What is the displacement of the DEEP DRILLER...

🔍 Key Concepts

• Fresh water vs. salt water displacement (1 long ton = 35 cubic feet of seawater; fresh water is slightly less dense) • How draft relates to underwater volume and displacement on a hydrostatic or draft–displacement curve • Using interpolation when draft does not fall exactly on a table value

💭 Think About

• If the DEEP DRILLER’s draft is 19.5 feet, how would you find the corresponding displacement on a draft–displacement curve or hydrostatic table? • If the table only gives displacement for whole-foot drafts (for example 19 ft and 20 ft), how can you estimate the displacement at 19.5 ft? • How would the displacement differ, if at all, between fresh water and salt water for the same draft, and is that already built into your data?

✅ Before You Answer

• Confirm whether the hydrostatic data you’re using are labeled for fresh water or salt water and stay consistent • Make sure you use the correct units (feet for draft, long tons for displacement) and don’t mix metric and imperial • If you interpolate between two values, carefully check the difference per 0.1 or 0.5 ft of draft so you don’t mis-read the table or mis-scale the change
