Abstract:

This report documents two computer programs which determine the wave resistance and propulsive performance of Small-Waterplane-Area Twin-Hull SWATH ships. These programs are SYNTHESIS and CLOSEFIT, and they use as input data the moments and offsets of ship geometry, respectively. While they both employ linearized ship wave theory and thin-ship approximation and share many subroutines, CLOSEFIT is a more refined program capable of furnishing superior results. On the other hand, SYNTHESIS is simpler and includes several additional subroutines which can determine the characteristics and performance of a SWATH ships propulsive system at both design and off-design conditions.
