🔍 Key Concepts

• How to read drafts correctly in feet and inches from the Stability Data Reference Book tables • Relationship between mean draft and the tabulated MT1 values in the blue pages • How to properly interpolate between two MT1 values if your exact mean draft is not listed

💭 Think About

• What is your forward draft and after draft converted into decimal feet, and what is the mean draft based on these? • Once you find the closest two mean drafts in the blue pages that bracket your actual mean draft, how do you determine whether the correct MT1 should be closer to the lower or higher tabulated value? • If interpolation is needed, how big is the change in MT1 between the two surrounding drafts, and what fraction of that change corresponds to the difference between your mean draft and the nearest tabulated draft?

✅ Before You Answer

• Make sure drafts like 16'-02" and 20'-08" are converted into decimal feet correctly before averaging • Confirm that you are using the correct vessel and displacement condition table in the blue pages • Double-check any interpolation calculation: change in draft, change in MT1 per foot, and the fraction applied to get your final MT1
