314. Regulations require which action to be performed prior to the vessel departing on a voyage more than 48 hours long?

Regulations mandate testing the entire steering gear within 12 hours before departure for voyages exceeding 48 hours, as stipulated by SOLAS Chapter V and U.S. regulations (46 CFR). This requirement ensures critical control and maneuverability, unlike lifeboat drills, fire pump tests, or emergency generator tests, which have different scheduling requirements.
