Sailboat design for speed

Hull speed - wikipedia, 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.
