Logistics · Deadweight Tonnage Calc

Vessel displacement and deadweight estimate from hull dimensions: volume = length × beam × draught × block coefficient; displacement = volume × water density (sea 1.025, fresh 1.000 t/m³); deadweight = displacement − lightship weight (if given). Also returns the cargo capacity left after fuel, stores and ballast you enter. A design-stage estimate from standard formulas, not a vessel's official DWT; no ship registry lookup.
