MULTIHULLED VESSEL Russian patent published in 1997 - IPC

FIELD: shipbuilding. SUBSTANCE: multihulled vessel has central float which is connected with, at least, two side floats; waterplane areas of side floats and distances between their center planes and center plane of vessel as a whole spreading in height by magnitude equal to, at least, 6 percent of distance between center plane of each side float and center plane of vessel are selected from the following relationship: , where n is number of side floats; Si is waterplane area of side float, sq.m; d_i is distance between center plane of i side float and center plane of vessel, m; Δ is displacement of vessel, metric tons; BC is distance between CG and CB, m; ratio of width of central float to its draft measured on existing waterline is equal to 1.0 and ratio of its length to width is equal to, at least, 8.0. EFFECT: increased running speed of vessel. 15 cl, 12 dwg
