aary and Identlly by block i 



This report presents refinements of a previous momentum-integral 

 method for calculating three-dimensional turbulent boundary layers on 

 ship hulls. In particular the following refinements are made: the small 

 crossflow assumption is removed; numerical calculation of the double model 

 potential flow replaces the slender body potential flow; a more general
