The speed obtained by the equation equal the speed at which the bow wave length equal the waterline length or a Froude Number of 0.4. This is however a fairly rough estimate and displacement hulls have been developed that without planing can obtain …
Webb28 apr. 2010 · To find a boat’s D/L ratio, you first calculate its displacement in long tons (DLT), with 1 long ton equaling 2,240 pounds. Then take the boat’s load waterline length (LWL), multiply it by 0.01, and cube the result. Finally, take this result and divide it into DLT. The complete formula is as follows: D/L = DLT ÷ (0.01 x LWL)³.
