Laycan

What is laycan?

Laycan is shorthand for laydays and cancelling: the range of dates within which the vessel must arrive at the load port and tender a valid notice of readiness. The laydays date is the earliest the charterer is obliged to accept the ship; the cancelling date is the last. Miss it and the charterer may cancel.

The two dates do separate jobs, and keeping them apart is the whole point of the clause. The laydays first date (sometimes written “laydays not before”) protects the charterer from a vessel arriving before the cargo is ready: the charterer does not have to commence laytime, or even accept the ship, before that date. The cancelling date (the “cancelling” half of laycan) protects the charterer from an owner who cannot deliver tonnage in time: if the vessel is not in load-port readiness by that date, the charterer has the option to walk away from the fixture. Between the two sits the laycan window, the band of days inside which both sides expect the ship to present.

Laycan is one of the four or five headline terms negotiated on any voyage charter fixture, alongside freight rate, the loading and discharge rate, demurrage and dispatch. It is the term that synchronises the ship’s position with the cargo’s availability, so it is fixed early in the negotiation and it shapes almost everything that follows: when the notice of readiness can validly be tendered, when laytime can begin, and whether the fixture survives a late vessel at all.

Reading the laydays and cancelling timeline

The laycan clause is best read as a short timeline. The dates run in a fixed order, and each one switches on a different right or obligation. The sequence below is the spine of every laycan provision.

1. 01

   Laydays first date

   Window opens

   The earliest date the charterer is obliged to accept the vessel and allow the notice of readiness to take effect. A ship arriving before this date cannot force laytime to begin.

2. 02

   The window runs

   Spread

   Between the first and last dates the vessel is expected to arrive at the load port and tender a valid notice of readiness. This is the laycan spread the parties agreed at fixing.

3. 03

   Cancelling date

   Window closes

   The last date by which the vessel must be in load-port readiness, having arrived and tendered a valid notice of readiness. This is the deadline that anchors the charterer's option.

4. 04

   The cancelling option

   Option

   If the vessel is not in load-port readiness by the cancelling date, the charterer may cancel the fixture. The option is the charterer's alone, and it must be exercised, not assumed.

5. 05

   Notice and narrowing of laycan

   Optional

   Where the clause allows, the owner gives definite notice of the vessel's expected arrival and the parties narrow a wide laycan to a tighter spread as the date approaches.

Two features of this timeline trip people up. First, the cancelling date is a deadline for readiness, not merely for arrival: a ship that has reached the port but cannot tender a valid notice of readiness, because it is not physically or legally ready to load, has not met the cancelling date. Second, the right at the end of the timeline is an option, not an automatic termination. If the vessel is late, the fixture does not cancel itself. The charterer chooses whether to cancel or to take the late ship, and many will take it if the market has moved in their favour.

Choosing a laycan window: narrow versus wide

The width of the laycan window is a negotiated trade-off, not a default. A narrow window of two or three days pins the ship to a tight arrival band; a wide window of a week or more gives the owner room to position. Each side of the fixture pulls in a different direction, and the right answer depends on the ballast leg, the market and how ready the cargo is. The decision matrix below sets out the trade-off across the dimensions that actually move the negotiation.

The selection criteria fall out of the matrix once you read it from each side. A narrow window is the right choice when arrival certainty is worth more than scheduling latitude: the charterer has a fixed terminal slot, a back-to-back sales obligation, or a downstream contract of affreightment nomination that depends on the ship presenting on a known date, and there is a prompt vessel close enough to the load area to hit the band without straining the ballast leg. In that situation the charterer accepts the freight premium because the cost of an out-of-window ship, a missed slot or a defaulted sale, is far larger.

A wide window is the right choice when the owner’s ability to deliver on time is the real risk: a long ballast leg, a volatile freight market where the owner wants to keep options open, or a prior-port turnaround that cannot be predicted to the day. Here the owner needs the spread to absorb slippage, and the charterer, whose cargo readiness is not yet pinned down, can afford to give it because a wider window also lowers the charterer’s own cargo-readiness exposure. The freight rate often moves a touch in the owner’s favour to reflect the scheduling latitude. The two criteria are mirror images: narrow buys arrival certainty at a freight premium and concentrates cancellation risk on the owner; wide buys positioning latitude at a freight concession and spreads the timing risk across the window.

How laycan connects to the laytime regime

Laycan does not stand alone. It is the front gate of the laytime regime, and several adjacent terms depend on it directly. The dependency map below shows the connected terms and exactly how each one bears on laycan.

Related term	How it connects to laycan	Page
Notice of readiness	A notice of readiness cannot validly be tendered before the laydays first date. An NOR given too early may be a nullity, so the laydays date gates the very document that starts the laytime clock.	Notice of readiness
Laytime	Laytime starts to count only after the vessel arrives within the window and a valid NOR is tendered (plus any turn time). Laycan opens the gate; laytime is what runs once the ship is through it.	Laytime
Demurrage	A cancelled fixture ends the owner's demurrage exposure before any laytime question arises. A tight laycan raises late-arrival risk, which in turn shapes how aggressively each side prices demurrage at fixing.	Demurrage
Dispatch	Because laycan fixes when the ship can present, it sets the earliest point from which time saved against laytime, and therefore any dispatch rebate, can begin to accrue.	Dispatch
Loading and discharge rate	The agreed cargo-handling rate sets how much laytime is allowed once the ship is in the window; laycan governs whether and when the ship gets there to start consuming it.	Loading and discharge rate

Read in order, the chain runs: the vessel must arrive inside the laycan window and tender a valid notice of readiness (which cannot be tendered before laydays open); turn time expires; laytime then counts at the agreed loading and discharge rate; and only when that allowance is exhausted does demurrage run, or dispatch become payable if the cargo finishes early. If the ship misses the cancelling date and the charterer cancels, the chain never starts: there is no NOR, no laytime and no demurrage to argue about.

How a laycan and cancelling clause is worded

Laycan on a dry-bulk fixture is usually carried on a GENCON-family template (BIMCO’s GENCON voyage charter form), with the dates filled into the boxes and a separate cancelling clause spelling out the option. A representative clause and its component parts read as follows.

The exact wording matters because it decides three things: whether the cancelling deadline turns on readiness or merely on arrival, whether the owner can compel an early decision from the charterer, and on what terms a wide laycan can be narrowed as the arrival date firms up.

Worked scenarios: declaring laydays and exercising the cancelling option

The matrix above resolves into concrete decisions only against a real position and a real market. The two anonymised scenarios below trace the same trade-off to opposite conclusions.

Scenario A: long ballast leg, volatile market. An owner is fixing a Capesize to lift iron ore, but the ship is completing a prior discharge several weeks of steaming away, and the freight market is moving sharply day to day. Running the matrix, the owner’s positioning flexibility is the binding constraint and cancellation risk is the danger to manage: a narrow window would leave no margin for a weather delay or a slow prior-port turnaround, and a missed cancelling date in a firm market hands the charterer a costless exit just as rates rise. The owner therefore pushes for a wide laycan, accepting a small freight concession for the spread. The charterer, whose stockpile is not yet fully built, can give the wider window because it also lowers its own cargo-readiness risk. As the ballast leg progresses and the arrival date firms up, the owner gives notice under the interpellation clause and the parties narrow the laycan to a tight three-day spread, converting the early flexibility into late certainty for both sides.

Scenario B: prompt vessel already in the load area. A charterer needs to load coal on a Panamax against a fixed terminal slot and a back-to-back sales contract with a hard delivery date. There is a prompt vessel already idle in the load area. Reading the matrix from the charterer’s side, cargo-readiness risk and arrival certainty dominate: an out-of-window ship would miss the terminal slot and put the sales contract in default, a cost far larger than any freight premium. The charterer therefore insists on a narrow two-day laycan and accepts the premium the owner prices in. Because the vessel is already in the area, the owner can meet the tight band without straining a ballast leg, so the cancellation risk that made a narrow window dangerous in Scenario A is largely absent here. The ship presents inside the window, tenders a valid notice of readiness, and the charterer never needs to consider the cancelling option at all.

The contrast is the lesson: the same clause mechanism, read through the same matrix, produces a wide window in a volatile long-ballast fixture and a narrow window in a prompt local one, because the binding risk is the owner’s positioning in the first case and the charterer’s cargo readiness in the second.

Scope and what this page does not cover

This page explains laycan as a commercial and charter-party concept: what laydays and cancelling mean, how to read the timeline, how to choose between a narrow and a wide window, how laycan feeds the wider laytime regime, and how the clause is worded. It does not draft jurisdiction-specific laycan or cancelling clauses, opine on whether a particular notice of readiness was validly tendered, decide whether a given vessel met the cancelling date on the facts, or advise on the consequences of a wrongful cancellation under a particular law and forum. Those questions are matters for chartering counsel and the desk’s operations team, working from the actual charter party, the master’s notice of readiness and the statement of facts. Market-volatility framing here is general and should be checked against current Baltic Exchange route assessments; the worked scenarios are representative and anonymised, not market quotes.
