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. Webb24 nov. 2014 · View Masoud Aryanpour’s professional profile on LinkedIn.

Hull speed can be calculated by the following formula: $${\displaystyle v_{hull}\approx 1.34\times {\sqrt {L_{WL}}}}$$ where $${\displaystyle L_{WL}}$$ is the length of the waterline in feet, and $${\displaystyle v_{hull}}$$ is the hull speed of the vessel in knots If the length of waterline is given in metres and … Visa mer Hull speed or displacement speed is the speed at which the wavelength of a vessel's bow wave is equal to the waterline length of the vessel. As boat speed increases from rest, the wavelength of the bow wave increases, … Visa mer Because the hull speed is related to the length of the boat and the wavelength of the wave it produces as it moves through water, there is another formula that arrives at the same values … Visa mer • Ship resistance and propulsion • Wave making resistance Visa mer As a ship moves in the water, it creates standing waves that oppose its movement. This effect increases dramatically in full-formed hulls at a Froude number of about 0.35 (which corresponds to a speed/length ratio (see below for definition) of slightly less than 1.20 knot·ft … Visa mer Wave-making resistance depends on the proportions and shape of the hull: many modern displacement designs can exceed their hull speed even … Visa mer • Converter: knots > km/h & km/h > knots Visa mer Webb17 feb. 2009 · The hull speed formula for displacement monohulls is 1.34 x the square root of the waterline length. When planing, a monohull will exceed it's hull speed. Obviously this formula doesn't apply to catamarans. Even when not planing, they will travel much faster than what the hull speed formula predicts. list of wh questions speech therapy
