摘要

Model and full-scale tests were conducted to investigate the use of drogues to prevent breaking wave capsizing of sailing yachts. A mathematical model was developed which simulates the motion of a boat and rogue in regular waves and in a breaking wave strike. A series drogue is recommended for optimum performance based on the results of this study. Design information for both series and conventional drogues is presented. Prior to this investigation of the use of drogues, comprehensive model tests were conducted in this country and in England to study the effect of sailing yacht design characteristics on breaking wave capsizing vulnerability. Although it was found that certain design characteristics such as beam/length ratio would adversely affect capsize performance, the effect was relatively small and a slightly larger wave would capsize all the designs. Accordingly this program and a similar program in England was directed toward the use of drogues as a solution which offered the promise of a large improvement in safety and which could readily be applied to the current fleet of sailing yachts.
