🔍 Key Concepts

• TPC (Tons Per Centimeter Immersion) and how it relates to change in draft • Using waterplane area with the waterplane coefficient to find immersed area • Unit conversions between feet, inches, centimeters, and long tons

💭 Think About

• How can you use the ship’s length, beam, and waterplane coefficient to estimate the waterplane area? • Once you know the waterplane area, what formula connects a small change in draft with the weight added to the vessel? • Are you working entirely in a consistent set of units (feet vs. meters, inches vs. centimeters, long tons vs. pounds)?

✅ Before You Answer

• Be sure to convert the 1 inch change of draft into the correct unit for the formula you use (often centimeters or meters). • Confirm you’ve correctly applied the waterplane coefficient (Cw = 0.84) to the product of length × beam to get the effective waterplane area. • Double-check that your final answer is in long tons, not in pounds or metric tonnes.
