The COASTAL DRILLER, with a draft of 10 feet...

🔍 Key Concepts

• Displacement is the vessel’s weight, taken from the hydrostatic (draft–displacement) curves or table for the specific ship • You must use the exact draft in seawater (including inches) and interpolate if it falls between two tabulated drafts • Watch the units carefully: long tons vs kips (1 kip = 1,000 pounds)

💭 Think About

• From the stability booklet or hydrostatic tables, what displacement corresponds to a draft closest to 10 feet 3 inches in seawater? • If the tables only give whole‑foot or half‑foot drafts, how would you linearly interpolate between the two closest drafts to find the displacement at 10 feet 3 inches? • Once you have the displacement in long tons or pounds, how do you convert it correctly into kips and compare it with the answer choices?

✅ Before You Answer

• Be sure you are using seawater tables, not freshwater, for the displacement value • Confirm whether the base unit in the table is long tons or pounds, and convert correctly to kips • Double‑check your interpolation math and final unit conversion before matching with the nearest multiple‑choice option
