358. Your vessel is on an even keel. The MT1 of your vessel is 1000 ft-tons. How many tons of cargo must be loaded in number 4 hold which is 100 feet abaft the tipping center, if she is to have a 2 foot drag?

The required cargo weight is calculated by equating the trimming moment from the added cargo to the moment needed to achieve the desired trim. The trimming moment is the product of the weight of the cargo and its distance from the tipping center, and the required trimming moment is the MT1 multiplied by the trim in inches. Therefore, a weight of 240 tons must be loaded in number 4 hold.
