In international voyage chartering, the negotiation of laytime is often a brutal war of attrition. Charterers fight for maximum laydays to insulate themselves from port bottlenecks, while Shipowners push for tight, aggressive loading and discharging windows to maximize their vessel’s daily yield.

When negotiations hit an absolute deadlock—especially in ports notorious for erratic infrastructure, seasonal congestion, or primitive lighterage operations—desks frequently deploy a seemingly magical compromise: Customary Quick Despatch (CQD).

To an uninitiated trading desk or an ambitious commodity shipper, CQD looks like the ultimate insurance policy. Because the contract completely deletes a fixed number of laydays or specified metric tonnes per day, the immediate threat of paying $30,000 per day in demurrage appears to vanish.

However, under English commercial law, CQD is not a free pass to delay a vessel indefinitely. It is a highly deceptive legal mirage. When a severe port disruption hits, treating CQD as a blanket liability shield is the fastest way to land your desk in an expensive London maritime arbitration.

The Legal Reality: The Elasticity of ‘Customary’

Under definitive English maritime precedents (such as Postlethwaite v. Freeland [1880] and The Helle Skou [1976]), fixing a cargo on CQD terms completely alters the legal mechanics of time counting:

1. The Deletion of Fixed Laytime: There is no fixed clock. The concepts of “Laytime” and “Demurrage” are technically extinguished from the charter party for the duration of that specific port operation.
2. The Implied Reasonable Obligation: In place of a fixed clock, the Charterer assumes a strict, implied obligation under common law to execute the cargo operations with “reasonable despatch” under the existing circumstances of the port.
3. The Customary Standard: “Reasonable despatch” is strictly measured against the customary methods, working hours, and ordinary equipment available at that specific terminal at that specific time.

  Delay is deemed customary.      Owner can sue for "Damages 
  No compensation for Owner.       for Detention" at market rate.

The Standoff: When the Infrastructure Breaks

The high-stakes friction occurs when a delay moves from a generic port slow-down to an infrastructure failure.

Consider a vessel arriving at a congested West African or South American port on CQD terms. The port is hit by a sudden shore crane breakdown, severe swell, or a routine seasonal administrative backlog.

• The Charterer’s Shield: The Charterer argues that because the local cranes are broken, the “customary speed” of the port has effectively dropped to zero. They claim that they are working with reasonable despatch under the existing circumstances, meaning they owe the Owner absolutely nothing for the 25 days the vessel sits idle at anchorage.
• The Owner’s Sword: The Owner retaliates by looking for a breach of the contract of carriage. If the Owner can prove that the delay was not caused by the port’s baseline infrastructure, but rather by the Charterer’s failure to have the cargo physically ready at the pier, or by an uncustomary administrative error in the shipping documents, the CQD shield shatters.

The moment the CQD shield is pierced, the Charterer is no longer paying standard, pre-agreed contract demurrage. Instead, they face a claim for Damages for Detention. Under English law, damages for detention are calculated based on the actual market rate of the vessel at the time of the breach. If the spot market has rallied significantly since the fixture was signed, a Charterer relying on a CQD clause can suddenly find themselves facing an unhedged, multi-million-dollar damages claim that far exceeds standard contract demurrage bars.

How Marcenta Eradicates the CQD Blindspot

The irony of modern commodity trading is that operations desks accept CQD formatting because they are hyper-focused on reducing immediate freight rates, completely ignoring the fact that they are trading a predictable demurrage cap for an unpredictable, unhedged market liability.

At Marcenta, when we enforce our guiding principle of Where cargo meets the right vessel, we bring absolute structural clarity to port terms. If a port truly demands CQD conditions due to localized operational realities, we do not simply rely on a generic three-letter acronym. We explicitly define the boundaries of custom within the rider clauses.

We write specific, tailored caps on waiting times, clarify precisely what constitutes an infrastructure failure versus a cargo availability default, and insert independent verification mechanisms to ensure our trading and chartering clients are never caught off guard by a sudden shift from a quiet port stay to an aggressive detention claim. We bring forensic commercial precision to your terms so your supply chain capital is always insulated.
