Question 38 LB01 - Lifeboat Operator

The Correct Answer is A. **Explanation for Option A (It reduces your drift rate):** The primary function of a sea anchor (or drogue) is to stabilize the survival craft by utilizing the drag created by the water. By deploying a large, submerged device that resists being pulled through the water, the sea anchor significantly slows the rate at which the raft or boat is pushed by the wind and surface currents. This reduction in drift rate is crucial for staying within a search area or reducing the distance the craft is moved away from a known position. **Why the other options are incorrect:** **B) It keeps the survival craft from turning over:** While the sea anchor does help stabilize the craft and keep the bow (or entrance) oriented toward oncoming waves, its primary mechanism is drag, not flotation or rigid stabilization. A survival craft's design (low center of gravity, ballast bags) is the main factor preventing it from turning over. **C) It increases your visibility:** A sea anchor is submerged and does not contribute to visibility. Visibility is increased by measures such as radar reflectors, EPIRBs, signal flares, and highly visible canopy colors. **D) Aids in recovering the survival craft:** The sea anchor is not designed as a recovery device. While slowing the drift rate (A) aids in *locating* the craft, the sea anchor itself must typically be pulled in or cut away to allow the rescue vessel to approach and recover the survivors or the craft.
