Under what conditions is yoke maintained?

Yoke is a specific status of readiness for a ship, primarily related to damage control and the management of watertight integrity. It is maintained during peacetime and when the vessel is in port to ensure that the crew can quickly respond to any potential emergencies or incidents.

This readiness allows for the swift closing of specific watertight doors and hatches, ensuring that the ship maintains its structure against potential flooding or fire hazards, even while at ease. In peacetime, the risks are generally lower, but maintaining yoke conditions is a proactive measure against unexpected emergencies.

The other options imply conditions that are either too extreme or misrepresent the purpose of yoke. In wartime scenarios, particularly when under attack, additional measures like "smart downtime" may be implemented, which typically calls for more stringent damage control protocols than what is typically classified as yoke. Likewise, the idea of maintaining yoke strictly at sea disregards the essential principle of maintaining readiness even when the ship is docked and ostensibly safe.
