🔍 Key Concepts

• Scope of an anchor rode is the ratio of the length of rode (cable/line) to the vertical distance from bow chock to seabed • Typical small-boat scope for anchoring in normal conditions is about 6:1 • You must convert the scope ratio and water depth (plus bow height if applicable) into total feet of anchor cable needed

💭 Think About

• If the scope is 6:1, what does the number 6 represent, and what does the 1 represent? • In this question, what measurement is the "1" side of the ratio referring to—what exact distance are you multiplying by 6? • Once you know the correct distance to use for the "1," how do you calculate the total length of cable from the given depth of water?

✅ Before You Answer

• Be sure you understand that scope = rode length : vertical distance (bow to bottom), not just random multiples • Check that your final length is greater than the depth of water (it will not be close to or less than 12 feet for a 6:1 scope) • After calculating, verify which choice is closest to your computed length without changing the scope ratio
