Sailing on or about是什麼意思

"Sailing on or about" is a term commonly used in nautical contexts, particularly in the context of scheduling and planning. Here's what it means:

• "Sailing on" typically refers to a specific date or time when a ship is scheduled to depart from a port. This could be the exact date and time or a planned departure window.

• "Sailing about" or "sailing around" might refer to a period of time during which a ship is expected to be in a certain area or to make a specific journey. It suggests a less precise timing than "sailing on," indicating that the ship's movements might be somewhat flexible or subject to change based on weather, sea conditions, or other factors.

In the context of a sailing schedule or a maritime itinerary, "sailing on or about" would mean that the ship is scheduled to sail on a certain date, but there is some flexibility built into the schedule. This allows for adjustments to be made if necessary without necessarily changing the planned departure date.

For example, a sailing schedule might read: "The vessel is scheduled to sail on or about July 15th." This means that the ship is expected to depart on July 15th, but the actual departure could be a day or two before or after that date, depending on operational considerations.

This term is useful in maritime operations because it allows for some flexibility in scheduling without creating the impression that the departure date is completely open-ended. It's a way of indicating that there is a planned departure time frame without specifying exact details.
