What is displacement? In order to get an answer to this question, we turn to marine concepts.
Terminology
Displacement is the volume of water displaced by the ship. The weight of this fluid is the weight of the vessel. Therefore, displacement is usually measured in weight units - tons, and not in volume units - liters and gallons. The weight of the ship is a variable value, which varies depending on the fuel consumption and cargo load of the ship. Because the displacement of the vessel is divided into "full load" and launch. Consider each of the options. What is a “full load” displacement? This is the weight of the ship at full load. Launching weight means the weight of the vessel during launching, i.e. without equipment. If they ask what displacement is, then, in simple words, this is the weight of the vessel.
Displacement Measurement
Displacement of ships is measured at the design stage according to the theoretical drawing. How does this happen? Along the entire drawing length of the vessel, lines are drawn that divide the hull into 20 equal parts. Then, cross-sectional lines and waterline lines are drawn. Then they resort to the Simpson method in the same way as when calculating the capacity, converting the result from cubic feet to tons by dividing by 35 if the vessel is intended for navigation in salt water, or by 36 for fresh water.
