🔍 Key Concepts

• draft observations at bow and stern on a vessel • difference between observed drafts and calculated drafts • the meaning of center of flotation

💭 Think About

• Ask yourself: when you physically read the draft marks on the hull, what do you call the simple average of those readings? • Which answer choices introduce extra words (like 'true' or 'calculated') that might suggest an additional correction has been applied to the raw observations? • Is the center of flotation a point related to where the ship trims and floats, or a term for an average of readings?

✅ Before You Answer

• Identify which option refers directly to observed (raw) readings with no extra corrections. • Eliminate any choice that clearly involves calculated or adjusted values instead of simple observations. • Confirm that center of flotation is a geometric/physical point of the ship, not a statistical average of multiple readings.
