Powering for medium speed wave-piercing catamarans comparing waterjet and screw propeller performance using model testing
Abstract
A comparative study of the powering performance ofwaterjet and screw propeller propulsion for medium speedwave-piercing catamarans using model testing is presentedand discussed. The self-propulsion tests for both screw andwaterjet propulsion were carried out to determine the ship'spower at various speeds. The testing conditions for bothpropulsion system consisted of a speed range of 20 to 30knots and two displacements, i.e. light and heavydisplacements, at level static trim. The main comparisonparameters are the estimated overall propulsive efficiencyas well as the delivered power estimates at model scale.
