🔍 Key Concepts

• Use the white pages of the Stability Data Reference Book for each tank’s vertical center of gravity (KG), not the diagram pages. • Remember that the overall KG of several liquids is a weighted average: total moments divided by total weight. • Be careful with port and starboard tanks listed separately or as P/S – confirm whether the weight shown is per tank or combined before calculating moments.

💭 Think About

• How do you use the KG value for each tank in the white pages to form a moment for that tank? What do you do with all those moments? • When you look up a DB tank (e.g., DB 4 CL), what specific column in the white pages gives you the vertical position you need, and how is it labeled? • If a tank is listed as DB 2 P and DB 2 S with the same weight, what happens to the KG of the combined pair when you add them together?

✅ Before You Answer

• For every tank in the table, make sure you have: weight, KG from the book, and moment = weight × KG. • After summing all tank weights and all moments, verify that you compute KG = (Σ moments) ÷ (Σ weights) and that your units are long tons-feet divided by long tons. • Double-check any entry written as P/S to be sure you are not accidentally doubling or halving that weight incorrectly.
