, not at keel-laying or launch, so the date on the protocol of delivery and acceptance is the single most important figure in any later claim.

The structure matters as much as the length. A well-drafted warranty distinguishes between the yard's own workmanship and the equipment it installed under third-party manufacturer guarantees — engines, stabilisers, navigation, generators. The yard warrants its integration and installation; the maker warrants the unit itself. Where a defect straddles the two, responsibility becomes a question of drafting rather than fact. Read the contract to see whether the yard remains your single point of contact for equipment claims, or whether it expects you to pursue manufacturers directly once the vessel is delivered.

Note too the extension mechanics: many warranties reset or extend the guarantee period on any component the yard repairs or replaces, so a defect rectified in month eleven can carry fresh cover of its own. Check whether that extension runs on the repaired part alone or on the whole system it belongs to, because the difference decides how much of the vessel is still protected as the original term expires.

What the warranty covers — and what it excludes

A warranty covers defects in the yard's materials and workmanship that manifest within the guarantee period. It does not cover everything that goes wrong on a new vessel, and the exclusions are where most disputes begin. The distinction the owner must hold onto is between a latent defect — faulty work or material that existed at delivery and only later revealed itself — and deterioration arising from use, environment or the owner's own operation.

• Typically covered: faulty workmanship, defective materials supplied by the yard, non-conforming work that departs from the specification, and failures caused by the yard's design where design responsibility sat with the builder.
• Typically excluded: fair wear and tear, consumables, corrosion from normal exposure, damage from grounding, collision or misuse, and any modification carried out by third parties after delivery.
• Owner-caused voids: failure to follow the maintenance schedule, running equipment outside its rated parameters, or using a non-approved yard for interim work can all discharge the guarantee on the affected system.
• Grey zones: gelcoat crazing, teak movement, veneer lifting and paint defects, where the line between a build fault and normal settling is genuinely arguable.

Because the exclusions carry the money, the owner's team should map every reported issue to a category on the day it appears, with evidence, rather than arguing the taxonomy months later.

The snag list and the defect-notification process

The warranty is only as strong as the process that feeds it, and that process is procedural to the point of pedantry. At delivery, the owner's representative and the yard agree a snag list — the punch list of outstanding items visible at handover, which the yard commits to close within a defined window. Anything not captured there does not vanish, but it must instead travel through the formal defect-notification route the contract prescribes.

That route almost always requires written notice within a stated period of discovering a defect — often thirty days, sometimes less — describing the fault with enough particularity for the yard to investigate. Miss the notice window and the yard may reject an otherwise valid claim purely on procedure. The contract will usually also grant the yard the first right to inspect and, where it accepts liability, to carry out the remedy itself before the owner engages an outside contractor and bills back the cost.

Discipline here is decisive. Notify in writing, date everything, keep the fault available for inspection where practical, and never authorise a third-party repair on a warranty item without first giving the yard its contractual opportunity to attend — doing so is the fastest way to forfeit an otherwise sound claim. A single log, maintained by the owner's representative and shared with the yard, that records each defect, its notification date, the yard's response and the eventual remedy, keeps the whole guarantee period auditable and denies the yard the argument that notice was late or informal.

Retention funds and holdbacks

The most effective warranty enforcement tool is money the yard has not yet been paid. Well-negotiated build contracts hold back a retention — commonly a single-digit percentage of the contract price — released only after the guarantee period closes and outstanding defects are cleared. That retained sum, or an equivalent bank guarantee or parent-company guarantee standing in its place, is what gives the owner leverage that a purely contractual promise cannot.

The following comparison sets out how the common security mechanisms behave in practice.

The lesson is to fix the security at contract stage, not at delivery. An owner holding a meaningful retention rarely needs to fight; an owner who released every instalment on time has only the dispute clause left to rely on. Watch the release conditions as closely as the sum: a retention that falls away automatically at the guarantee period's end, regardless of open defects, is far weaker than one held until every notified item is closed to the owner's satisfaction. Where the yard offers a bond in place of cash, read its call conditions before accepting — a conditional bond that pays only on an arbitral award is a very different instrument from an on-demand guarantee the owner can draw at will.

Defect versus wear: where disputes are won or lost

The central battleground of almost every warranty claim is a single question: is this a defect the yard must remedy, or wear the owner must absorb? Yards have a commercial incentive to characterise problems as operational; owners see a vessel that should not be failing this soon. The answer is rarely settled by assertion — it is settled by evidence, expertise and the wording of the specification.

The specification is the anchor. Where the contract defined a standard, a material or a performance figure, a shortfall against it is a defect regardless of how the yard labels it. Where the specification is silent, the argument turns to what is reasonable for a vessel of that class and price, and that is where independent surveyors and marine engineers earn their fee. A credible expert report, prepared early and to a standard a tribunal would respect, frequently resolves the matter before it hardens into formal dispute. The owner who commissions such a report at first sign of trouble negotiates from a far stronger position than one who waits, because contemporaneous evidence of the defect's condition cannot be reconstructed later once a repair has erased it. Photograph and document before anything is disturbed, and where the fault is recurring rather than one-off, record the pattern — a defect that returns after each attempted fix is powerful evidence of a build fault rather than wear, and tribunals weigh such a history heavily when the specification alone does not decide the point.

Remedy, damages and the arbitration clause

When a claim is accepted, the contract usually gives the yard the right to remedy — to repair or replace the defective work — rather than simply pay the owner its cost. This is deliberate and generally favours the yard, which would rather send its own labour than write a cheque. The owner's leverage lies in the fallback: if the yard fails or refuses to remedy within a reasonable time, the contract typically permits the owner to engage others and recover the reasonable cost, which is precisely where a retention fund proves its worth.

Damages beyond the cost of repair — loss of use, a spoiled charter season, consequential loss — are usually excluded or tightly capped, so owners should not assume the warranty makes them whole for a ruined summer. Read the limitation-of-liability clause as carefully as the warranty itself.

Finally, the dispute-resolution clause governs everything. Superyacht contracts commonly refer disputes to arbitration — frequently London arbitration, or a MYBA-style mechanism — rather than the courts, chosen for confidentiality and marine expertise. Know your seat, your governing law and your notice deadlines before a defect ever appears, because the day a dispute crystallises is the wrong day to discover them.
