🔍 Key Concepts

• Scope as the ratio of length of rode (chain/line) to water depth • Conversion of fathoms to feet (know how many feet are in one fathom) • Including the full depth of water when calculating total rode needed

💭 Think About

• First, convert the depth from fathoms to feet. What factor do you multiply by? • Once you know the depth in feet, how do you apply a scope of 5:1 to find the required length of chain? • After calculating the needed length, which choice is closest to that number and matches your exact calculation?

✅ Before You Answer

• Verify the feet-per-fathom conversion before doing any other math • Confirm that scope of 5 means 5 times the depth, not divided by 5 • Double-check your final multiplication step before comparing it to the answer choices
