First the 1.34 is not really a constant, it is derived from the average leingth/width ratio of boats that were designed around 1900. It has little to do with modern boats. Secondly it doesn't take into account displacement. Webb24 nov. 2014 · View Masoud Aryanpour’s professional profile on LinkedIn.

WebbThe "fineness" of the hull apparently doesn't come into play using the 1.34 formula. A fat tub has the same "hull speed" as a kayak of the same LWL. Intuitively, this doesn't make sense to me. I appreciate that it will take more power to move the tub at hull speed, but the onset of drastically more power to move past hull speed is the same ... 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.
