What signal configuration would indicate that a vessel is making way but is not under command?

The signal configuration that indicates a vessel is making way but is not under command is represented by the display of red over red lights along with sidelights. This configuration is important because it provides critical information about the status of the vessel to other mariners.

When a vessel is not under command, it means that it is unable to maneuver as required due to some limitation, and it may be in distress. However, if it is still making way, it communicates this status using the red over red lights. The addition of sidelights further clarifies its position and orientation, ensuring that other vessels can recognize its situation clearly, thereby maintaining safety on the water.

The other configurations reflect different situations. Red over white indicates a vessel that is restricted in its ability to maneuver, while green over white is typically used by trawlers or vessels engaged in fishing. Flashing red and white lights serve specific purposes in navigation and signaling emergencies but do not denote the same status as that of a vessel making way yet not under command.
