Q.3 ‘M.V.Hindship’ displacement 8473 MT, KG: 8.84m, FSC: 0.146m, is to be Dry-docked. At the critical instant the GM (f) of the vessel is to be not less than 0.20m. Determine the maximum trim by stern with which she will enter Dry-dock if she is to take to the blocks first at the AP. Also state the arrival dry-dock drafts
