It depends on the lightship draft and the hydrostatic curves also, You must have those things to estimate the draft with load ( assuming that it doesn't pitch)
If i want to load lets say 24135 MT of iron ore in a ship, how much draft will the ship has by the end of the loading operations? I have some information if needed: DWT: 43479.3 mt Summer Draft: 10.7 meters Deductible weights: 700 mt tpc: 54.7 Density of the water: 0.996 LOA: 189.99 LBP: 186.65 BREATH MOULDED: 30 Lightship: 10072.5
