This represents the lowest extremity of the moulded surface of the ship. At the point where this line cuts the midship section a horizontal line is drawn, and it is this line which acts as the datum, or base line, for all hydrostatic calculations. This line may, or may not, be parallel to the LWL depending on the type of ship.
Le nto ibonakalisa incam esezantsi yendawo emxinwa enqanaweni. Kwindawo apho lo mgca unqumle khona indawo esembindini wenqanawe iyabonakala, kwaye ngumgca osebenza njengesiseko, okanye umgca osisiseko, kuzo zonke izibalo zezimanzisi. Lo mgca unganxusana okanye unganxusani neLWL kuxhomekeka kuhlobo lwenqanawe.
