🔍 Key Concepts

• LSA Code (Life-Saving Appliances Code) requirements for launching appliances and winch motors • Meaning of a motor’s short-time rating (how long it can run at full load without overheating) • Practical needs for repeated lifeboat launching and recovery during an emergency or drill

💭 Think About

• Ask yourself: In an emergency, for how long might the davit winch realistically need to run continuously to lower, recover, or re-launch the lifeboat? • Which option actually looks like a time in hours that could be a motor rating, rather than a date or a catalog/part number? • Think about why regulations specify a minimum operating period for critical life‑saving equipment—what duration makes sense to ensure safety but still be realistic for motor design?

✅ Before You Answer

• Identify which choice clearly represents hours of operation (a simple time value), not a date or code. • Recall from your LSA/SOLAS study materials the required minimum short-time rating for electric lifeboat winch motors (measured in hours). • Confirm that your selected option could reasonably correspond to that regulatory minimum operating period.
