Example Formula. The primary formula used to calculate the displacement of a ship is based on its physical dimensions and block coefficient. The block coefficient is a dimensionless number that describes how closely the shape of a ship resembles a rectangular block.
27 kwi 2018 · That´s the formula to calculate your D/L-ratio. The formula is as easy as ABC: Displacement (pounds) divided by 2.240 and then divided by the length of the waterline in feet cubed multiplied by 0,01.
The prismatic coefficient is the ratio of actual underbody volume to the volume of a prism having a length equal to the DWL, and a section equal to the boat's maximum sectional area. The prismatic coefficient provides an indication of the distribution of displacement.
28 kwi 2010 · The complete formula is as follows: D/L = DLT ÷ (0.01 x LWL)³. As an example, to find the D/L ratio of a 12,000-pound boat with a load waterline length of 28 feet, you first divide 12,000 by 2,240 to find the boat’s displacement in long tons: 12,000 ÷ 2,240 = 5.36 long tons.

17 paź 2019 · The displacement to length ratio of a boat is a good comparing parameter for most boats. It is usually referred to sailing boats and it is also seen with the symbol D/L . Basically it shows how heavy the boat is in comparison to the waterline length.
The displacement–length ratio (DLR or D/L ratio) is a calculation used to express how heavy a boat is relative to its waterline length. DLR was first published in Taylor, David W. (1910). The Speed and Power of Ships: A Manual of Marine Propulsion. John Wiley & Sons. p. 99.
