Abstract

The research developed twin keel yacht for everyone which is able to stand erectly on mud flat without list and intended to commercialize the development product for popularization of west coast's marine leisure industry. Yacht's linear was utilized by "Blue Water21" has superior performance among the existing sailing yachts and twin keel model has been tested by calculation of mono keel's extent and its center of gravity. The result was that only 4 % of difference have been identified between mono keel and twin keel's hydrodynamic resistance which was smaller difference than predicted.

본 연구에서는 서해안의 해양레저 대중화를 위해 누구나 세일링을 즐길 수 있고, 두 개의 킬로 선체를 지지하여 육상 및 갯벌에서도 선체가 기울지 않고 설 수 있는 트윈킬 요트를 개발하고자 한다. 기존 세일링 요트중 성능이 좋은 편인 블루워터21의 선형을 활용하고 트윈킬 요트의 경우 모노킬 요트보다는 저항성능이 불리할 것으로 예상되므로, 블루워터21의 모노킬 면적 및 무게중심 등을 고려한 트윈킬을 개발하여 모형시험을 수행하였다. 그 결과, 모노킬과 트윈킬의 저항성능에 대한 차이가 약 4 %정도로 예상보다 크지 않음을 확인하였다.
