🔍 Key Concepts

• Draft marks are in feet, with each number one foot apart vertically • On standard load line/draft marks, the bottom of the number represents that whole foot of draft • To find mean draft, you average the forward and aft drafts

💭 Think About

• First, convert the forward reading: if the water is 4 inches below the 11, where is that relative to the 10-foot mark? • Next, convert the aft reading: if the water is 2 inches below the top of the 11, how many inches above the 11-foot line is it? • Once you have forward and aft drafts in feet and inches, how do you average two measurements to get the mean draft?

✅ Before You Answer

• Be clear whether you are measuring from the bottom of the numeral 11 or from its top when you interpret each statement • Remember that each foot is 12 inches, and the numerals themselves are typically 6 inches high • After averaging, make sure your final mean draft is between the forward and aft drafts and matches one of the choices in feet and inches
