You are scheduled to load 3900 tons of cargo, 45 tons of crew effects and stores and 259 tons of fuel. Use the blue pages of the Stability Data Reference Book to determine the vessel's mean draft in fresh water.

🔍 Key Concepts

• Use the blue pages hydrostatic data for this specific vessel (displacement vs. draft) • Total vessel displacement = lightship + cargo + crew effects/stores + fuel • Apply the salt water to fresh water draft correction if the blue pages are for salt water

💭 Think About

• First, find the vessel’s lightship displacement in the blue pages and add all given weights to get the new displacement. What is that number? • Once you have the total displacement, which hydrostatic table or curve in the blue pages lets you read or interpolate the corresponding mean draft? • If the tables are in salt water, how does the change in water density affect the draft, and how do you correct the draft for fresh water?

✅ Before You Answer

• Be sure you have included all weights: cargo, crew effects/stores, and fuel in addition to lightship • Verify whether the draft you read from the blue pages is salt water or fresh water and correct if necessary • Double-check any interpolation between tabulated displacement values to avoid simple math slips
