Web25 de fev. de 2004 · LCB = Longitudinal Center of Boyancy = The centroid of the underwater volume of the boat expressed as a longitudinal location. Unless otherwise specified LCB is usually understood to be the centroid when the boat is floating on its datum waterline (DWL) with zero trim. LCG = Longitudinal Center of Gravity. Web11 de jan. de 2024 · LCB in sea kayaks ranges from 49% for 'Fish forms' up to 55% for 'Swede forms'. Designs beyond these limits result in poor directional stability as in the Swede forms or lack of maneuverability as in the Fish forms. Vertical center of buoyancy (VCB) is the vertical coordinate of the displaced volume centroid.
