Dr. Manuel Fluck presents joint work at Chesapeake Sailing Yacht Symposium

North Windships together with the North Design Service Team and their partners at the Wolfson Unit (University of Southampton, UK) have made significant progress in the development and design of DynaRigs for commercial ships.


Last week Dr. Manuel Fluck presented first results at the Chesapeake Sailing Yacht Symposium (CSYS) to an audience of scientists and industry professionals.


The Chesapeake Sailing Yacht Symposium is the world's longest-running technical forum dedicated to advancing the study of the art and science of sailing yacht design technology.

Professional yacht designers and a wide variety of sailing enthusiasts travel from around the world to attend the CSYS Symposia to present papers and exchange ideas on sailing.


Abstract from paper

For most of the past century sailing was (besides very few exceptions) associated with pleasure and racing only. Recently, however, this is changing as the commercial maritime transport sector becomes increasingly interested in direct wind propulsion systems. The reasons are obvious: increasing fuel cost (direct or though emission penalties) and environmental awareness (intrinsic or driven by customer demands). In this paper differences between the design requirements in the commercial market and the pleasure or racing yacht industry are discussed and enhancements to the existing design tools relevant for commercial studies are presented. Sailing yacht studies have repeatedly shown how important it is to design and optimize the aero and the hydro aspects of the vessel in synchrony. This is equally or even more important for commercial ships, where part of the thrust might still come from the engine. Thus, the engine together with economic objectives of the shipping operations enter into the design space. With DynaRigs already having proved highly successful in the pleasure yacht market and possessing key features which are attractive for the commercial shipping, it serves as a good case-study. A few select results are first presented when analyzing the aerodynamic design space alone. Detailed results from several performance analyses via our Performance Prediction Program (PPP) are then discussed as well as some outcomes from the structural analysis to show the importance of combined aero, structure, hydro, and potentially engine as well as economic design decisions. The paper concludes with an outlook on future work.
