DESIGN AND OPERATIONAL EXPERIENCE OF THE SWATH SHIP NAVATEK-I

A presentation is attempted linking the historical development, genera l design considerations for Small Waterplane Area, Twin-Hull (SWATH) h ull shapes, the design of a particular SWATH, the Navatek I, and her o perational experience. The ''carrier vessel'' concept on which the Nav atek I is based is introduced. Principal dimensions and general arrang ements are shown. A parametric study of twin-strut SWATH hull forms fo r a hull of constant displacement is presented in some detail. Stabili ty and ship motion are discussed and actual data for the Navatek I pre sented. The overall structural analysis is briefly presented, includin g the method of analysis for the Navatek I. The SWATH captain's operat ional experience with the Navatek I during her extensive journeys is r elated to quite some extent.
