🔍 Key Concepts

• Salt water vs. fresh water density and how this affects a vessel’s draft • The idea that a vessel’s displacement stays the same when moving between waters • The standard specific gravities often used in problems: 1.025 for seawater and 1.000 for fresh water

💭 Think About

• When a vessel goes from denser water to less dense water, does it float deeper or shallower? Why? • How can you use the ratio of densities (or specific gravities) to adjust the original seawater draft to find the new freshwater draft? • Which answer choice reflects a realistic change in draft for a 19‑foot seawater draft when switching to fresh water?

✅ Before You Answer

• Confirm you are using seawater ≈ 1.025 and fresh water = 1.000 in your calculation • Make sure you keep displacement constant and only change draft according to the change in water density • Check that your final draft is slightly deeper than 19 feet, not dramatically larger, and matches one of the options
