Under Way refers to a vessel that is not at anchor, not made fast to the shore, or not aground, and is moving through the water.

Definition: A term used to indicate that a ship is in motion.

Usage:

Maritime Context: “The ship is under way and will reach the port in two days.”

Legal and Operational Implications: A vessel under way is subject to different rules and regulations compared to one that is anchored or moored.

Distinction from “Making Way”:

Under Way: Simply means the vessel is not stationary; it could be drifting or moving under its own power.

Making Way: Specifically means the vessel is moving through the water under its own propulsion.
