Question 3403 Deck General

The correct answer is A) water depth. When piggybacking anchors, the distance between the primary and secondary anchors is determined by the water depth. The deeper the water, the more rode (anchor line) is required for the secondary anchor to effectively grip the bottom and provide additional holding power. This distance is typically calculated based on the water depth and the scope (ratio of rode length to water depth) needed for the type of anchor being used. The other factors like anchor types, bottom conditions, and winch capacity do not directly determine the distance between the primary and secondary anchors when piggybacking.
