The correct answer is B) reduce your drift rate. Using a sea anchor will help reduce the drift rate of a liferaft or vessel. A sea anchor creates drag and resistance in the water, which slows down the drifting motion and keeps the vessel or liferaft more stationary. This can be crucial in survival situations to conserve resources and maintain position. The other answer choices are incorrect because: A) a sea anchor does not directly aid in recovering the liferaft, C) it does not increase visibility, and D) it does not specifically keep the liferaft from turning over, though it can help stabilize the raft's motion.
