🔍 Key Concepts

• How to read draft marks when the waterline falls between two numbers • Converting inches to feet and inches (remember 12 inches = 1 foot) • How to calculate mean draft from forward and aft drafts (average of the two)

💭 Think About

• What is the exact forward draft in feet and inches if the water is about 4 inches BELOW the top of the 11 mark? • What is the aft draft in feet and inches if the water is exactly at the top of the 10 mark? • Once you know both drafts, how do you find the mean (average) draft?

✅ Before You Answer

• Be sure you are measuring upward from the lower number to the waterline, not downward from the higher number • Confirm each draft is written as feet and inches before averaging • After averaging, check that the final value is between the forward and aft drafts you calculated
