Q

The "trimming arm" of a vessel is the horizontal distance between the __________.

🔍 Key Concepts

• Longitudinal center of gravity (LCG) and how it affects trim • The role of the longitudinal center of flotation (LCF) in trimming calculations • Difference between centers related to buoyancy (LCB) and flotation (LCF)

💭 Think About

• When a vessel trims (pitches bow up or bow down), around which longitudinal point does it effectively rotate? • Which two longitudinal points do you compare when calculating how much trimming moment a given weight will create? • Is trimming more directly related to the change in buoyant force location or to the pivot point of the waterplane? Think about standard trim formulas.

✅ Before You Answer

• Identify which abbreviation represents the pivot point for trim (about which the ship seesaw’s fore and aft). • Confirm which abbreviation represents the longitudinal position of the ship’s weight (where the total weight acts vertically down). • Eliminate any option that pairs two points not typically used together in standard trim-by-stern / trim-by-bow formulas.
