For a vessel with a block coefficient of 1, the addition of weight at the center of flotation will __________.

🔍 Key Concepts

• Block coefficient of 1 and what it means about the underwater shape of the vessel • Definition of center of flotation (F) and how it relates to trim • Difference between change of trim and change of mean draft when weight is added

💭 Think About

• Visualize a perfectly rectangular barge (block coefficient = 1). If you add weight exactly at the center of flotation, will the vessel try to rotate (trim) or just sink bodily? • Ask yourself: does adding weight at the center of flotation create a trimming moment about that point? Why or why not? • Consider whether stability (GM) is automatically affected any time weight is added, or if the location of that weight matters.

✅ Before You Answer

• Confirm that center of flotation is the pivot point about which the vessel trims, not necessarily the center of gravity • Check whether a force acting through the pivot point can create a moment to cause trim • Separate in your mind the concepts of trim (difference between drafts forward and aft) and overall stability (tendency to return to upright after heeling) before choosing an option.
