🔍 Key Concepts

• Relationship between forward and aft drafts and a vessel’s trim • How longitudinal center of gravity (LCG) location affects trim when there are no environmental forces • Sign convention: which direction (forward or aft) is considered positive for LCG/trim

💭 Think About

• First, compute the trim from the given forward and aft average drafts. Is the unit trimmed by the head or by the stern? • If the unit trims in that direction, where must the center of gravity lie relative to the longitudinal center (forward or aft)? • Compare the small vs. large answer choices: which magnitudes are reasonable for a small trim difference over the unit’s length?

✅ Before You Answer

• Verify which draft is greater (forward or aft) and what that says about trim direction • Be clear on the sign convention: is forward of the reference point taken as positive or negative? • Check whether the computed LCG shift should be a small correction or a large distance, and eliminate options whose magnitudes don’t match the small trim observed.
