Question 3943 Deck General

The correct answer is D) prevent dragging of the anchor. Increasing the scope (length) of the anchor chain when anchored helps to prevent the anchor from dragging across the seabed. A longer scope allows the anchor to dig in more deeply and distribute the force of the vessel's movement over a larger area, reducing the likelihood of the anchor breaking free and the vessel drifting. The other options are incorrect - increasing scope does not directly prevent fouling of the anchor, reduce strain on the windlass, or decrease the vessel's swing. The scope of the anchor chain is a key factor in maintaining a secure anchoring position.
