Question 1 of 27070

🔍 Key Concepts

• Catenary moorings and how weight per foot affects the curve of the line on the seabed • Difference between chain and wire rope behavior under load (stretch, stiffness, and bottom contact) • How holding power is created by friction on the bottom versus the strength of the line itself

💭 Think About

• Think about which material, at the stated weights, will tend to lie on the bottom more and create a longer contact patch with the seabed for the same tension and depth • Ask yourself whether holding power in this context is mainly limited by the line’s breaking strength, or by how well the mooring resists dragging along the bottom • Compare what happens to the shape of a heavy chain versus a lighter wire rope under the same horizontal load from wind/current

✅ Before You Answer

• Confirm that holding power here refers to resistance to dragging the anchor/mooring, not just line tensile strength • Check which line type (at the given weights) will have more weight in the water and on the bottom per foot • Verify how a heavier catenary (per foot) changes the angle of pull at the anchor or mooring point for the same tension
