If you shorten the scope of anchor cable, what is the effect of your anchor's holding power?

🔍 Key Concepts

• Scope of anchor cable/rode (ratio of length of cable paid out to water depth) • How horizontal pull vs. vertical pull on an anchor affects holding power • Effect of short vs. long scope on how the anchor lies on the bottom

💭 Think About

• Think about what happens to the angle of the cable at the anchor when you pay out more cable versus when you heave in cable. • Does an anchor hold better when it is pulled more horizontally along the bottom, or more vertically upward from the bottom? • Which change in scope would tend to make the pull on the anchor shank more vertical, and how would that affect its grip?

✅ Before You Answer

• Be clear on the definition of scope = length of cable ÷ water depth. • Visualize the angle of the cable at the seabed when scope is long compared to when scope is short. • Decide whether a more horizontal or more vertical pull gives better holding, then see which choice matches that effect.

If you shorten the scope of anchor cable, what is the effect of your anchor's holding power?

Holding power has no relation to scope

The holding power decreases

The holding power remains the same

The holding power increases
