Abstract : This international biennial symposium promotes the exchange of naval research developments of common interest to the countries of the world. The forum encourages both formal and informal discussion of the presented papers, and the occasion provides an opportunity for direct communication between international peers. More than 200 participants from 13 countries attended the symposium. Ranging from newly graduated students to researchers of established international repute, the attendees represented a mix of experiences and expertise. They presented 48 papers in seven topical areas-nonlinear ship motions, viscous ship hydrodynamics, hydrodynamics in ship design, wave and wake dynamics, cavitation and bubbly flows, propulsion hydrodynamics and hydroacoustics, and frontier experimental techniques-chosen because of recent advances made in these areas. Examples of significant advances presented in the papers are the numerical solution of the nonlinear equations for timedependent ship motions, the prediction of vorticity flux from surface piercing accelerating bodies, the design of a novel foil catamaran ship, the emerging understanding of free-surface interactions with vorticity, explanations of acoustic emission from cavitation bubble breakup, the prediction of viscous flow around propellers, and the use of quantitative visualization of large-scale wake structures for a free-running body.
