The TPI curve, one of the hydrostatic curves in a vessel's plans, gives the number of tons __________.

🔍 Key Concepts

• Hydrostatic curves and what they describe for a vessel at a given draft • Meaning of TPI (tons per inch immersion) versus trim or list corrections • Difference between changing overall immersion, trim, and list

💭 Think About

• Ask yourself: Does TPI deal with how the ship sits deeper uniformly in the water, or how it pivots by the bow or stern? • Which quantity would be affected if you add weight evenly across the ship so it stays level—does that change trim, list, or immersion? • Which of the options mentions a unit that naturally matches the name "Tons Per Inch"?

✅ Before You Answer

• Make sure you know that trim is the difference in draft forward and aft, while list is the angle of lean to one side. • Check which choice clearly relates tons of weight to an inch change in draft rather than angle or pressure. • Verify that TPI is used when calculating how much weight will make the vessel sit deeper all around at a given draft.
