By what method is the final light ship weight, longitudinal and vertical centers of gravity of a vessel, and final assignment of the load lines determined?

Correct Answer: Option C — By relying on resultant calculations from an inclining experiment.

An inclining experiment is the mandatory procedure required by 46 CFR to determine a vessel's lightship displacement and the vertical center of gravity (KG). By shifting known weights and measuring the resulting angle of heel, naval architects calculate the precise stability characteristics required for the vessel's stability booklet.
