The canceling date is the final layday and the date beyond which, if the chartered vessel has not been presented for loading, the charterers may not accept the ship and may cancel the charter. The terms of this pro- vision will usually be found in a canceling clause, which provides that the charterers will not be entitled to cancel the charter before the stated canceling date, even when it is obvious that the vessel cannot arrive at the loading port by this date. Laydays and canceling are often called the laycan; they represent the period within which the vessel must be presented at the agreed port or place. If the vessel arrives before the first day of the period, the charterers do not have to accept her until commencement of the agreed laydays. If she arrives after the final layday, the charterers are entitled to reject the vessel and cancel the charter. Laycan is a ship’s arrival window (the time between tendering NOR and the cancellation date and time provided for in the charter party). In The Front Commander (2006), Rix L. J. defined laycan as (a) the earliest day upon which an owner can expect his charterer to load; and (b) the latest day upon which the vessel can arrive at its appointed load- ing place without being at risk of being canceled. This window is very short, hence ships may arrive earlier to make sure that they are present within the laycan window.
