What the examiner is really probing
The examiner is not checking whether you can describe a piece of machinery. They are checking whether you, as Master, have a functioning system ready to save the vessel if primary steering fails at sea. A pass-standard answer demonstrates that you own the testing regime, that your crew can execute the change-over without confusion, and that you understand your SOLAS obligations precisely — dates, intervals, records, and command authority.
The regulatory framework
SOLAS V/26 governs steering gear testing and drills. Two distinct obligations apply:
Pre-departure test (V/26.1): The main and auxiliary steering gear must be checked and tested within 12 hours before departure. This is a functional test — it confirms that everything moves, responds, and communicates correctly before the vessel leaves port.
Emergency steering drill (V/26.4): A drill involving direct control of the vessel from the steering gear compartment must be conducted at least every three months. This is a crew drill, not a mechanical check. It must include:
- Operation of the communications system between the bridge and the steering gear compartment
- Manned control from the steering gear compartment itself
- Activation of local steering, bypassing the bridge helm
All steering gear tests, checks, and drills must be recorded in the Official Log Book.
What an emergency steering system actually comprises
On a yacht, emergency steering typically means one or more of the following, depending on installation:
- Auxiliary steering gear: A second, independent power unit or pump engaging the same rudder stock
- Manual (mechanical) override: Tiller or lever directly on the rudder stock in the steering compartment
- Autopilot bypass / hand-steering fallback: Steering from a secondary helm station, if fitted and designated
- Emergency tiller: Required as a last resort on many vessels; must be capable of being shipped rapidly
As Master you must know the change-over procedure for each mode, and ensure your bridge watch officer and helmsman do too. If the procedure requires more than one person, that person must have been drilled.
Command considerations
When primary steering fails, your priorities are: warn traffic and the engine room, reduce speed to reduce steering loads, change over to auxiliary or emergency steering, and re-establish a safe course. The log must record the failure, the time of change-over, the action taken, and any communication with authorities.
How to structure your spoken answer in the exam
Lead with your regulatory obligation (V/26.1, 12 hours; V/26.4, three-monthly drill). Then describe what you actually test and drill — communication, local control, the people involved. Finish with your operational response should steering fail at sea. Speak as the person who owns the system, not someone describing it from a textbook.
