How would a charterer calculate a laycan window?

• A. Take the day the terminal is ready and subtract transit time
• B. Add transit time to the day the terminal is ready
• C. Use a fixed calendar date without reference to readiness
• D. Calculate based on vessel speed only

Answer: (A)

Laycan window is set by tying the ship’s timing to the port’s readiness to load. You start from the date the terminal will be ready to receive cargo and back-calculate the ship’s arrival by subtracting the transit time needed to reach the port. This gives the earliest date the vessel should be in position to load. The window then ends on the terminal’s readiness date, since that’s the latest acceptable date to begin loading. This back-calculation ensures there’s enough time for the voyage to complete and for the ship to be ready when loading starts. It isn’t based on a fixed calendar date with no regard to readiness, nor is it determined by speed alone.
