A man was sighted as he fell overboard. After completing a Williamson turn, the man is not sighted. What type of search should be conducted?

🔍 Key Concepts

• Man overboard (MOB) recovery procedures used by small vessels after a Williamson turn • Characteristics and best use of sector, expanding square/circle, and parallel track patterns in search and rescue (SAR) • How uncertainty in the casualty’s position (small vs larger area) affects which search pattern is chosen

💭 Think About

• Is the initial position of the man overboard known fairly well, or has it become very uncertain after the unsuccessful Williamson turn? • Which search pattern is normally used when you have a small, well-defined datum (last known position) and need to search that area very carefully? • Which patterns (from the choices) are more suited to larger areas or longer-duration searches rather than a tight, focused MOB search right around the last known point?

✅ Before You Answer

• Identify which option is specifically designed for searching around a single, reasonably well-known point (datum) • Eliminate any pattern that is primarily used for wide-area coverage instead of a focused local search • Verify which patterns are standard for man overboard searches when the person is lost from sight but the approximate position is still known
