The DEEP DRILLER, at a draft of 19 feet, has a KGL of 59.91 feet and an LCG of 1.57 feet. What is the trim angle?

Correct Answer: Option B — 0.3° by the stern

Longitudinal stability calculations utilize displacement, center of gravity (LCG), and longitudinal metacenter (LCM) relationships. Applying standard trim formulas (Trim = [LCG - LCB] * Displacement / MTC) yields the precise vessel trim angle of 0.3 degrees by the stern.
