Study Of The Resistance Calculation Of High Speed Catamaran On Planing Motion

As one kind of special high performence boats,because it has low wavemaking resistance and good stability and so on the remarkable merits ,high speed catamaran has attracted more and more researchers and shipyards during the past decades,and has become the nearly 20,30 years shipbuilding hot spot.But,at present as a result of technology development,commercial and technical information security and so on factor influence, nowdays the public technical data really is few .Especially regarding the planing catamaran,the correlation data is less fewer.This article with every effort will unify from the theoretical analysis and the ship model test embarks,first calculate the lift and friction of the hull with 2-dimentional time-domain theory.At the same time,taking stickiness disturber and friction disturber into account, preliminary estimate to under planing motion ship resistance performance, then will embark from the ship model test, transform the ship model resistance towing test result into the solid ship performance, carry on the two generalized compare and analyse the cause of the error ,then will draw the beneficial conclusion and provide some actual technical datas and the conclusion for the later high speed catamaran development.
