Question 45 LB01 - Lifeboat Operator

The Correct Answer is A. **Why Option A is Correct:** Overturned liferafts are specifically designed with features to facilitate re-righting. The **righting strap** (or righting line/loop) is a heavy-duty strap located on the underside (now the top) of the inverted canopy/floor assembly. This strap is designed to allow a survivor to climb partly onto the craft. The **inflating cylinder** (or CO2 bottle/container, often stored in a pocket near the perimeter) provides a stable, weighty point that a person can stand on. By standing on the weight of the cylinder or inflation mechanism and simultaneously pulling the righting strap, the survivor applies leverage and shifts their body weight effectively to the side, leveraging the raft to flip back into its upright position (canopy up). **Why Other Options Are Incorrect:** * **B) Pushing up from under one end:** Liferafts, especially larger ones, are too large and buoyant to be easily flipped by pushing up from underneath by someone who is fully immersed in the water. The required leverage cannot be achieved effectively from below the water line. * **C) Filling the stabilizers on one side with water:** Stabilizers (water pockets or ballast bags) are designed to fill *automatically* once the raft is deployed and are used to stabilize the raft *in its upright position* by preventing lateral movement and reducing wind drift. Attempting to fill only one side of the inverted craft manually is impractical and not the designed method for re-righting. * **D) Releasing the CO2 cylinder will automatically upright the craft:** The CO2 cylinder is used for the initial inflation of the raft, which happens immediately upon deployment. Once the raft is fully inflated, the CO2 has been released. Releasing the CO2 (or attempting to release it again) would only deflate the craft, making it unstable or unusable, and would certainly not cause it to flip automatically.
