In port, what signal at the dip on an approaching ship indicates it is preparing to come alongside?

When a ship displays the India signal flag at the dip, it indicates that the vessel is preparing to come alongside. This practice is part of the international maritime communication system, where specific flags carry distinct meanings for vessels at sea and in port.

The India flag specifically signals that the ship is either making preparations to moor or is planning to take on pilot services. By displaying this signal at the dip, it communicates to other vessels around that the ship is not yet ready to make the maneuver but is preparing to do so. This advanced notice is crucial for safety and coordination in a crowded port environment, helping to prevent accidents and ensure an orderly flow of traffic.

This signal is vital in maritime protocol, particularly in busy ports where multiple vessels may be maneuvering in close proximity to one another. Understanding the meanings of flag signals contributes to safer navigation and effective communication between ships and authorities in various maritime operations.
