Abstract	AbstractDuring sailing by wind-driven thrust on the sail, a catamaran sailing yacht generates leeway and heeling. For predicting sail force, a model test was carried out according to running attitude. Through the model test, drag and side force of the real ship was predicted. A purpose of this study is to find sail force to C.E from changed attitude during running direction. By balance of hull and sail, a heeling force of designed sail is predicted. Also through heeling force and driving force, total sail force and direction from C.E are considered with changed mast including leeway and heeling. ※Keywords: Catamaran Sailing Yacht(쌍동형 세일링 요트), Sail force(세일력), Heeling force(기우는 힘), Driving force(전진력), Running Attitude(항주자세), Center of effort(풍압중심) 1. 서론 세일링 요트는 바람에 의해서 추진력을 가지게 된다. 항만 내에서 또는 황천이나 무풍 등의 특별한 경우를 제외하고는 일반적인 항해 중에는 바람의 힘으로만 항주하게 된다. 따라서 세일링 요트의 접수일: 2010년 5월 25일, 승인일: 2010년 6월 11일✝교신저자: hyjang@rims.re.kr, 051-974-5581 경우에 세일의 설계는 선형의 설계와 마찬가지로 중요한 비율을 차지하게 된다. 또한 최적의 효율을 갖는 세일을 만들기 위해서는 수조에서의 모형선 실험과 마찬가지로 세일의 유체성능을 해석하기 위해서는 풍동실험이나 CFD 수치계산 등이 수행되어야 하나, 이러한 경우 비교적 많은 시간과 비용이 들게 된다. 세일에 의해 발생하는 풍력은 각 항주자세별로 선체에 작용하는 유체력과 서로
