It is a function of the length of the wave created by the boat as it moves through the water. Wave speed is a function of wavelength; longer wavelengths are faster. Longer boats make longer waves.

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 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 ... how to slim waistlineWebb18 aug. 2015 · The hull speed formula we all use 1.34*srrt (lwl) is not a technical one, it's just a very rough guess. 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. novaliches to national museum

"WebbYou calculate the maximum hull speed (HS) by taking the length in feet (lwl), get the square root, and multiplying it by 1.34. HS = √ lwl * 1.34 HS = Hull Speed lwl = length at waterline So a 80 feet boat has a maximum hull speed of: √ 80 * 1.34 = 12 knots Sailboat Length and Hull Speed (Longer = Faster) Watch on Exceeding Hull Speed " - Theoretical hull speed formula
