You are scheduled to load 3700 tons of cargo, 45 tons of crew effects and stores and 427 tons of fuel. Use the blue pages of the Stability Data Reference Book to determine the vessel's mean draft in salt water.
• Deadweight = cargo + fuel + stores/crew effects added to the vessel’s lightship displacement • Using the blue pages (hydrostatic/displacement vs. draft table) of the Stability Data Reference Book • If the exact displacement isn’t listed, use interpolation between two drafts
• First, what total added weight (deadweight) are you putting on the vessel, and how does that combine with the vessel’s lightship to give you a final displacement? • Once you know the final displacement, where in the blue pages can you match (or bracket) that displacement to find the corresponding mean draft? • If your displacement falls between two table values, how do you proportion the difference to get a more accurate mean draft before choosing from the multiple‑choice answers?
• Be sure you are using salt water displacement data, not fresh water • Confirm you have included all three weights: cargo, crew effects/stores, and fuel • Double‑check that the final draft you select matches the displacement range you computed from the tables
