The DEEP DRILLER, at a draft of 60 feet, has a KGL of 55.4 feet and an LCG of 2.37 feet. What is the trim in feet?

Correct Answer: Option B — 4.0 feet by the head

Trim is calculated using longitudinal moments (LM) and longitudinal center of gravity (LCG) relative to the center of flotation. For the DEEP DRILLER at a 60-foot draft with the given KGL and LCG parameters, standard hydrostatic tables yield a trim of 4.0 feet by the head.
