Question 68 ONC05 - Master or Mate of LT 200 GRT

The Correct Answer is D **Why Option D is Correct:** When a helicopter is lifting personnel from an enclosed lifeboat (or any small vessel), maintaining the stability of the boat is paramount. The powerful downdraft (rotor wash) from the helicopter creates significant instability, buffeting the boat and potentially causing it to capsize or swing violently, endangering the operation and the person being lifted. By having the remaining individuals remain seated inside the boat, they keep their body weight concentrated low and central, which maximizes the boat's stability and resistance to the external forces, thus providing a safer platform for the hoisting operation. **Why Other Options Are Incorrect:** * **A) Stand on the outside of the boat to assist the person being lifted:** Standing up or moving to the outside greatly raises the center of gravity of the boat, significantly decreasing stability and making the boat highly susceptible to capsizing due to the helicopter's downdraft and movement. Furthermore, the outside of the boat is dangerous during hoisting operations. * **B) Remove their life preservers to prepare for their transfer to the helicopter:** Life preservers must be worn at all times during a rescue operation. Removing them increases the risk of drowning if the boat capsizes or if they accidentally enter the water. Personnel should only remove essential safety gear under direct instruction from the helicopter crew or rescue personnel. * **C) Enter the water in case the person being lifted slips from the sling:** Entering the water unnecessarily puts the remaining individuals at extreme risk (hypothermia, injury from rotor wash, danger near the boat/hoist line) and removes essential stability weight from the lifeboat. Rescue efforts are complicated and rarely involve personnel voluntarily entering the water unless the vessel is sinking or capsized.
