Laycan
The window of dates within which a ship must arrive and be ready to load, or the charterer may cancel.
Laycan is a contraction of "laydays / cancelling". It defines the earliest date the charterer must start counting laytime (laydays) and the latest date by which the ship must present and tender notice of readiness, failing which the charterer can cancel (the cancelling date).
A tight laycan raises positioning risk for the owner; a missed cancelling date lets the charterer walk away even if the market has moved against them. Laycan is one of the first items agreed in any fixture.
Also known as: laydays, cancelling date, lay/can.
