🔍 Key Concepts

• Trim: the difference between draft forward and draft aft at any moment • How loading or discharging weight changes a vessel’s drafts and therefore its trim • Distinguishing between a condition at a given time (initial/final) and the difference between two conditions

💭 Think About

• Ask yourself: which term describes the amount of change between the vessel’s trim before and after loading, not the trims themselves? • Look at each choice and decide: is this referring to a single condition (like before or after) or to the comparison between the two? • Think about standard stability/trim formulas: when you calculate how much the vessel’s trim has altered, what quantity are you actually computing?

✅ Before You Answer

• Identify which option explicitly refers to the difference between two trim conditions, not just one • Eliminate any choice that simply renames the vessel’s trim at one moment (initial or final) • Recall common stability terms used with KM, GM, TPC, MCT 1 cm/1 in and how they’re phrased when describing a change due to loading
