Laydays

​Laydays​​ (short for "Laydays and Cancelling Date") defines the timeframe within which a shipowner must position the vessel at the load/discharge port and formally declare its readiness via a ​​Notice of Readiness (NOR)​​. 

What is Laydays?

Key Components​

Notice of Readiness (NOR)​

A formal declaration by the shipowner that the vessel is physically and legally prepared to load/discharge.

Validity often hinges on contractual terms like WIBON ("Whether in Berth or Not") or WIFPON ("Whether in Free Pratique or Not").


Cancelling Clause​

If the vessel arrives late, the charterer may cancel the contract, re-charter another vessel, or negotiate revised terms.

The shipowner bears the risk of delays caused by unforeseen events (e.g., weather, mechanical issues).

 

Interpellation Mechanism​

If the shipowner anticipates missing the cancelling date, they must notify the charterer promptly.

The charterer then has 48 hours to accept a new ETA or cancel the contract.



Operational Importance​


Risk Allocation​​:
The Laydays clause balances accountability:

Shipowners must optimize voyage planning to meet the window.

Charterers must ensure cargo readiness to avoid delays and potential demurrage claims.


Commercial Flexibility​​:
Charterers may negotiate "overlapping" Laydays for multi-port operations or seasonal constraints (e.g., monsoons, ice conditions).


Legal Safeguards​​:
Disputes often arise over NOR validity or force majeure delays. Clear contractual language and documentation (e.g., logs, port records) are vital for arbitration.

 

Practical Considerations​

Port Readiness​​:

Physical readiness: The vessel must be within the port’s commercial zone (e.g., anchorage).

Legal readiness: Compliance with customs, health inspections, or security clearances.

 

Cargo-Specific Requirements​​:

For sensitive cargo (e.g., grain, oil), additional checks (e.g., tank cleanliness certifications) may delay NOR validity.

 

Economic Adjustments​​:

Shipowners may adjust sailing speeds to align with Laydays, avoiding early arrival penalties or fuel waste.
