Audio Overview Chapter 3 Part 3 The_GG'_Formula

from Stability & Trim for the Ship's Officer Hosted by William E. George

Chapter 3, Part 3: The GG' Method and predicting changes in KG. Focus on the GG' formula: GG' = (w * d) / Final Displacement. Include a step-by-step, mathematically correct numerical example of loading or shifting weight to predict the vertical shift of G. Detail the three laws of G-movement: G moves directly toward a loaded weight, directly away from a discharged weight, and parallel to a shifted weight. Explain that a suspended weight acts at its point of suspension from the moment it is loaded. Conclude by emphasizing that the ship's actual drafts are the ultimate verification of stability math—'the vessel does not lie'.
