What is the 'deadweight' moment, and how is it calculated in relation to ship trim?

The deadweight moment is the longitudinal moment created by the distribution of the ship's deadweight, which includes the weight of cargo, fuel, water, stores, and crew, relative to the ship's longitudinal center of flotation (LCF). Trim, the difference between the forward and aft drafts, is directly affected by this moment. To calculate the deadweight moment, each item of deadweight is multiplied by its longitudinal distance from the LCF. Weights locat....
