Speed sailing records are sanctioned, since 1972, by the world sailing speed record council (wssrc). records are measured either by average speed over a specified distance or by total distance traveled during a specified time interval.. New from psychosnail, learn to sail online, course on how to sail for beginners. yes, it's time for online sailing lessons.. for a boat hull, a simple way to think of theoretical boat speed is that a vessel is limited by the wave that boats hull creates.that is, because it is a displacement vessel it doesn’t climb its bow wave, as a planning vessel would, which limits the boats speed.. Hull speed: it is otherwise called as displacement speed is the speed at which the wavelength of the bow wave (wave formed at the bow of the ship or boat, when it travels in water) is equal to the length of the boat. as the speed of boat increases from rest state, the bow wave's wavelength increases, and usually its crest-to-trough dimension.

Hull speed hull speed (measured in knots) is the theoretical limit at which your (displacement) hull can move through the water. it doesn't matter how much sail is in use, your boat can't go any faster than this in normal conditions.. It the wind is from behind the boat, then apparent wind speed is true wind speed minus boat speed. turning on the motor makes the force on the sail less. enough motor can make the wind force on the sail zero or negative..
