Understanding and calculating marine displacement is essential for the design and operation of ships. This tutorial delves into the formulas and calculations associated with marine displacement, focusing on length, breadth, draft, and block coefficient.
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.
The D/L ratio is the ratio between the displacement and the length of a boat. The calculation is very popular because its simplicity and the fact that the values of the displacement and the length are easily available.
The formula for calculating the Sail Area/Displacement Ratio is: SA/ (DISPL)0.67, where... SA is sail area in square feet, and. DISPL is boat displacement in cubic feet. Clearly then, performance is a function of both power and weight, or sail area and displacement.
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.
27 kwi 2018 · 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. There are numerous online DLR-calculators available on the net, just do a quick research in the search engine of your choice.
The Sail Area/Displacement Ratio. SA/D = SA/D 0.67. Where SA is sail area in square feet, and D is displacement in cubic feet.
