Some Effects of Stern Configurations on Resistance and Propulsion Properties

Abstract

Some experimental results on the effects of stern configurations on both resistance and propulsion properties of simple hull forms are presented. Wave resistance is sensitively influenced by modification of stern configuration or attachment of an appended aft-body, which is attributable to the nonlinear free surface phenomena. Self-propulsion factors are also influenced by an appended aft-body which is located above a propeller.
