🔍 Key Concepts

• Mean draft – the average of the drafts forward and aft • The difference between Tons Per Inch (TPI) and Moment to Change Trim 1 inch (MT1) • How weight affects draft evenly (parallel sinkage) vs. differentially (trim)

💭 Think About

• Ask yourself: does the question talk about changing trim (difference between forward and aft drafts), or changing the overall mean draft evenly? • Which term is used when a weight is added or removed so the ship goes deeper or lighter uniformly without changing trim? • Look at the units: which option is defined in tons per inch of immersion rather than in terms of a trimming moment?

✅ Before You Answer

• Confirm whether the question mentions trim or only mean draft • Check which of the choices is a standard hydrostatic table value expressing tons needed per inch change in draft • Be sure not to confuse a trimming moment (in ton-feet or ton-meters) with a plain weight in tons.
