Web13 mei 2005 · How fast is this, it depends on the waterline length of your boat. If the waterline length is 30 ft, then find the square root of 30 ft. which is 5.47- now multiply the 5.47 times the chart or 1.1 which equals 6.01 knots, to change knots into m.p.h. multiply that answer 6.01 by 1.15 to = 6.91 m.p.h. Web3 sep. 2024 · Maximum "hull speed", in knots, is equal to about 1.3 X the square root of the waterline length of the hull in feet. For example, say you have a displacement hull with a waterline length of 25 feet, then the hull speed is 5 x 1.3 = 7 knots. Trying to propel the boat faster than this will result in enormous increasing power requirements. 2.

WebThe nautical measurement of speed is the knot. One knot is equal to about 1.15 mph. According to the World Sailing Speed Council, the current record holder for the fastest nautical mile is Alain Thebault from France with a speed of 41.69 knots -- or about 48 mph.

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, and usually its crest-to-trough dimension (height) increases as well. When hull speed is exceeded, a vessel in displacement mode will appear to be climbing up the back of its bow wave. Web30 aug. 2024 · Sailboat length/speed ratios are calculated as hull speed. For monohull designs, the hull speed calculation is (HS = 1.34 x √LWL). This determines the typical maximum speed of a boat based on its waterline length. ...
