🔍 Key Concepts

• catenary mooring systems and how chain length affects holding power • the relationship between the angle of pull on an anchor and its tendency to drag or break out • why storms and heavy seas require a flatter lead on the anchor, not a steeper one

💭 Think About

• Think about how an anchor holds best: does it resist better when it is being pulled more horizontally along the bottom or more vertically upward? • In a storm, the vessel’s vertical motion (heave) increases. How does a longer mooring line help reduce the vertical component of the force at the anchor? • Imagine the chain lying on the seabed: which angle between the anchor shank and the ocean floor would keep more chain on the bottom and reduce the chance of tripping the anchor?

✅ Before You Answer

• Verify which choice gives the most horizontal pull along the seabed rather than lifting the anchor. • Eliminate any angles that would produce a large upward (vertical) force on the anchor shank in heavy weather. • Consider standard guidance for catenary anchors: the goal is to keep the lead to the anchor as flat as practicable in storms.
