This paper reports the design considerations and the evaluation of practical lowest size limits of SWATH hull form application. Static stability requirements have been considered from the very first design steps and the strut waterplane area has been minimized while assuring necessary stability of SWATH craft. The dynamic instability has been analysed numerically at four speeds. The results of an experimental program concerning resistance, roll decay and seakeeping performances are reported. Resistance towing tests have been performed in calm water in Froude number range from 0.316 to 0.844. Seakeeping tests have been carried out in regular waves reporting heave, pitch and vertical acceleration nondimensional responses at zero speed and at Fr=0.316. The reported results can be considered a contribution for the application of SWATH hull form in the design of small working craft or yachts with superior comfort characteristics.

Abstract

This paper reports the design considerations and the evaluation of practical lowest size limits of SWATH hull form application. Static stability requirements have been considered from the very first design steps and the strut waterplane area has been minimized while assuring necessary stability of SWATH craft. The dynamic instability has been analysed numerically at four speeds. The results of an experimental program concerning resistance, roll decay and seakeeping performances are reported. Resistance towing tests have been performed in calm water in Froude number range from 0.316 to 0.844. Seakeeping tests have been carried out in regular waves reporting heave, pitch and vertical acceleration nondimensional responses at zero speed and at Fr=0.316. The reported results can be considered a contribution for the application of SWATH hull form in the design of small working craft or yachts with superior comfort characteristics.
